User’s Guide

4.4.1

Using the Clamp-on Ferrites

Clamp-on ferrites are provided with this product for the use of improving its

electromagnetic (EM) immunity in environments of excessive EM interference.

During EMC testing we found that ferrites clamped around the probe cables

and power cord reduced the risk that EM interference affects measurements.

Therefore, we recommend that the clamp-on ferrites provided (Steward P/N

28A2025-0A2) be used on the cables of probes attached to this product, espe-

cially if it the product is used near sources of EM interference such as heavy in-

dustrial equipment.

To attach a ferrite to a probe cable, make a loop in the cable near the connector

and clamp the ferrite around half of the loop as shown in Figure 1. The ferrite

can be easily snapped open and moved to a new probe when needed.

The 1529 draws power from either a 15-volt DC power supply (the included

AC adapter) connected to the DC input or the internal re-chargeable battery

pack. To use the AC adapter, plug it into a wall outlet of the appropriate voltage

and insert the DC plug into the DC power input of the 1529 (see Figure 3 on

page 16.)

Switch the Power On

Power is turned on and off with the power switch located on the top right cor-

ner of the back panel. To switch the power on, toggle the power switch to the

‘ON’ position. To switch power off, toggle the power switch to the ‘OFF’ posi-

tion. The instrument takes a few seconds to power up, initialize, and begin nor-

mal operation. A self-test is performed displaying the channel configuration

and status of the system, calibration, GPIB, memory, and buttons. If the ther-

mometer readout calibration has expired, the user is notified and must press the

Display

General Operation

This section explains basic operation of the 1529 thermometer readout. De-

tailed operation of the 1529 is explained in Sections 7 and 8. Section 7 explains

the menu structure and the functions available in the menu structure and Sec-

tion 8 explains the communications interface for operating the 1529 remotely.

6.1

Display

The 1529 display consists of two parts. The top portion of the display is used

for displaying the measurements from one to four inputs. The bottom portion of

the display is reserved for the programmable fields and field display sets. Infor-

mation about the channels and measurements can be displayed in greater detail

such as min, max, spread, standard deviation, and many other functions. When

the measure period is 0.1 or 0.2 seconds (fast measurement mode), the pro-

grammable fields and field display set information are not displayed.

6.2

Changing Units

The 1529 thermometer readout is capable of displaying temperature in Celsius

(C), Fahrenheit (F), or Kelvin (K). (Displaying in units of Ω, KΩ, or mV is also

available through the PROBE menu and is channel specific.) Temperature units

are changed on all channels (not individually) by pressing the buttons on the

front panel when not in the menu structure. Press the Unit, LR, buttons to

scroll forward and backward through C, F, or K. All channels or fields that are

displaying temperature on the upper or lower display are updated to the new

units.

Channels that are set to Ω, KΩ, or mV in the PROBE menu are left unchanged

when temperature units are modified. Changing the units resets the statistical

calculations (displayed in the bottom portion of the display).

6.3

Battery

The 1529 thermometer readout has a built-in nickel-metal-hydride battery pack

that can power the instrument for about eight hours before needing to be re-

charged. The battery discharges more quickly when the display backlight is

used. The percent of battery charge remaining is displayed on the bottom por-

tion of the display when the battery power is being used. The battery percent-

age is approximate and should only be used as a general guideline when

determining the length of charge remaining. The battery is recharged in situ

(while in place) using the AC adapter that is provided.

Plug the AC adapter into the wall outlet and connect the DC plug of the adapter

into the 1529. The battery is charged as necessary whether or not the instru-

ment is switched on. The power control circuit inside the instrument manages

battery charging and stops charging the battery automatically when the battery

1529 Chub-E4 Thermometer Readout

User’s Guide

is fully charged. Only charge the battery when ambient temperature is between

16°C and 30°C (61°F and 86°F) It normally takes about three hours to fully

charge the battery. The instrument can be operated while the battery is being

charged. The charging indicator on the back panel is green when the battery is

fully charged and amber when being charged using the AC adapter.

The battery may self-discharge over several months, especially if the tempera-

ture is warm. The battery pack can be used for a minimum of 500 charge-dis-

charge cycles before needing to be replaced. Replacement battery packs are

available from the manufacturer. The battery pack can be easily removed and

replaced in the field by following this procedure:

1. Power the 1529 off and unplug the AC adapter from the unit.

2. Turn the 1529 over to expose the battery compartment. Remove the bat-

tery cover hex screw. Place the screw in a safe place so it won’t get lost.

Flip open the battery cover to reach the battery pack.

3. Remove the battery pack. Gently disconnect the battery plug connector.

4. Attach the polarized plug of the new battery pack onto the connector.

Note: The battery plug is polarized and can only be plugged in one di-

rection. DO NOT force it. Place the battery pack in the battery

compartment.

5. Close the battery cover and replace the screw. Avoid pinching the battery

wires.

6. Plug in the AC adapter and charge for a minimum of four hours for the

initial charge. Used batteries must be disposed of properly. Check your

local regulations for additional information. You may return used batter-

ies to the manufacturer. Never dispose of batteries in fire as this may re-

sult in an explosion with the possibility of personal injury or property

damage.

When the battery charge is not at 100%, the measurement accuracy is not af-

fected. If the power is interrupted while the instrument is logging measure-

ments (on demand or automatically), the logged data is preserved and logging

resumes when the power is restored.

6.4

Probe Input Modules

The 1529 can be configured in three ways:

• Two RTD/thermistor input modules.

• Two thermocouple input modules.

• One RTD/thermistor and one thermocouple input module.

Each input module supports two channels. Your 1529 thermometer readout is

configured at the factory and is not field changeable. Input modules should

never be removed for any reason.

6 General Operation

Probe Input Modules

All possible configurations are shown in Figure 3 on page 16.

6.4.1

Connecting a PRT or Thermistor Probe

PRT and thermistor probes are attached to the resistance input module via Hart

Scientific mini-DWF connectors. These patented connectors accept bare wire,

spade, or mini banana plug terminations. The connectors are color coded for

ease in connecting lead-wires.

