Care and Storage
When not in use the unit should be returned
to the supplied carry case.
The membrane keypad may be wiped clean
with a soft damp cloth. The unit is not water-
proofed and spillages should be avoided.
This unit is designed for indoor use only

5-40 degrees C
THIS UNIT CONTAINS NO USER SER-
VICEABLE PARTS. ONLY QUALIFIED
SERVICE PERSONNEL SHOULD
REPLACE OR FIT PARTS.
Storage temperature range

Battery Charging
The batteries in the ETA unit are shipped
fully charged.
Fast Charge
The ETA’s should only be recharged with the
supplied ETA-BC (Model MPP3OUS12) Bat-
tery Charger. ETA’s, are supplied with inter-
nal NiMH (Nickel Metal Hydride) batteries.
These are environmentally friendly batteries
presenting no problems for safe disposal
and are capable of sustaining a rapid
recharge. From fully discharged, the unit will
require a charging period of approximately
2.5 hours.
In continuous use with a transducer con-
nected, the batteries have a life of at least 8
hours.
With the unit switched off from a 10% charge
state, the batteries will fully discharge in 25-
50 days. To prevent the loss of all setup
data, the unit has additional battery backup
for the internal memory.
Automatic Power Off
To charge the batteries following a period of
use, connect the supplied charger to the
charging socket on the back of the unit and
plug the charger into a suitable supply. The
green LED will come on to indicate the
machine is charging and will start to flash
when the unit is fully charged. If the red LED
comes on, this means there is a problem
and usually indicates a faulty battery.
To conserve battery life in use, the unit will
switch off automatically after a predefined
period. Pressing the on key will restore the
unit to the last display prior to powering off.
The Fast Charge method gives an increase
in the effective life of the charged batteries.

Barcode read input for characteristic
names and comments
It is possible to scan a barcode name in ETA5 at certain prompt lines. The input of a barcode is
allowed at the characteristic name prompt in store characteristic, direct characteristic and edit
characteristic modes. In addition it is also possible to scan a barcode in the comment field in
store characteristic only. Edit characteristic and normal store behave in a slightly different man-
ner to direct characteristic. The ETA5 will accept most barcode reading formats, but not all.
General Operational Method for Scanning Bar Code Data
Connect the Bar Code Reader ETA-BAR to the Printer/PC connector at the rear of the ETA5.
Barcode readings can generally be taken at the prompt to input data (Characteristic name or a
comment) when the flashing cursor is on the screen. This can be on a blank line or following a
line of data (an existing characteristic or a comment). When the cursor is flashing, scan the
code with a barcode reader and observe the screen. If the flashing cursor disappears, the code
has been captured - wait a few seconds for the data to appear in the display. If the flashing cur-
sor remains, re-scan the code until it is accepted.
Enter
When the data is displayed, press
as for normal data input.
to continue. From this point, follow the instructions
When entering data via the Bar Code Reader into a comment field, make sure you have
reserved enough characters in the comment field to accept the code. If the number of charac-
ters scanned in exceeds the number reserved, the ETA5 will beep and refuse to accept the
data. Refer to the instructions on Configuration for more details.

Notes on Password Protection:
Be aware of the implications of password protection. Always keep a note of the chosen
password somewhere safe. As there is no function to enable an existing password to be
removed without it first being entered, it may be advisable for the person who is ultimately
responsible for the ETA to initially set a password and issue it only to personnel who need the
information. This will prevent an unknown password being entered, accidentally or deliberately,
without anyone else’s knowledge. If an unknown password is encountered, please contact
Ingersoll-Rand for advice.

Rotary and Stationary Joint Kits
Introduction
The joint kits are designed as a convenient, repeatable, variable stiffness joint for assessing the
performance of torque tools. They can be used with the Ingersoll-Rand stationary (static) or
rotary transducers.
Each kit may be assembled in different ways to vary the stiffness of the joint. Reference Table 1,
to select from the available options. Care should be taken to ensure that the maximum torque
for the joint is not exceeded. Please note that the joint kit is not designed to provide an exact
joint stiffness and that the rates shown in Table 1 are given as rough guide only.
Joint Assessment
The first task is to choose the stiffness of the joint that the tool will be used to assemble. This is
best done with a torque wrench on an actual production part. If available an angle measurement
protractor may be used, but this is not essential. Tighten the fastener until it is snug, note the
torque Ts in Nm (or lbft). Tighten to the required target torque Tf Nm (or lbft), and note the angle
of rotation E in degrees. The required joint stiffness may now be calculated. The resulting units
are degrees per Nm (or degrees per lbft).
E / (Tf-Ts)
Ts = Snug Torque
Tf = Target Torque
E = Angle
It should be noted that for packaging convenience Joint Kits will be delivered assembled with full
stacks of belleville washers. The spacers will be bagged separately. The Joint Kits DO NOT
represent a usable joint without adjustment to the required stiffness. A Pictorial guide to the
description of components is shown in Figure 2. Table 2 shows the parts available for each
model.
Joint Assembly
Having selected the required joint stiffness from Table 1, count out the number of Belleville
washers required for the first and second stacks. Grease each washer and assemble the first
stack around the bolt, such that the internal diameter rests against the shoulder of the bolt.
Invert the second stack such that the outside diameters of the last and first washers in the two
stacks touch. If only one stack is to be fitted, it should be mounted such that the external
diameter rests against the bolt shoulder. Select and fit the spacer required to complete the joint.
After greasing the bearing surface, slide the assembly into the external sleeve, fit the end collar
and secure by applying the retaining clip.

