USER GUIDE
Introducing the ChartReader
For product code and serial number information please refer to the bottom label of your ChartReader.
Multiple Downloads
The ChartReader Memory versions EJ-CR-II, EJ-CR-MEM, MN-CR-MEM, EA-CR and EI-
CR-MEM support Multiple Downloads. This means more than one logger data set can be
downloaded to, stored in, and printed from the ChartReader. This feature allows the
ChartReader to be used in an application where there are multiple loggers in the field.
Each logger can be downloaded into the ChartReader (stored as a ‘data block’) and then
printed out at a later more convenient time or downloaded to a PC using the ChartReader
Interface.
The ESCORT user software has the ability to download the saved ‘data blocks’ (loggers
that have been download into the ChartReader) from the ChartReader and process them
just as if the logger had been placed on an interface connected to the PC. Thus the User
software is able to list, graph, and save them.
Note: Multiple download is enabled by default. To disable this feature please use the
ESCORT user software and select ‘N’ to the ‘Enable Multiple Downloads’ option in the
configuration settings (refer to the ESCORT software user manual and help menu).
Logger Variants
All variants in the Junior product range except Junior General Purpose Loggers are
supported by the Junior ChartReaders with 1MB flash memory (EJ-CR-II and EJ-CR-
MEM). Junior loggers with extended memory (40K) cannot be read by EJ-CR and EJ-CR
16.
The iLog ChartReader supports all versions of ESCORT iLog data loggers, including
humidity loggers.
The MINI 2000 ChartReaders MN-CR and MN-CR-MEM support all versions of the MINI
2000 logger.
The Intelligent ChartReader EA-CR supports all versions of the Intelligent Mini and
Wireless Mini logger.
Easy To Upgrade
Future upgrades to the ChartReader can be done via software. This will allow future
variants in the product range to be easily supported by your ChartReader just by
uploading new firmware via the ESCORT firmware loader software (provided by your
distributor upon request).
Battery Check Function
ChartReader can tell you when it needs to have its battery charged. After selecting the
Battery Check option the ChartReader will check, measure, and print the results of a
battery condition test. This will give you an indication of the current battery condition
before you take it out into the field.

Latest CPU Technology
The ChartReader incorporates the technology of a new breed of high performance 16bit
microprocessor with more on board memory.
Flash Memory Version
The low memory versions (EJ-CR, EJ-CR-16, MN-CR) store logger data information in
RAM and will therefore lose currently stored logs if the battery fails before the user prints
the logger information (or downloads the information to a computer system). This should
not be a problem since the user can check the battery status at any time.
However the latest ChartReaders are equipped with 1MB (1,000,000 Bytes) flash memory
(EI-CR-MEM, EJ-CR-MEM, MN-CR-MEM, EA-CR). This allows approx. 700,000 to
800,000 readings from multiple loggers to be stored. FLASH memory allows the
downloaded readings to be retained even if the battery fails. Once the battery is charged
or external power is provided, the readings can be printed as normal.

Overview of ChartReader Keys
Turning On Your ChartReader
To turn your ChartReader on, press the ON button on the ChartReader’s keyboard. Note that
this button also acts as CANCEL, OFF, and is part of all advanced key combinations. The
indicator light above the ON key will alight when the ChartReader is activated.
Reading Data from a Logger
To read a Junior or iLog data logger, slide the logger into the ChartReader’s attached
interface and press the read button. For reading a MINI 2000 or Intelligent Mini logger, plug
the ChartReader to logger interface MN-CR-INT or EA-CR-INT delivered with the
ChartReader into the logger and the ChartReader. The indicator light above the button will
slowly flash during the read process and a series of beeps should be heard from the logger or
ChartReader (depending on model). At the completion of the read, the ChartReader sounds a
beep and the indicator remains ON.
The reading process takes between 30 seconds to several minutes depending on the amount
of logged data stored in the logger. Once the data is read, it is stored as a ‘data block’ in the
ChartReader’s memory until deleted by the user through the user software or by pressing the
correct key combination on the ChartReader. If the ChartReader cannot communicate with
the logger, the indicator flashes more rapidly, and a series of long beeps are sounded.
Chart Printing
To print a chart (or graph) of logged data, press the chart key.
This will print from the latest data block stored in memory (the last logger read).
The chart is created according to internal ChartReader specification (see options) and
typically scales the graph either to the full range of the logger’s sensor(s) or to the upper and
lower specifications retrieved from the logger. The ChartReader will print approximately 4000
readings in three minutes so an 8000 readings chart will take 6 minutes to print. Chart printing
a humidity logger (EJ-HS-B) may take longer due to humidity calculations.
Printing out of Specification Readings
To print a list of out of specification readings press the “out of specification” button.
This will print from the latest data block stored in memory (the last logger read).
The printout lists all readings outside the upper or lower specifications retrieved from the
logger. Users also have the ability to configure their ChartReader to print out all of the
readings via ESCORT Console software.
Re-Arming Loggers with a Magnetic/Button Start
By pressing the re-arm button of the ChartReader, will stop the logger’s current program
status and set up the logger for magnetic/button start.
Logging parameters are unchanged (i.e. number of logs, logging interval, specification etc).
The ChartReader beeps at completion to indicate successful re-arming. If the re-arm is
incomplete or unsuccessful the ChartReader will sound a long beep and flash the indicator
above the re-arm button. The rearm feature can be disabled using the ESCORT user
software.