When using 2- and 3-wire sensors, the accuracy of the 1529 is reduced as

stated in the specifications. Compensation is made for 3-wire PRTs, but the dif-

ference in lead resistance affects the measurement accuracy. The 1529 ther-

mometer readout is unable to compensate for 2-wire lead resistance.

Attach the lead-wires of the probes as shown in Figure 5 on page 22. The top

termainals sense current and the bottom terminals sense potential.

6.4.2

Connecting a Thermocouple

The 1529 thermocouple input module accepts both standard and sub-miniature

size thermocouple connectors. The connection is made with the positive termi-

nal on the right and the negative terminal on the left. You must use a connector

that matches the thermocouple type for the internal RJC to be accurate. For ex-

ample, if you are using a type K thermocouple you must also use a type K con-

nector, which is made from the same type of metal. For best results, wait two

minutes before measuring after inserting the thermocouple connector into the

input module.

6 General Operation

DC Power Source

6.5

DC Power Source

Caution: For CE compliance and for performance, use only the AC

adapter shipped with the instrument by Hart Scientific. If the AC adapter

needs to be replaced, contact an Authorized Service Center (see Section

1.3).

The DC power source provides power to charge the battery. It can also be used

to power the 1529 while the battery is being charged. The AC adapter provided

with the 1529 is intended for these purposes. The DC power source plugs into

the DC power input on the back panel of the instrument. The AC adapter has

circuits with high voltages inside that could present danger of electric shock or

fire if exposed. If the AC adapter is damaged in any way or becomes hot, dis-

continue use immediately, disconnect the adapter from any AC supply, and re-

place the adapter. Do not attempt to open, repair, or continue using a damaged

or defective AC adapter.

6.6

6.7

Power On Self-Test

When power is turned on, the 1529 performs a self-test checking the system, all

channels, calibration, GPIB, memory, and buttons. If an error occurs, an error

message is displayed. See Section 11.1, Troubleshooting for additional infor-

mation on error messages.

Display Backlight and Contrast

The display backlight is adjustable for use in varying lighting conditions. The

four backlight modes are accessible in the CHANNEL menu DISPLAY OP-

TIONS function. If the display appears faded, dark, or blank, adjust the con-

trast (off, low, medium, high) using the front panel contrast buttons.

6.8

Taking Measurements

The procedure for configuring the 1529 thermometer readout to take measure-

ments on a particular input channel requires the following: (1) connecting the

sensor to the appropriate input channel , (2) enabling the channel, and (3) se-

lecting the conversion type and probe characterization values.

6.8.1

Connecting the Sensor

Connect the sensor to the RTD/Thermistor channel(s) or thermocouple chan-

nel(s) that you want to measure. Refer to Section 7.4, Probe Input Modules, for

additional information.

User’s Guide

6.8.2

Enabling the Channel

Channels are set first by selecting either simultaneous or scan mode in the

CHANNEL menu CHANNEL MODE function. Simultaneous mode shows one

to four channels in the upper display simultaneously. Scan mode shows one

channel at a time (in large digit format) scanning through one to four channels

depending on the channels that are enabled. After the mode has been selected,

use the CHANNEL menu ENABLE CHANNEL function, to select the channel

to be displayed. Any channel set to ‘Off’ is not displayed. See Sections 7.1.3,

Channel Mode, and 7.1.2, Enable Channel, for more information.

6.8.3

Selecting Conversion Type and Probe Characterization

Before the 1529 can accurately measure temperature, it must be configured to

calculate temperature from the resistance or voltage of the sensor. There are

many temperature conversion algorithms available and the one to use depends

on the type of sensor and its calibration. Many conversion algorithms use coef-

ficients that characterize the sensor. Coefficients are determined when the sen-

sor is calibrated. SPRTs and RTDs often use the ITS-90 algorithms and are

provided with ITS-90 characterization coefficients. Thermistors often use the

Steinhart-Hart algorithms and coefficients. Thermocouples use standard tables

or equations depending on its type. For additional information on conversion

types, see Section 7.2, Probe Menu.

The conversion type and characterization coefficients for a sensor are specified

using the PROBE menu EDIT PROBE function (see Section 7.2.1).

6.9

Fast Measurement Mode

Fast Measurement Mode applies to measure periods of 0.1, 0.2, or 0.5 seconds.

This mode allows measurements to be displayed or logged quickly.

Normally, when each measurement is made a self-calibration of the measure-

ment circuit is performed simultaneously during the measurement process to

offset errors from component drift and spurious EMFs. For measure periods of

0.1, 0.2, and 0.5 seconds, the fast measurement rate is achieved by foregoing

the self-calibration. The drawback to this Fast Measurement Mode is the accu-

racy of the measurement may be poor and subject to drift. Accuracy can be

temporarily improved using the AUTO-CAL function that appears in the

CHANNEL menu when in this Fast Measurement Mode. The AUTO-CAL

function causes the instrument to perform a single self-calibration of the mea-

surement circuit then resume fast measuring (without automatic

self-calibration).

See Section 8.1.1 for detailed information on using the Fast Measurement

Mode.

Data Logging

6.10

Data Logging

Data can be logged either on demand or automatically at a user-selected inter-

val. When data is logged, readings are stored to the instrument's memory and

assigned a label for easy recall and organization of data. Up to 100-demand log

and 8,160 auto log readings can be stored. When data is being logged, the left

bottom corner of the main display shows a strip-recorder indicator.

ITS-90 Conversion

The ITS-90 conversion is for PRTs calibrated and characterized using the Inter-

national Temperature Scale of 1990 equations. The parameters that appear

when ITS-90 is selected are RTPW, A4, B4, A, B, C, and D. These should be

set with the corresponding values that appear on the calibration certificate for

the PRT. The parameter RTPW takes the triple point of water resistance from

the certificate. The parameters A, B, C, and D take the an, bn, cn, and d coeffi-

cients from the certificate, where n is a number from 6 to 11. Parameters A4

and B4 take the a4 and b4 coefficients on the certificate. Any ITS-90 parameter

of the 1529 that does not have a corresponding coefficient on the PRT certifi-

cate must be set to 0.

