Battery Installation
At the end of the grip is a battery cap that covers the battery compartment inside the grip. To install the
batteries:
1. Insure that the correct batteries are those to be used, and
that they are completely charged. Follow the instructions
that come with the charger to charge the batteries before
installing them.
2. The battery cap is screwed into an internal thread inside
the grip. Remove the battery cap by unscrewing it from
the grip (CCW).
3. The battery compartment will be exposed. There are two
labels inside the compartment. Install the batteries in the
locations given by the labels and maintaining the battery
orientation shown by the labels and in the photo here.
4. Reinstall the battery cap. Tighten the cap only to snug; do
not overtighten the cap.
The 3000-Series Exacta®2has a Low Battery Indicator on
the display. If the battery voltage falls below 4.1 volts, a
battery icon will appear in the upper right-hand section of the
display, the “BAD” icon will illuminate and “bAtt” will be displayed in the main display. When this occurs it
is time to replace the batteries. Wrench will continue to operate until the battery voltage drops below 4.0
volts. At that time the display will show the message “bAtt” and the ability to operate the wrench will be
lost. Readings stored prior to that point will remain in memory. The tool will remain inoperable until the
batteries have been replaced with charged batteries.
Interchangeable Heads
The 3000-Series Exacta®2 digital torque wrenches of 150 foot-pound capacity and below use the S/R
dovetail system. The tools are calibrated for use with S/R Interchangeable Heads having a 1 7/16” Common
Centerline. Any S/R heads with this centerline length may be used without affecting torque accuracy. If an
interchangeable head of a different centerline length is to be used, the tool must be recalibrated with that
head (or one of the same centerline length) before the tool is used.
The 400 foot-pound capacity tool is calibrated for interchangeable heads having a Common Centerline
length of 3 7/8”. When used with heads having the same Common Centerline length, no recalibration is
needed. If a head with a different Common Centerline length is to be used, the tool must be recalibrated
before use with an interchangeable head of the same Common Centerline length as the one to be used.
3000-Series Exacta®2 digital torque wrenches of 250 foot-pound capacity and above (except 400 ft. lb.)
use S/R slide pin ratchets. The ratchets should be disassembled and cleaned periodically. Ratchet renewal
kits having the appropriate parts for each ratchet are available.

Power Switch, Serial Port and Cover
On the top of the electronics housing are the power switch and serial port for the tool. These are protected
by a rubber that can be lifted to expose them for use. The cover should be closed at all times when access
to the serial port and/or power switch is not immediately
needed.
The tool power is enabled (power On) by sliding the switch
away from the grip as shown here. Power to the tool is
disabled (power Off) by sliding the power switch towards the
grip.
The serial cable for the wrench connects to the round serial
port that is also used to hold the cover in place. The cable
should first be connected to the computer (9-pin connector)
then to the tool (single-pin connector) when the tool is to communicate with the computer and software.
Display Elements
Text Indicators and Triangular Icons
There are four words of text above the LCD. Each of the words: Target, Residual, Peak, and Stored has a
triangular icon underneath it along the top of the LCD. The icons are used in conjunction with the values in
other areas of the display. Note: The display will vary slightly from the depiction here due to differences in
the fonts used.
Target
When the triangular icon beneath this is illuminated, it means that the target value for the torque
specification is displayed in the main section of the display. The target
value is the midpoint between the minimum and maximum torque
specification values.
Residual
When the triangular icon beneath this is illuminated, it means that the
Residual mode is the current torque measurement mode.
Peak
When the triangular icon beneath this is illuminated, it means that the Peak mode is the current torque
measurement mode.
Record
When the triangular icon beneath this is illuminated, it means that the specific record in the lower right-
hand corner of the display is being reviewed and the torque for that record is the torque value currently
displayed.
Unit of Measure Indicator
Available units of measure include inch-pounds, foot-pounds and Newton metres. The current unit of mea-
sure is displayed to the right of the main section of the display.
Main Section
The main section of the display is used to display a variety of information important to the current function-
ing of the tool. During normal use, the target torque or the current torque will be displayed, depending upon
whether the tool is awaiting use or actually tightening a fastener. The triangular icons and text along the top
indicate which value is being displayed.