Advanced Key Combinations
+
Printing Data Block Summary
This will print a summary showing the memory status (bytes free and used) and the number
of data blocks that are currently retained. Each data block contains the data that was
downloaded from a logger.
+
Printing Data Block and List Summary
This will print a list of all data blocks stored in memory showing:
- the data block number,
- the serial number of logger the data block is for,
- and the first few characters of the description for that logger.
The last logger read will be stored in the data block with the highest data block number.
+
Battery Check
This will check the condition of the battery and print the results. The precise battery voltage is
also printed out during the test. This allows you to use previous experience in judging the
battery condition. The following table shows available conditions:
Condition
Excellent
Good
OK
Fair
Action
Do not charge the battery.
Ready for general use.
Ready for light to medium use.
Should be charged.
Poor
Definitely charge before using.
NOTE: If the test starts to print then stops without producing the correct test summary then
the battery definitely needs charging.
+
Deleting the Last Data Block
This will delete the last data block in memory. This allows memory to be freed and/or previous
data blocks to be accessed for printing.
Note: Although some ChartReaders can store a large number of data blocks they should not
be used as an archive (a place to permanently store readings from loggers). Once a data
block has been printed and/or downloaded to a PC via the ESCORT user software it should
be deleted. Doing so will increase the overall speed performance of the ChartReader.
In addition, you are only able to delete all of the data block via the ESCORT Console
software. You can manually delete each data block via the ChartReader one record at a time.
CAUTION: Once a data block is deleted it cannot be retrieved!

L Multiple Downloads - Example
The following is an example of how to use the multiple logger download feature of the
ChartReaders with 1MB FLASH memory. The example is based on a warehouse with several
cool rooms that are furnished with one logger each to record the temperature. On a regular
basis the graph or out of specification readings have to be printed.
Note: Multiple downloads is enabled by default. To deactivate this feature please use the
ESCORT user software and select ‘N’ to the ‘Enable Multiple Downloads’ option in the
configuration settings (refer to the help menu).
Example
+
1. Perform a battery check by pressing the
keys. The battery condition should
be OK or better. If not then the battery should be charged before proceeding.
+
2. Print a data block summary by pressing the
keys.
3. If there are data blocks stored in memory then delete them by pressing the
+
keys. If there are more than one data block to be deleted, the
key can
be held down and the key repeatedly pressed on and off until all the data blocks are
deleted. After each data block is deleted the ChartReader will produce a single beep.
When there are no more data blocks left to delete the ChartReader will produce a series
of beeps.
4. Now the ChartReader is ready to be used in the warehouse. For each logger :-
4.1. Make sure the ChartReader is turned ON (the active indicator light will be ON if
the ChartReader is turned ON ).
4.2. Connect the logger to the ChartReader interface and press the
key. The
ChartReader will download the logger’s readings into a data block.
4.3. At this time the logger’s readings could be printed out via pressing the chart
key or out of specifications key.
4.4. If required the logger could be re-armed (programmed anew) by pressing the
key. This would stop and set up the logger for a magnetic start with the same
logging parameters as before.
4.5. Remove the downloaded logger from the ChartReader interface, and if it was re-
armed place it where required and swipe the start magnet across the logger.
(
+
)
4.6. At any stage a data block summary
or data block list
(
+
)
can be printed out to verify which loggers have been downloaded.
+
5. At a convenient time/place print a data block list with the
show you the order of how the loggers where stored in your ChartReader.
6. The last data block is always the one that is active for printing. So if it needs to be printed
in chart form or out of specifications only then press the or keys respectively.
7. Once the data block has been printed, delete it by pressing the
CAUTION: Once a data block has been deleted it can not be retrieved. Pressing the
keys. This will

USER GUIDE
Powering & Charging the ChartReader
The ChartReader contains an internal NiCad battery which typically, when fully charged, can
provide power for about 1 hour of continuous printing.
To charge the NiCad battery, plug a 12V @ 1A supply into the DC connector located at the
rear of the case. The plug needs to be a 2.1mm DC plug with negative on the inner
connection.
(An adapter of lesser current rating (i.e. say 0.7 amp) can be used but this will increase the
time it takes to fully charge the battery.) A 12V car cigarette lighter adapter can also be used.
When connected to a suitable power supply, the ChartReader will indicate that the battery is
being charged by flashing the ON light.
The battery will normally take up to 2 hours to fully charge with 90% of the charge being
attained within the first hour. The charger can be left permanently plugged in without damage
to the ChartReader or battery.
Sometimes the battery will not take on a fast charge and the ON light will stop flashing well
before 1 hour is elapsed. In this case the ChartReader will continue to charge the battery in a
“trickle charge mode” and may take up to 18 hours to fully charge a battery.
Note: It is highly advised that the battery is fully exhausted before recharge to
maximise life and capacity of the battery.
Note that because the ChartReader uses an intelligent charge technique, it cannot be turned
off when external power is applied (i.e. a charger is connected). As soon as the external
power supply is plugged into an inactive ChartReader, it will automatically turn on to maintain
the charging of the battery.
Power Failure
The battery will typically exhaust itself during printing as this is the most energy consuming
activity. When the battery is becoming exhausted, the ON indicator will rapidly flash and a
beep will be sounded. If this occurs during printing (the most likely time) the printing will
pause until either the battery voltage rises or a charger is plugged in.
To continue using the ChartReader, plug in an external power source. As long as the printing
was not aborted it will automatically continue once a suitable external power supply is
attached.