When the ITS-90 conversion type is selected, the RANGE, WIRES, and coeffi-

cients are displayed on the right portion of the bottom of the display. The UD

buttons are used to scroll through the coefficients. Use the Enter button to edit

and to save the new settings. Use the LR buttons to change each digit of the

settings. Press and hold the Exit button to cancel to the main display or press

The WIRES parameter sets the appropriate number of lead wires from the sen-

sor. This parameter can be set to 2-, 3-, or 4-wires. See Figure 5 on page 22 for

the wiring configuration.

The following table shows which parameter to set for each of the coefficients

that may appear on the certificate. Note: If the certificate has two sets of coeffi-

cients, one set for “zero-power” calibration and one set for 1 mA calibration,

use the coefficients for the 1 mA calibration.)

The user-defined parameters for the thermistor T(R) conversion are A0 (A₀)

through A3 (A₃) as shown on a typical Hart Scientific thermistor calibration re-

port. If A₂is not used, as is the case with some calibrations, A2 should be set to

0.0.

Note: Thermistor coefficients stated on the thermistor calibration report may be

labeled differently. The best way to identify the coefficients to use with this

type is to match the equation above with the equation given on the calibration

report. Also, recognize that the coefficients for this equation generally have

negative exponents, e.g. A3: 1.39456E-07.

Thermistor R(T) Conversion [THERM-R]

The following Steinhart-Hart equation is used for the thermistor R(T)

conversion:

r(T[K ]) = exp[B₀+ B₁T⁻¹+ B₂T⁻²+ B₃T⁻³

]

The user-defined parameters for the thermistor R(T) conversion are B0 (B₀)

through B3 (B₃) as shown on a typical Hart Scientific thermistor calibration re-

port. If B₂is not used, as is the case with some calibrations, B2 should be set to

YSI-400 Conversion

The YSI-400 conversion type is for 2252Ω thermistors matching the character-

istics of the YSI-400 series of thermistors.

There are no user programmable coefficients associated with this conversion

type. Use the Enter button or Exit button to exit the menu.

Thermocouple Volts [Vin[mV]]

The thermocouple volts displays the measurement in volts rather than

temperature.

Note: When selecting volts as the conversion type for thermocouples, no

cold-junction compensation is available. The value measured and displayed is

the uncompensated voltage as sensed at the input of the module.

Standard Thermocouple Conversions

Note: An Application Note for use of Tungsten-Rhenium and other

thermocouples is available at www.hartscientific.com.

Standard thermocouple conversions include types B, E, J, K, N, R, S, T, and

Au-Pt. Voltage is converted to temperature using standard reference functions.

(For additional information consult the publication NIST Monograph 175.)

You can specify internal or external reference junction compensation (RJC)

with the RJC parameter. (See Table 9 on page 125.) With internal RJC, the tem-

perature of the thermocouple cold junction is measured automatically and used

to calculate the absolute temperature of the thermocouple. With external RJC, a

reference junction at a known fixed temperature is used and the value of this

fixed temperature reference must be entered in the RJT parameter and is used

to calculate the absolute temperature of the thermocouple.

Conversions for each of the thermocouple types accept functional calibration

data. This can be used to improve the measurement accuracy. The parameter,

Tn, is the temperature of the point in degrees Celsius. The parameter, ADJn, is

the temperature deviation from the reference function at the point in degrees

Celsius. The temperature measurement is adjusted by this amount when mea-

suring at this temperature. A polynomial interpolation function is used for mea-

surements between calibration points. If calibration data is not available or is

not to be used, the ADJn parameters should all be set to 0.0. This causes the

temperature to be calculated according to the standard reference functions.

7.2.1.11

Thermocouple Polynomial Conversion

Note: An Application Note for use of Tungsten-Rhenium and other

thermocouples is available at www.hartscientific.com.

The thermocouple polynomial conversion allows calculation of temperature by

polynomial conversion.

When the Thermocouple Polynomial conversion type is selected, the coeffi-

cients are displayed on the right portion of the bottom of the display. Use the

UD buttons to scroll through the coefficients. Use the Enter button to edit

and save the new setting. Press and hold the Exit button to cancel to the main

display or press the EXIT button to cancel and to move to the next parameter.

On the last parameter, press the Exit button to exit to the menu.

The following equation is used for the thermocouple polynomial conversion:

t(E[mV])[°C ] = C_iEⁱ

∑

i = 0

1529 Chub-E4 Thermometer Readout

User’s Guide

The user-defined parameters for the thermocouple polynomial conversion are

the coefficients c₀(C0) through c₆(C6). The user can specify internal or exter-

nal reference junction compensation (RJC; see Table 9 on page 125). If external

RJC is selected, the user enters the temperature of the RJC reference in the ref-

erence junction temperature (RJT) parameter.

The output of the thermocouple, in millivolts, at 25°C with the reference junc-

tion at 0°C, is mV (25°C). For example, for a type K thermocouple, mV(25°C)

is 1.0002.

Copy Probe

The COPY PROBE function allows you to copy a set of probe parameters from

one channel or memory location to another. The parameters are copied from the

user selected source channel or memory location into the current channel. The

COPY PROBE function can be password protected to restrict access. See Sec-

tion 7.5.3, Password, for more information. If this function is password pro-

tected, the user is prompted to enter the password to gain access. If an incorrect

password is entered, the display shows the message PASSWORD INCOR-

RECT and access is denied. If the correct password is entered or if this function

is not password protected, the bottom portion of the display appears showing

the source channel or memory location, the probe serial number, and the con-

version type. The destination channel or memory location is displayed after the

source channel type is selected.

You may select between 0.1, 0.2, 0.5, 1, 2, 5, 10, and 30 seconds, 1, 2, 5, 10,

and 30 minutes or 1 hour. The LOG PER must be set to a value less than or

equal to the measurement period. The 1529 will not log readings faster than the

measurement period. The measurement period is set in the MEASURE PE-

RIOD function of the CHANNEL menu and is the rate at which readings are

taken.

If the log period is set to a value less than the measure period the following

message is displayed in the lower portion of the display.

DATA WILL BE LOGGED NO FASTER THAN

THE MEASURE PERIOD (X SEC ).

Press ENTER to continue…

The X in the message is the current measurement period. After the Enter but-

ton is pressed, the measurements are logged at the current measure period.

The COUNT parameter is for selecting the total number of readings to log. The

default is 8,160, which is the maximum number of readings that can be logged.