7529_eng.fm Page 52 Wednesday, November 12, 2003 8:57 AM
The base plate or transducer, depending on model, should be mounted onto a rigid surface.
See Figure 1 for bolt hole pattern. Place the bolt assembly just completed into the shroud and
then onto the transducer or base plate. The last step is to apply the steel washer onto the bolt
before applying the nut.
IMPORTANT - Grease the threads and fit the nut.
- Ensure that the threads are kept clean and lubricated.
The joint is now ready for use. Eventually the bolt and nut threads will wear and will need to be
replaced. IR recommends replacing worn joints with the appropriate bolt kit that matches your
joint kit model: JKS30-BKIT, JKS150-BKIT, JKS300-BKIT or JKS1000-BKIT.

Glossary of Terms
Characteristic
Cp
Specification of one particular torque value to be collected. Each
characteristic has a name of up to 14 characters. ETA5 can store up to 48
different characteristics at any one time.
This is a capability index which shows the process capability potential but
takes no account of how centred the process is. This is used for capability
studies and Cp may range in value from 0 to infinity. A large value indicates
greater potential capability and a value of 1.33 or greater is desirable.
Max -- Min
Cp =
6
(Max and Min are limit values)
CpK
This is an index which indicates whether the process will produce units within
the tolerance limits. If the process is centred on the nominal value then CpK
will have a value equal to Cp. For values of CpK between 0 and 1 then some
of the 6 sigma spread will fall outside tolerance limits but for values greater
then 1 these will all be within tolerance. A negative value of CpK indicates
that the process mean is outside tolerance limits. A value of 1.33 or greater is
desirable.
(Max -- x )
3
( x -- M i n )
3
CpK = lesser of
or
(Max and Min are limit values)
CAM
This is an alternative capability index requiring a minimum of 30 readings to
be taken. In this implementation, 5 sub-groups of 6 samples are used for
each calculation. The CAM calculation uses the following formula:
Max -- Min x Cam Factor *
6 x Average Sample Value
* CAM Factor is taken from a table
(in the case of 5 x 6 samples = 1.910)

High Output Transducer (H/O)
Torque transducer with no coding links but internal pre-amplifier giving an
output signal level of typically 1 or 2 volts.
Horizontal Sampling
Collection of data by round, taking one reading for each characteristic in turn.
Industry Standard Transducer (I/S)
Type of transducer, with no pre-amplifier or coding links, but with the exact
rated torque, marked on the body.
Master Round
A sequence of up to five rounds. It is used to allow a collection sequence,
which is part vertical, part horizontal.
Max Torque Value
Upper tolerance level of any reading. This can equal but not exceed the
torque rating of the transducer to be used.
Min Torque Value
Lower tolerance level of any reading.
No. of Sub Groups
Number used to allocate memory space in ETA, for a particular characteris-
tic. May be set in the range of 1 to 99.
Round
A sequence of characteristics to be collected either horizontally or vertically.
Each round has a name of up to 14 characters.
Sample
Individual torque reading.
Standard Deviation σ
Is a measure of the variation of the samples of a statistical group. If a group
of ‘n’ values has a mean of ‘x’ then its standard deviation is given by:

7529_eng.fm Page 57 Wednesday, November 12, 2003 8:57 AM
Sub-Group
Grouping of samples to enable analysis, with an allowable range of 1-50.
Threshold Torque Value
Level of torque in which a signal must rise above and then fall below to be
considered a valid torque cycle. This may be set in the range of 1 to 50% of
rated span or the Min Torque Value, whichever is the lower.
Units of Measure
It is possible with ETA to read a transducer calibrated in for instance, Nm,
and convert internally to display and store in any of the other torque units.
Vertical Prompt Collection of data by round, where a full sub-group is collected for a char-
acteristic, before stepping to the next characteristic.
Vertical Plus Prompt
Identical in procedure to that of Vertical mode except that before stepping to
the next characteristic, ETA5 will prompt for the fitting of a transducer (even
though the correct one is installed) and will require the ENTR key to be
pressed. Stepping to the next characteristic, ETA5 will prompt for the fitting of
a transducer (even though the correct one is installed) and will require the
ENTR key to be pressed.

circuitry may be reset by linking pins 5 and 6 in the PC connector, with a length of wire. This
will turn the unit off. Turn the unit on again by pressing ‘ON’. If after this reset ETA still fails
to operate correctly, use ‘6’ for Miscellaneous and ‘6’ Software Reset to clear memory.
Having carried out a hardware reset as described above the message ‘800 MEMORY’
may be displayed on the next power up, and a software reset should be carried out.