Sturtevant Richmont - P/N 857285 - Issue Date 100407 - Page 4 of 14
Other Icons
There is a battery icon in the upper right-hand quadrant of the screen above the units of measure. This icon
and other indications are used to warn the user when the battery voltage drops to a level where the batter-
ies should be replaced.
There are two icons used in normal operating mode (during performance of a task) to provide a quality at-
tribute indication for a just-completed fastener. The “OK” and “BAD” icons are located along the bottom of
the display on the left side. When a torque application is completed and the final torque result is compared
to the torque specification values for the task, an attribute evaluation is made and the appropriate icon is
illuminated briefly.
Definitions
Target A specific torque value: the midpoint between the minimum and maximum torque specifi-
cation values for the task.
Peak Mode of operation capturing the highest torque value in a single loading of the wrench.
Residual Mode of operation for capturing the torque remaining on a previously-installed fastener. In
this mode the tool captures the lowest point between two peaks; the peak torque to begin
fastener motion (includes inertia) and the peak torque where force application stopped.
Stored Mode of operation used to review torque values currently stored on the tool.
Task A set of from 1 - 50 torque applications grouped together and sharing common unit of
measure and torque value specification. Tasks are numbered from “00” to “50”.
Record A single torque application within a specific Task. Numbered from “00” to 50. Record 00 is
designed to give the user the ability to use the specifications for the active task on a
fastener without recording the result.
UOM Currently active Unit of Measure for torque. IN.LB, FT.LB, Nm
Clear Button Clear the current reading from the display and, if in a task or record other than “00”, begin
storing information at the current point.
Select Button Used to enter, select, and exit various options on the tool itself.
Up Button Used to move (increment) upwards among options and increment levels within a selected
option.
Down Button Used to move (decrement) downwards among options and increment levels within a
selected option.
Task 00 A special task always available, even when specific tasks have been downloaded to the
tool. When Task 00 is displayed, the tool functions as a torque wrench with no memory of
the torques applied, similar to a beam or dial wrench. When there is no job on the tool,
the default settings for the tool will be applied.
Yellow Light Color (orange- yellow) projected onto display to indicate that the warning torque level has
been reached during use and that the speed of force application should be slowed. Use
of the LED color scheme is selectable in the software (active or inactive). Warns user that
the torque specification is being approached. Used in all Tasks numbered 01 and above
when record 01 and above are active. Not available in “Task 00” or “Record 00”.
Green Light Color projected onto display to indicate that the current torque is within the limits of the
minimum and maximum torque specified for that Task. Use of the LED color scheme is
selectable in the software (active or inactive). Active in all Tasks numbered greater than
“00”. Not available in “Task 00” or “Record 00”.

Sturtevant Richmont - P/N 857285 - Issue Date 100407 - Page 5 of 14
Red Light Color projected onto display to indicate that the current torque exceeds the maximum
torque specified for that Task. Use of the LED color scheme is selectable in the software
(active or inactive). Active in all Tasks numbered greater than “00”. Not available in “Task
00” or Record “00”.
Keypad
The keypad to the right of the display has four buttons: Clear, Select, Up and Down.
Clear The Clear button is used to clear a reading from the tool and make that Task/Record combination
the active combination for the next torque application. Example: The operator makes an error in
tightening the fastener. The operator returns to the correct record within the task for that record,
then presses the Clear button. This clears the display of the reading and displays the target
torque, as though the operator were facing that fastener for the first time. The operator may then
properly tighten the fastener and store the torque value for the retorque where the original value
was stored.
Select The Select button is used to navigate among tasks. During normal (job loaded) operation, press
the select button once to permit navigation among the tasks currently on the tool. Use the Up and
Down buttons to navigate to the task to be performed. Press the Select button again to make that
task the active task. Note that when so doing it is necessary to use the Up and Down buttons to
navigate to the record of interest after the task has been selected.
Up Navigate among tasks and records. Increments count of displayed task or record by one.
Down Navigate among tasks and records. Decrements count of displayed task or record by one.
Display During Operation
Exacta® Plus uses a liquid crystal display and a buzzer to communicate. The display content is grouped
into four categories: items displayed during startup when the power is turned on, items displayed during
PC communications, items displayed during normal operation, and items displayed when results are being
reviewed.
Items Displayed During Startup
1. The tool series number “3000” will be displayed in the center, and “r00N” in the Task and Record
markings will be displayed for 1 - 2 seconds. “N” is the firmware revision number.
2. The tool capacity will be displayed in the center for 1 - 2 seconds.
3. Upon completion of the startup routine, what is displayed is dependent upon whether or not there
are tasks in the memory of the tool
If no Tasks are in memory, the following will appear on the display:
Indicator for the Peak mode will be lit.
Indicator for Target will be lit.
IN.LB Unit Of Measure will be lit.
-000.0 will be displayed as the current torque value.
00 will be displayed for the Task number.
00 will be displayed for the Record number.
If one or more Tasks are in tool memory, the following will appear on the display:
Indicator for the active mode will be lit.
The indicator for the active Unit Of Measure will be lit.
The Target torque will be the displayed torque value.
The number of tasks in memory will be displayed in the Task section.
After startup the last task and record number worked on will be displayed. If the tool memory has
been cleared, the task and record will each be “00”.