If the count is set to 10 and two channels are displayed on the screen at the time

logging starts, five readings from each channel are logged for a total of 10 read-

ings. The auto log automatically stops after the number of readings selected is

reached or when the user stops the log manually.

Press the LR buttons to change a setting and the UD buttons to scroll be-

tween the parameters. Press Enter button to save the new setting. Press and

hold the Exit button to cancel to the main display or press the EXIT button to

cancel and to move to the next parameter.

7.5.1.1

Serial

When the SERIAL option is selected, the parameters for the serial port are dis-

played on the bottom portion of the display. These parameters are: BAUD, SER

PER, LF, PRINT, and ECHO.

The BAUD parameter allows the user to select the baud rate for communica-

tions on this port. The user may choose between 1200, 2400, 4800, 9600, and

19200. The default baud rate is 9600.

The SER PER parameter allows the user to select the interval at which mea-

surements are transmitted over the serial port. The user may choose between

0.1, 0.2, 0.5, 1, 2, 5, 10, and 30 seconds, 1, 2, 5, 10, and 30 minutes, and 1

hour.

The LF parameter allows the user to specify whether a linefeed character

(ASCII 0A hex or 10 decimal) is appended to the end of each line transmitted

over the serial port. Selecting ON sends both a carriage return (ASCII 00 hex or

13 decimal) and a linefeed. Selecting OFF sends only a carriage return.

The PRINT parameter allows the user to enable printing measurements over the

serial port. Selecting ON enables printing and selecting OFF disables printing.

With slower MEA PER (see Section 7.1.1) and SER PER rates of 1 second or

more, measurements are printed with the channel number, measured value,

unit, time, and date, all separated with spaces. With faster rates, less than 1

second, only the measured value is printed.

8 Digital Communications Interface

Overview

Digital Communications Interface

8.1

Overview

The communication feature allows an external device, such as a computer, to

communicate with the 1529 to obtain measurement data and control operating

conditions. Communication is accomplished by issuing commands to the 1529

through RS-232 or IEEE-488 communication ports.

8.2

Communications

The thermometer readout is equipped with an RS-232 serial interface, and op-

tionally a GPIB port. The serial interface allows communications up to dis-

tances of approximately 50 feet. The serial interface and GPIB port allow the

user to access the functions, parameters, and settings discussed in Section 7,

Menu Functions.

8.2.1

Serial Wiring

The serial communica-

tions cable attaches to the

thermometer readout

through the DB-9 connec-

tor at the back of the in-

strument. Figure 49 shows

the pin-out of this connec-

tor and suggested cable

wiring. This type of cable

is typically referred to as a

“null modem” cable. To

eliminate noise, the serial

cable should be shielded

with low resistance be-

tween the connector

(DB9) and the shield.

The serial period, baud

rate, linefeed, and echo

are programmable. Refer

to Section 7.5.1.1, Serial

Port, for instructions on

accessing and setting

these parameters.

All commands sent to the

terface must be terminated with a carriage return or linefeed character.

8.2.2

GPIB Communications

The GPIB interface allows the Model 1529 to be connected to an IEEE-488 bus

along with other instruments. A system controller can remotely control the op-

eration of the Model 1529 and read measurements.

8.2.2.1

Capability

The Model 1529 GPIB interface conforms to standard IEEE-488.2, 1992. Its

capabilities are identified as SH1, AH1, T6, L4, SR1, DC1, and E2. The inter-

face has the capabilities of talk, listen, serial poll, and device clear. There is no

capability for talk-only, listen-only, extended talk or listen, parallel poll, re-

mote-local control, or trigger nor can it act as a controller. The IEEE-488 com-

mands GET, GTL, LLO, and REN are accepted without error but ignored.

8.2.2.2

8.2.2.3

Connection

The IEEE-488 port is located on the back of the 1529. Use a standard

IEEE-488 cable to connect to your GPIB controller. A shielded cable should be

used to prevent EM emission.

Device Setup

The Model 1529 system must be set up to respond to the controller address.

Refer to Section 7.5.1.2, GPIB, for setting address and other parameters for the

IEEE-488 port.

Command Syntax

The 1529 accepts commands that set parameters, execute functions or respond

with requested data. These commands are in the form of strings of ASCII-en-

coded characters. As far as possible, the 1529 conforms to IEEE-488.2, 1992

and SCPI-1994. One notable exception is that compound commands are not al-

lowed as explained below.

Commands consist of a command header and, if necessary, parameter data. All

commands must be terminated with either a carriage return (ASCII 0D hex or

13 decimal) or new line character (ASCII 0A hex or 10 decimal).

Command headers consist of one or more mnemonics separated by colons (:).

Mnemonics may use letter characters, the underscore character (_), and possi-

bly numeric digits as well. Commands are not case sensitive. Mnemonics often

have alternate forms. Most mnemonics have a long form that is more readable

and a short form consisting of three or four characters that is more efficient.

1529 Chub-E4 Thermometer Readout

User’s Guide

A mnemonic may end with a numeric suffix that specifies one of a set of inde-

pendent function blocks such as input channel data paths. If a numeric suffix is

omitted when a particular block must be specified, an error is generated

(“Header suffix out of range”).

Query commands are commands that request data in response. Query com-

mands have a question mark (?) immediately following the command header.

Responses to query commands are generated immediately and placed in the

output buffer. Responses are then transmitted automatically over the RS-232

port. When using the IEEE-488 interface, responses remain in the output buffer

until read or until another command is received or the power is turned off. Re-

sponses are lost if not read before the next command is received. Each input

buffer holds 128 characters and each output buffer holds 256 characters.

Some commands require parameter data to specify values for one or more pa-

rameters. The command header is separated from the parameter data by a space

(ASCII 20 hex or 32 decimal). Multiple parameters are separated by a comma

(,).

The 1529 does not allow compound commands (multiple commands per line

separated with semicolons). All commands are sequential. The execution of

each command is completed before subsequent commands are processed.

8.4

Commands

Table 3, Alphabetical List of Commands in Section 8.3.1, lists the commands

in alphabetical order. In this section the commands are arranged into the fol-

lowing groups:

Measurement Commands – commands for reading measurement data.

Measurement Control Commands – commands for the timing and action of

the measurement process.

Channel Commands – commands for selecting channels.

Probe Commands – commands for temperature conversion and probe

characterization.

Calibration Coefficient Commands – commands for channel calibration

coefficients.

Display Commands – commands for display options and settings.

Logging Commands – commands for automatic and demand logging.

System Commands – commands for general system configuration parameters.

Communication Interface Commands – commands for controlling the inter-

face configuration(serial port and IEEE).

Date and Time Commands – commands for setting the date, time and the date

and time formats.

8 Digital Communications Interface

Commands

Password Commands – commands for enabling and disabling the password,

for setting the password, and for checking the state of the password.

Status Commands – commands to report the status and condition of the

instrument.

Each section provides the command structure (long and short format), a de-

scription of the command purpose, a command example, an example of what

the command returns (as applicable to query commands), and notes specific to

the command. The following apply to each group of commands.

• Numeric data, specified by the mnemonic, <num>, uses ASCII characters

to represent numbers. Numbers may contain a plus or minus (‘+’ or ‘-’)

sign, decimal point (‘.’), and exponent (‘E’ or ‘e’) with its sign. If a frac-

tional component is received when only an integer is required, the number

is rounded to the nearest integer without any resulting error message. The

mnemonics DEF, MIN, and MAX are often acceptable for the default,

minimum, and maximum value respectively. Unit suffixes, such as V or

OHM, can be appended to numeric parameters and are accepted without

error but ignored.

• Unrecognized commands or commands with incorrect syntax or invalid

parameters generate error messages in the error queue.

• Upper case letters designate syntax that is required when issuing the com-

mand. Lower case letters are optional and may be omitted.

• <> indicates a required parameter.

• [] indicates optional parameters.

• () indicates a group of parameters that must be used together.

• For query commands, specifying the MIN, MAX, or DEF parameter

causes the instrument to respond with the minimum, maximum, or default

setting respectively.

• For set commands, specifying the MIN, MAX, or DEF parameters causes

the instrument to use the minimum, maximum, or default setting respec-

tively.

• ‘|’ indicates alternate parameter values.

• <chn> indicates a channel number is required.

• <dest chn> indicates a destination channel is required.

• <n> indicates a number is required.

• <num> indicates numeric value is required.

• <chn list> indicates a list of channel numbers is required.

• <bool> indicates a Boolean value (0 or 1) is required. The mneumonics

OFF and ON are also accepted for 0 and 1, respectively.

• <conv> indicates a conversion mnemoic is required.

• <param> indicates a parameter name is required.

8.4.1

Measurement Commands

The measurement commands are used to read information on the statistical cal-

culations and for reading the most recent measurement for a specified channel.

The measurement commands are not password protected.

8.4.1.1

CALCulate:AVERage:CLEar

Clears the statistical functions for all channels.

CALC:AVER:CLE

The *RST command clears the statistical functions.

8.4.1.2

CALCulate<chn>:AVERage<n>:DATA?

Returns the value of a statistical calculation for a given channel.

CALC3:AVER1:DATA?

0.017

The CALCulate suffix, <chn>, specifies the channel (1 to 4). The AVERage

suffix, <n>, specifies the calculation type. See Table 4 on page 122 for the Sta-

tistical Calculation Types.

8.4.1.3

CALCulate:AVERage<n>:TYPE?

8 Digital Communications Interface

Commands

The AVERage suffix, <n>, specifies the calculation type number. See Table 4

on page 122 for the Statistical Calculation Types.

8.4.1.4

FETCh? [<chn>]

Returns the most recent measurement for the specified channel.

FETC? 1

0.0000011

1,2,0.0011,mV,14,5,35,2000,9,5

The <chn> parameter specifies the channel (1 to 4). If the <chn> parameter is

omitted, the most recent measurement is returned regardless of the channel. If

simultaneous sampling is on, the measurement from the lowest enabled channel

number is returned. This command does not affect the measurement action.

If the extended format setting is OFF (see Section 9.4.1.5, FORMat:STAMp

<bool>) the response is only the measurement value in units of temperature,

volts, or ohms depending on the selected probe type or temperature unit. With

this format kohms and millivolts are converted to ohms and volts respectively.

If the extended format setting is ON the measurement is returned in a

comma-delimited format as follows.

Measure status (0 if the measurement has been read previously or 1 if this is a

new measurement,

channel number,

measurement value,

scale,

hour,

minute,

seconds,

year,

month,

day the measurement was made

With this format kohms and millivolts are not converted to ohms and volts.

This command may return the same reading if a new reading has not yet been

obtained. If only new readings are desired, the FORMat:STAMp command can

be used to enable the extended format option and any readings in which the

value of the first field is 0 can be ignored or else the STATus:MEASure? com-

mand can be used to determine if a new reading is available for a desired

channel.

9 Calibration

PRT and Thermistor Calibration

Calibration

Each channel of the 1529 is calibrated independently of the other channels and

has its own set of calibration parameters. The 1529 should be calibrated at reg-

ular intervals to ensure that it continues to measure with proper accuracy. Cali-

bration should only be done by qualified, authorized personnel. When the 1529

is recalibrated, all four channels are calibrated each calibration cycle. The cali-

bration label indicates the calibration date and recalibration due date for the en-

tire instrument.

PRT Calibration Parameters

Three adjustable parameters are used for calibration: C0, C100, and C400. The

C0 parameter directly affects the measurement at 0Ω. It has negligible effect at

100Ω but significant affect at higher resistances. The C100 parameter directly

affects the measurement at 100Ω. It has negligible effect at 0Ω and proportion-

ately greater effect the higher the resistance. The C400 parameter directly af-

fects the measurement at 400. It has negligible effect at 0Ω and 100Ω with

greater effect as the resistance increases. Each of the parameters has positive ef-

fect at their primary resistances: increasing the value of the parameter increases

the measured resistance. The theoretically normal value for each is 0.

1529 Chub-E4 Thermometer Readout

User’s Guide

The calibration parameters C0, C100, and C400 can be adjusted to optimize the

accuracy. These password-protected parameters are accessed from the CALI-

BRATION function of the SYSTEM menu.