Tool Use Without Job Download
The 3000-Series tools can be used to a limited extent without downloading a job. The tools have default
factory settings of inch-pounds as the unit of measure, Peak as the mode of operation, and no data
capture in memory. When no job has been downloaded, these default instructions are active.
The tool can be used to measure torque in inch-pounds, to observe the torque during the application, and
to briefly (2-3 seconds) display the peak torque once it has been achieved. The data for the use will not be
stored in memory and available for later use.
Connecting the Tool to a Computer and Using Exacta Plus Software
Use the supplied serial cable to connect the tool to the computer that has the Exacta Plus software
installed.
1. Ensure that the computer has the power enabled and is operating.
2. Connect the 9-pin end of the supplied serial cable to the serial port of the computer.*
3. Ensure that power to the tool is disabled (Power Switch in Off position).
4. Connect the single-pin end of the cable to the serial port on the tool.
5. Enable power on the tool.
6. Start the Exacta Plus software.**
* If the computer has a USB port but does not have a 9-pin serial port then a powered USB to RS-232
converter will be needed. S/R offers one as P/N 10456.
** The Exacta Plus software may be started before this step if desired. There is no need to close the
software before connecting the tool if the software is running on the computer.
When the tool is connected to the computer and the Exacta Plus software is being used to communicate
with it, avoid touching the buttons on the tool and do not disable the power. Allow the software to perform
the communications and complete them before taking further action with the tool.
The software will perform all of the functions required to assure communication with the tool as long
as the tool is properly connected, the power is enabled, and the correct communication settings for the
computer and software have been selected and are used. If there is a communication problem check the
communication setting first; instructions for this are provided with the software. If there are still problems, it
is likely that the connectors on the cable are not properly seated at one end or the other. Check the cable
connections to determine which is incorrect or incomplete and correct the problem with the connection.
During the download the display will update as each task is downloaded. The displayed values will
include the mode of operation, unit of measure and target (midpoint between minimum and maximum
specifications) as the task is received and stored. When the download is complete, the information
pertinent to the last task downloaded will be on the display.
Once a job has been downloaded from the software to the tool and the download has been confirmed as
successful by the software, close the active communication window(s) on the computer. The tool can now
be disconnected from the cable. The same applies when uploading data on a job to the computer.
Normal Operation
When the download was completed, the information on the last task received in the download is on the
display. If there is more than one task in the job it is necessary to make the first task to be performed the
active task.

Sturtevant Richmont - P/N 857285 - Issue Date 100407 - Page 7 of 14
• To navigate to the desired task, press the Select button one time. The word “SEt” will appear in the main
section of the display. The task number of the last task downloaded will be in the Task section display.
• Use the down arrow to scroll through the task numbers until the desired task number appears.
• Press the SEt button a second time to make that the active task. The display will show the unit of
measure, mode and target value for this task.
• The record number will be “00”. To change the record, press the Up button one time to go to the “01”
record. Once this is displayed, the tool can be used and recording will start at the first record.
As you start applying torque to the first fastener, the main section of the display will change from the target
torque to the current torque value. When you reach the Warning Torque for the task, an LED will backlight
the screen and light the lens with a yellow-orange light to alert you that you are approaching the specified
torque. When the minimum torque specification is achieved, the illumination will change from yellow-orange
to bright green, and the beeper will emit five rapid pulses.
Stop the force application and remove the tool from the fastener. The torque for that fastener and the task
and record number for it will remain on the screen for three seconds. The tool will then turn off the LED
and index to the next fastener in the task (if more than one). This inform/warn/record/inform/index cycle will
repeat until all of the fastening records for that task have been obtained.
Once the last fastener in a task has been completed, the information will be displayed normally, then the
screen will display “SEt” in the main section.
Use the Up arrow key to go to the next task in the sequence. When the desired task is displayed, press the
Select button again to make this the active task. The tool will be in the “00” record; press the Up button to
go to the first fastener in the task.
At any time when the tool is not applying torque you can leave the current task and move to a different task
by using the Select button. At the new task you can use the tool in the “00” mode or you can select the
fastener(s) in the task to be tightened and use the tool normally.
Correcting an Error
If you make an error in a torque application and wish to correct it and the record for that fastener, this can
be achieved easily. There is a slightly different method to be used if the torque was too low than if it was
too high.
If the torque was too low:
1. Use the Select, Up and Down buttons to navigate to the applicable task and record.
2. When the correct record is displayed, press the Clear button.
3. Use the tool to apply the correct torque. This will store the new data where the old data was. You can
then navigate to the next task and record to be worked on.
If the torque was too high:
1. Use the Select, Up and Down buttons to navigate to the “00” record for that task.
2. Loosen the overtorqued item.
3. Use the Select, Up and Down buttons to navigate to the applicable task and record.
4. When the correct record is displayed, press the Clear button.
5. Use the tool to apply the correct torque. This will store the new data where the old data was. You can
then navigate to the next task and record to be worked on.