9.1.2

PRT Calibration Procedure

Calibration requires adjustment of the C0, C100, and C400 parameters at three

specific input resistances. If the resistances used are approximately 0Ω, 100Ω

and 400Ω respectively the adjustments are independent and the procedure is

simple. The order in which the adjustments are performed is important. The ad-

justment of the C400 parameter must be done last as the adjustments of C0 and

C100 affect the measurement at 400Ω but C400 does not affect the measure-

ments at 0Ω or 100Ω. Each channel must be calibrated. Set the conversion type

to RES to display resistance (see Section 7.2.1.5) and the RANGE parameter to

100Ω. The calibration should be performed with a four-wire connection and

with the probe wiring parameter set to four-wire (see Section 6.4, Connecting

the Probe). The accuracy required of the resistance standards is 1/4 of the in-

strument accuracy; that is 0.000125Ω at 0Ω, 0.0006Ω ( 6 ppm) at 100Ω, and

0.0024Ω (6 ppm) at 400Ω. The recommended procedure is as follows:

Connect a 0Ω resistor to the input and measure its resistance. If a short-

ing wire is used the wire should run from the C2 terminal to the C1 ter-

minal to the P1 terminal to the P2 terminal (See Figure 50). Note the

average error in the measurement. Adjust the C0 parameter by subtract-

ing the measured error. For example, if the input is exactly 0.0000 and

the readout shows –0.0011, adjust the C0 parameter by adding 0.0011.

Figure 50 Using a Shorting Wire

Connect a 100Ω resistor (6 ppm accuracy) to the input and measure its

resistance. Note the average error in the measurement. Adjust the C100

parameter by subtracting the measured error. For example, if the input is

exactly 100.0000Ω and the readout shows 100.0295Ω, adjust the C100

parameter by subtracting 0.0295.

PRT and Thermistor Calibration

Connect a 400Ω resistor (6 ppm accuracy) to the input and measure its

resistance. Note the average error in the measurement. Adjust the C400

parameter by subtracting the measured error. For example, if the input is

exactly 400.0000Ω and the readout shows 399.9913Ω, adjust the C400

parameter by adding 0.0087.

4. Record the date in the DATE parameter and set the DUE parameter to

the desired calibration interval.

Verify the accuracy at 0Ω, 25Ω or 50Ω, 100Ω, 200Ω, and 400Ω on each

channel.

9.1.3

Thermistor Calibration Parameters

Three adjustable parameters are used for calibration: C0K, C10K, and C100K.

The C0K directly affects the measurement at 0Ω. It has negligible effect at 10

kΩ but significant affect at higher resistances. The C10K directly affects the

measurement at 10 kΩ. It has negligible effect at 0Ω and proportionately

greater effect the higher the resistance. The C100K directly affects the mea-

surement at 100 kΩ. It has negligible effect at 0Ω and 10 kΩ with greater effect

as the resistance increases. Each of the parameters has positive effect at their

primary resistances: increasing the value of the parameter increases the mea-

sured resistance. The theoretically normal value for each is 0.

The calibration parameters C0K, C10K, and C100K can be adjusted to opti-

mize the accuracy. These parameters are accessed from the CALIBRATION

function of SYSTEM menu.

9.1.4

Thermistor Calibration Procedure

Calibration requires adjustment of the C0K, C10K, and C100K parameters at

three specific input resistances. If the resistances used are approximately 0Ω,

10 kΩ and 100 kΩ respectively the adjustments are independent and the proce-

dure is simple. The order in which the adjustments are performed is important.

The adjustment of the C100K parameter must be done last as the adjustments

of C0K and C10K affect the measurement at 100 kΩ but C100K does not affect

the measurements at 0Ω or 10 kΩ. Each channel must be calibrated. Set the

conversion type to RES to display resistance and set the RANGE parameter to

10KΩ. The accuracy required of the resistance standards is 1/4 of the instru-

ment accuracy; that is 0.12Ω at 0Ω, 0.25Ω (25 ppm) at 10 kΩ, and 2.5Ω (25

ppm) at 100 kΩ. The recommended procedure is as follows:

Connect a 0Ω resistor to the input and measure its resistance. If a short-

ing wire is used the wire should run from the C2 terminal to the C1 ter-

minal to the P1 terminal to the P2 terminal (See Figure 50 on page 128).

Note the average error in the measurement. Adjust the C0K parameter by

subtracting the measured error. For example, if the input is exactly 0.0Ω

and the readout shows –0.11Ω, adjust the C0K parameter by adding

0.11.

Connect a 10 kΩ resistor (25 ppm accuracy) to the input and measure its

resistance. Note the average error in the measurement. Adjust the C10K

parameter by subtracting the measured error. For example, if the input is

C10K parameter by subtracting 2.95.

Connect a 100 kΩ resistor (25 ppm accuracy) to the input and measure

its resistance. Note the average error in the measurement. Adjust the

C100K parameter by subtracting the measured error. For example, if the

input is exactly 100.0000 kΩ and the readout shows 99.9913 kΩ, adjust

the C100K parameter by adding 8.7.

4. Record the date in the DATE parameter and set the DUE parameter to

the desired calibration interval.

9.2.2

Calibration Procedure

Calibration of each channel is performed in two steps. First the voltage mea-

surement is calibrated then the internal RJC is calibrated. The equipment re-

quired are a programmable voltage source, a precision voltmeter with an

accuracy of 10 ppm or better, a thermocouple (preferably type E), and a tem-

perature source between 0 and 30°C. The combined accuracy of the reference

thermocouple and temperature source must be 0.06°C or better between the ref-

erence temperature and ambient temperature. At each step during the calibra-

tion procedure the readings should be allowed to settle for at least two minutes

before recording the measurement. Also, the 1529 should be allowed to warm

up for at least one hour after power up prior to calibration. The recommended

procedure is as follows:

1. Connect the voltage source to the thermocouple channel, set it for 0 mV,

and measure the voltage with the 1529 and the voltmeter simultaneously.

Adjust the C0 parameter by subtracting the measured error. For example,

if the 1529 measures –0.0006 mV, adjust the C0 parameter by adding

0.0006. If it was previously 0.0000 it should now be 0.0006.

2. Set the voltage source to 100 mV and measure the voltage with the 1529

and the voltmeter simultaneously. Adjust the C100 parameter by sub-

tracting the measured error. For example, if the input is exactly 100.0000

mV and the 1529 shows 100.2953 mV, the C100 parameter should be ad-

justed by subtracting 0.2953. If it was previously 0.0000 it should now

be –0.2953.

3. Verify the voltage accuracy at 0, 50, and 100 mV. The accuracy must be

within the short-term voltage accuracy given in the specifications.

4. Connect the calibrated thermocouple to the thermocouple channel and

insert the thermocouple into the temperature source. Measure the tem-

perature with the 1529 (be sure to program the channel with the correct

thermocouple type). Adjust the CRJ parameter by subtracting the mea-

User’s Guide

sured error. For example, if the thermocouple temperature is actually

0.0°C but the 1529 reads 0.184°C, the CRJ parameter should be adjusted

by subtracting 0.184. If it was previously 0.000 it should now be –0.184.

6. Record the date with the DATE parameter. Set the DUE date to the de-

sired calibration interval.

7. Repeat the procedure for any other thermocouple channels.

10 Maintenance

Maintenance

• The calibration instrument has been designed with the utmost care. Ease

of operation and simplicity of maintenance have been a central theme in

the product development. Therefore, with proper care the instrument

should require very little maintenance. Avoid operating the instrument in

oily, wet, dirty, or dusty environments.

• If the outside of the instrument becomes soiled, it may be wiped clean

with a damp cloth and mild detergent. Do not use harsh chemicals on the

surface, which may damage the LCD or the plastic front panel.

• If a hazardous material is spilt on or inside the equipment, the user is re-

sponsible for taking the appropriate decontamination steps as outlined by

the national safety council with respect to the material.

• Before using any cleaning or decontamination method except those rec-

ommended by Hart, users should check with an Authorized Service Cen-

ter (see Section 1.3) to be sure that the proposed method will not damage

the equipment.

• If the AC adapter becomes damaged, have it replaced immediately. Never

disassemble the AC adapter or attempt to repair it.

• If the instrument is used in a manner not in accordance with the equip-

ment design, the operation of the thermometer readout may be impaired

or safety hazards may arise.

• Periodic calibration of the instrument at regular intervals is required to en-

sure that it continues to measure with proper accuracy. Calibration should

only be performed by qualified authorized personnel.

11 Troubleshooting

Troubleshooting

In case you run into difficulty while operating the 1529 system, this section

provides some suggestions that may help you solve the problem. Below are

several situations that may arise followed by possible causes and suggested ac-

tions you might take.

11.1

Troubleshooting

The following table lists possible error messages, their causes, and suggested

actions.

Problem

Incorrect temperature reading

Solution

While attempting to measure temperature, the display shows an incorrect value or no value at all

( . . . . . . . . . ).

• If the temperature readings seem to be incorrect you should first check to see if the

resistance, or voltage in the case of thermocouples, is being measured correctly.

Set up the display to show the resistance or voltage for the channel.

• If the resistance or voltage is incorrect refer to the next subsection for troubleshoot-

ing incorrect resistance or voltage readings.

• If the resistance or voltage is being measured correctly but the displayed tempera-

ture value is incorrect consider the following possibilities:

One or more coefficients are incorrect. This is a common mistake. While entering coefficients

it is easy to miss a digit or sign. Check all the values carefully using the EDIT PROBE function

(see Section 7.2.1) comparing them with the values on the calibration certificate for the probe.

Use the TEST PROBE function to test the coefficients (see Section 7.2.1.10, Standard Thermo-

couple Conversions).

The selected conversion type is incorrect. Check to make sure the correct conversion type is

selected. In the case of thermocouples, make sure you have selected the correct type. You

should also make sure that you have selected the proper reference junction compensation (RJC)

made for your application (see Section 7.2.1.10, Standard Thermocouple Conversions). You

can use the TEST PROBE function to test the temperature conversion calculation.

The measurement is out of range. The 1529 may not be able to calculate temperature accu-

rately if the resistance or voltage is outside the valid range. The measured resistance or voltage

may be too low or too high if the actual temperature is too low or too high or if there is a problem

with the sensor.

• The measure period may be set to a long interval. Check the measure period set-

ting.

Problem

Solution

Incorrect resistance or voltage

reading

While attempting to measure resistance or voltage, the display shows an incorrect value or no value at

all

(. . . . . . . . . . ).

Consider the following possibilities:

Poor or incorrect connection of the probe. A common mistake is to connect the wires of the probe

to the wrong terminals. Check the wiring carefully, especially when using a four-wire PRT (see Section

6.4.1). Make sure the lead wires are fastened down tightly.

Open, shorted, or damaged sensor or lead wires. In the case of resistance sensors check the resis-

tance across the sensor using a hand-held DMM. Also check the resistance between common pairs of

leads. Check to make sure there is no conductivity between any of the leads and the probe sheath.

Use a good-quality sensor to avoid errors caused by drift, hysteresis, or insulation leakage. In the case

of thermocouples, use a hand-held DMM to check its voltage.

Improper setting for three or four-wire probe. Make sure the correct wiring type is selected Select-

ing three-wire input while using four-wire probes may cause errors of 0.01 to 0.1 ohms. Selecting

four-wire input while using three-wire probes will result in erratic or out-of-range readings (see Section

7.2.1.1).

Electrical interference. Intense radio-frequency radiation near the 1529 or probes can induce noise

into the measurement circuits resulting in erratic readings. The 1529 is intended to operate in a labora-

tory environment with limited radio-frequency noise. If interference seems to be a problem you might

try eliminating the source of interference or moving the 1529 to a different location. A well-grounded,

shielded cable should be used for the probe leads.

Stem conduction error. The problem may be that the actual temperature of the sensor is not what

you expect. This is often the result of stem conduction where heat flowing through the stem of the

probe to ambient affects the temperature of the probe. It is very important that probes be inserted to an

adequate depth into the material being measured. Measuring temperature using a surface sensor can

be especially difficult as the sensor is directly exposed to ambient.

Wrong calibration parameters. The problem may be that the calibration parameters for the 1529 are

invalid. Check the parameters currently stored in the unit against those listed on the 1529 Report of

Calibration.