Uploading Data
To upload data, connect the serial cable from the computer to the tool and use the software to perform the
upload function. If communication errors are encountered, check the security of the cable connections and
the computer communication settings.
Communication Default Settings
The default settings for serial communications are: 9600 Baud, 1 Start Bit, 8 Data Bits, 1 Stop Bit.
Calibration
The calibration process for the 3000-Series Exacta®2tools has three sub-processes. The first is testing
the tool to find the “as found” condition. If the tool is out of calibration, then two subsequent processes are
performed; calibration adjustment to bring the tool into calibration, and subsequent repetition of tool testing
to assure that the adjustments were effective and the results are valid. This process addresses only the
adjustment, not pre- and post-adjustment testing.
We strongly recommend that when performing the calibration process a torque tester of not less than
0.25% Indicated Value Accuracy be used, and that it be used in conjunction with a mechanical loader to
obtain proper loading of the tool. We have designed these tools to be as hand-position insensitive as we
can within other constraints, but the use of a mechanical loader is still recommended. The load applied
during testing must be at the loading point on the grip indicated by the plain ring at the middle of the grip.
It is imperative that when calibrating and testing one of the tools having the S/R dovetail that the calibration
be performed with an interchangeable head having the same Common Centerline Length as the head the
tool will be used with. Changing the Common Centerline Length does change the readings and using the
incorrect head will result in torque inaccuracy.
We strongly recommend that the tool be temperature stabilized before testing, and that fresh batteries
be used during the procedure to assure that the tool does not suffer a loss of battery power during the
process.
This section of this document presents the information required to make adjustments when the tool is found
to be out of tolerance.
Needed items (in addition to tester and loader):
• A computer with a serial port and Hyperterminal software
• The serial cable supplied with the torque wrench
Setup for Adjustment
1. Ensure the computer is operating and that tool power is disabled (off).
2. Connect the serial cable to the serial port on the computer.
3. Connect the single-pin connector on the cable to the serial port on the tool.
4. Start the Hyperterminal software on the computer. Note: Most versions of Microsoft Windows include
Hyperterminal sofware. Other terminal emulation software programs will also work for this procedure.

Sturtevant Richmont - P/N 857285 - Issue Date 100407 - Page 9 of 14
5. Set the communication protocols within Hyperterminal to the following settings:
Baud Rate = 9600 baud (tool default baud rate at startup)
Data bits = 8
Stop bit = 1
Parity = None
Flow Control = none
6. Ensure that there is no torque load on the tool. Enable power to the tool and allow it to complete the
starting processes. Communication with the computer will be established and the tool will send the
firmware version and model information to the computer. In Hyperterminal, the information will appear
approximately as it does in the next image.
7. Type the diagnostic “D” Command into the terminal and press <enter>. The Terminal display will dis-
play “DiaOn”. You are now in diagnostic mode.
8. Type the M <enter>. The capacity of the tool should be seen on the display.
9. To enter the Calibration process, press the ‘Select‘ button on the tool keypad.
Calibration Procedure Keypad Functions

Frequently Asked Questions
The display turned red and showed “OL”. What happened?
The tool is designed to be used within its rated capacity, and one of the calibration points for the tool is the
100% of capacity point. The tool is not designed to be used above this point.
At approximately 106% of capacity we use the LED and show “OL” on the display to tell the user that the
rated capacity has been exceeded and that the tool is in danger of being damaged. Even a single use
above this level can cause the tool to become less accurate, and repeated use at this level increases the
probability of accuracy degradation and expensive damage to the tool.
At approximately 120% of rated tool capacity there is a very high probability of damage to the sensor,
including damage of a level that necessitates replacement.
We strongly recommend that the tool never be used beyond its rated capacity, and that if the tool is
inadvertently overloaded it be immediately removed from service and the calibration checked.
During the starting routine I saw “CAL” and 0 (or -0) appear on the display. What does this mean?
During the starting routine the tool checks the calibration table against the output from the sensor. This
message appears if the two are not in agreement. Most frequently this is a response to an overload of the
sensor (and tool) to the point where the sensor has suffered a deformation.
If this occurs the tool should not be used. Have the tool calibrated, and repaired if necessary, before use.