Blank screen

The screen lights up when the 1529 is switched on but the screen appears blank. This problem

can be caused by improper adjustment of the contrast. After the power is switched on allow the 1529

at least one minute to complete its self-test and power on sequence. Then, try to adjust the contrast

using the contrast buttons.

Error message at power up

The 1529 reports an error during the power up self-test. On power up the 1529 performs a series of

self-tests to check the operation of all its components and each of the modules. The results of the

self-tests are reported on the screen. Normally, all tests report ‘OK’. Below is a table of error messages

and recommended actions to correct the error. Often these errors can be corrected by completing the

actions listed. A failure of one or more component causes error messages to be reported. Component

failures generally require a qualified factory technician to replace the faulty component. Contact an Au-

thorized Service Center (see Section 1.3).

Temperature not

updating

The 1529 measure period may be set to a long interval. Check the measure period.

Frequently Asked Questions

11.4.1

Battery

1. What type of batteries does the Model 1529 use? The Model 1529 uses a

built-in Nickel-Metal-Hydride battery pack.

2. How long do I need to charge the battery initially? The batteries come

fully charged. If for some reason they are not fully charged, the front

panel indicator shows this and you can recharge them as needed.

3. How long does the battery take to fully charge? About 3 hours from

fully discharged.

4. How long does the battery last from full charge? About 8 hours from

full charge with the backlight off.

5. How do I know when the battery is at full charge? The charging indica-

tor LED located on the back panel displays amber while charging and

then turns green when the batteries are fully charged (only when the AC

adapter is connected). The front panel indicator at the bottom right

shows when the batteries are in use and their approximate charge state.

6. How does the backlight affect the battery life? With the backlight on low

the battery life is reduced by 25%, medium by 30%, and high by 40%.

7. Do I have to let the battery fully discharge before charging? No, the bat-

teries do not need to be fully discharged before recharging. You may re-

charge them at any time.

8. Is it recommended that I allow the battery pack to fully discharge occa-

sionally? In order to maintain the charge/discharge characteristics of the

139

1529 Chub-E4 Thermometer Readout

User’s Guide

battery, Hart recommends that you allow the battery to discharge com-

pletely once a month. You do this by allowing the Model 1529 to operate

on battery power until it shuts down on its own.

9. If I allow the battery pack to fully discharge, what happens to the calibra-

tion parameters stored in the Model 1529? Parameters used by the Model

1529 are stored in non-volatile RAM (NVRAM). This IC stores the pa-

rameters even when power is not applied.

10. How many recharge cycles is the battery good for? Approximately 500.

11. What happens to my measurement accuracy when the battery is low?

The Model 1529 does not display temperature when there is not suffi-

cient power to make a correct measurement.

12. If I am using the autolog and the battery runs out will I lose my data?

No, you won’t lose any data. The Model 1529 simply stops logging

data. When the AC adapter is plugged in, the data logging continues.

13. How do I dispose of the batteries used in the Model 1529? Disposal

guidelines can be found by consulting your local governing authority.

14. If the AC adapter is plugged in and I have the unit turned on, is the bat-

tery still charging? Yes, the Model 1529 charges while in use without af-

fecting the charging time or its performance.

15. If I am using the Model 1529 with AC power and a power outage occurs,

will the batteries automatically take over? Yes, when AC power is re-

moved from the Model 1529 for any reason, the batteries automatically

supply back up power without risk of losing any data.

11.4.2

Input

1. Can I swap out measurement boards in the field? No, the measurement

boards were not designed to be exchanged in the field.

2. What are the implications of the fast measurement mode in terms of ac-

curacy? Accuracy is reduced when using the Model 1529 in fast mea-

surement mode. Refer to Section 8.1.1 for a better description of the fast

measurement mode and its limitations.

3. Why can I only see one channel in the fast measurement mode? Because

of the time required to make a measurement and update the display, there

is not enough time to display more than one channel when in the fast

measurement mode.

4. Do I have to reprogram the Model 1529 each time I swap out a probe?

In addition to the four main channels, there are nine memory locations

available to store probe coefficients. If the new probe’s information has

been programmed into one of these locations, you can copy it to the

channel to which it is connected.

5. How does the moving average affect the data that is logged? The data

collected by the Model 1529 is stored as it appears on the display. If you

Frequently Asked Questions

set the Model 1529 to average the measurements, the data it logs reflects

the moving average setting.

6. How many probe coefficients can I store? Thirteen. Four sets in the

main channels and nine sets in memory locations.

7. Are the readings really simultaneous in the simultaneous mode? Yes.

There are four measurement circuits that collect the raw data simulta-

neously. The raw data is then converted to its corresponding temperature

in sequence taking less than 0.5 seconds for all four channels.

8. How does the three-wire RTD setting affect my overall accuracy? When

using the three-wire setting in the Model 1529, a partial compensation of

lead-wire resistance is performed as per normal industry practices. Since

a three-wire measurement can’t fully compensate for lead resistaance,

accuracy is reduced. As stated in the specification section of this manual,

you need to add 0.05Ω to the measurement accuracy plus the maximum

possible difference between the resistances of the lead wires.

11.4.3

Logging

1. How many data points can the Model 1529 store? You can store up to

100 demand log readings and 8,000 autolog readings.

2. What happens when the log memory is full? Logging stops once the

memory is full. Readings are not deleted to make room for new readings.

3. How can I tell when the log memory is full? Full memory is indicated in

the log stats function in the logging menu. You can also program a field

in the lower display to show the autolog memory status.

4. Can I use the Model 1529 for other applications while I am autologging?

Yes, the Model 1529 can be used while logging. However, keep in mind

that the channels that are displayed are also logged. Changing the chan-

nels affects the data that is logged.

11.4.4

11.4.5

Output

1. How do I get data from the Model 1529 to my PC? Data can be trans-

ferred to your PC via an RS-232 interface.

2. Can the Model 1529 be set to simultaneous measurement mode and log

to the serial port? Yes. The Model 1529 makes the measurements simul-

taneously and transmits them to the serial port. However, most printers

can’t print as fast as the data is logged so it doesn’t appear to be

simultaneous.

Other

1. Can I update the Model 1529 firmware without sending in my unit? Yes.

Firmware updates include a utility program that installs the upgrade via

the RS-232 port.
