Operating Instructions
Exacta®2 Digital Torque Wrenches
Safety
•Never use these tools for anything other than their designed purpose.
•Never use these tools beyond their rated capacity.
•Always wear and use appropriate safety equipment when operating these tools.
Modes of Operation - General
The Exacta®2digital torque wrenches have three modes of operation: Track, Peak and Residual.
In the Track mode functions similarly to a dial or beam torque wrench. The current torque is shown on the
display as it rises or falls in response to the force applied. This can be particularly useful when working with
fasteners having a prevailing torque feature (crimping or insert) and for fastener testing.
In the Peak mode, the torque is shown on the display as it rises, and when the force applied to the tool
declines the maximum torque applied before the decline is retained on the screen for a period of time and
stored in memory. This mode is exceptionally useful in assembly operations and some testing operations.
This mode may be used with or without torque specifications having been programmed into the tool.
The Residual mode is designed specifically to capture the torque remaining on a fastener after it has been
installed and tightened. The theory behind this is that when testing the torque remaining on a fastener after
installation, the torque applied to the fastener will rise until the fastener begins to move. When the fastener
begins to move there will be a brief reduction in the torque followed by another rise in the torque. The
bottom of this temporary reduction in applied torque is interpreted as the Residual torque. It must be noted
that this works best on hard joints with stiff fasteners. For joints where this mode works well, the wrench
makes an excellent auditing tool.
S/R Dovetail and Interchangeable Heads
Those models of the Exacta®2digital torque wrench that are equipped with an S/R dovetail are designed
to be used with S/R interchangeable heads. The dovetail design provides an exceptionally strong and rigid
connection.

Sturtevant Richmont - Exacta®2- Page 2 of 20
The Exacta®2 models with the dovetail are calibrated for use with S/R
interchangeable heads having a 1 7/16” Common Centerline Length
(CCL). Use of interchangeable heads with a different CCL or head
extension(s) will make the tool inaccurate until and unless it is recalibrat-
ed with a head having the same CCL as that which has been selected
for use. Always recalibrate the tool immediately if changing to a head
with a different CCL or if a head extension is to be used.
Ratchets
Some Exacta®2 models have ratcheting square drives instead of the
S/R dovetail. These are slide pin ratchets capable of being set
to ratchet in either the clockwise (CW) or counter-clockwise
(CCW) direction. To change the ratcheting direction, remove all
torque load from the tool and push the slide pin to the opposite
side from that to which it is currently biased.
The ratchet should be disassembled, cleaned and lubricated
periodically. The procedure for performing this function can
be found in the FAQ section of our website. See the Ratchet
Replacement procedure (FAQ 7) and simply clean and replace
the original parts instead of installing new parts. If the ratchet
is damaged, contact your S/R distributor and order the correct
ratchet renewal kit for your tool, then use the instructions on
the website to perform the replacement.
Battery and Battery Charger Selection
The Exacta®2 digital torque wrench has very specific battery requirements that must be adhered to. Only
batteries meeting these requirements may be used.
•Use of any batteries other than those provided by S/R or meeting the specifications on the Batteries

Sturtevant Richmont - Exacta®2- Page 4 of 20
10. Indicators
There are four triangular indicators in a line across the top of the display. These indicators are activated
and deactivated to show what mode or operation is currently active on the tool. To the right of these is a
battery icon (not activated in this photograph) used as a battery level (low battery power) indicator.
11. Unit of Measure Area
This area of the display shows the currently active unit of measure, both during use and during
keyboard programming.
12. Data Record Area
This small four-digit display shows the currently-active data record in memory or, when programming,
part of the function information required.
13. Quality Attribute Area
There are several icons along the bottom of the display to the left of the Data Record area. These
include “OK” and “BAD”, which provide the attribute evaluation of the torque against the programmed
specification when the tool is in use. They also include MAX and MIN
14. CCW Icon
The CCW icon illuminates when the torque is in the counter-clockwise direction.
15. Primary Display Area
The primary display area conveys differing information depending upon the current action of the tool.
This may be numeric information such as torque values or alphabetic information such as is used in
some programming and communication functions.
16. Rear LED Lens
This lens illuminates with the color (Yellow-Orange/Green/
Red) in the same manner as the display when the LED color
system is in use. This permits the user to know the status of the
tightening even when the tool is used in an orientation where the
display is not immediately visible.
17. Buzzer
This buzzer provides an audible indication of the torque status to
augment the visual indicators. When in use, the buzzer emits a
single sound when power to the tool is enabled, a rapid series of
beeps when the torque specification is attained and while within
the specification. It will emit a single longer beep if the torque specification is exceeded.

Starting Routine
To use the wrench slide the power switch to the Enabled or On position. The tool will begin an internal start-
ing routine and the display will first show the version of the firmware that resides on the tool then display
the model of the tool (tool capacity in foot-pounds).
Once the starting routine is complete, the tool will then show on the display the information for the status in
which it was most recently set. This includes the mode of operation, unit of measure, current data record
number and target torque setting.
Normal Operation - Definition
The phrase “normal operation” will be used in several locations in these instructions. The definition of “nor-
mal operation” is the condition where the tool is being used as a torque wrench and not currently connected
to a computer. Data operations are treated separately.
On-Wrench Programming
The four buttons on the keypad may be in a locked or unlocked state. This section applies when the key-
pad is in an unlocked state. For information on locking and unlocking the keypad, see the section on using
the tool with the Exawin 5 software.
Many, but not all, of the functions of the Exacta®2digital torque wrench may be programmed using the
four buttons on the wrench keypad if the keypad is unlocked. Those that can be programmed from the key-
pad are: Unit of Measure (UOM), Minimum (Lo) Torque Specification, Maximum (Hi) Torque Specification,
and Mode of Operation (Track, Residual or Peak).
Exacta®2 uses a single-level menu to access the primary functions, and scrolling to move through the op-
tions within the functions. To program the tool, follow the steps in this section.
1. Activate power to the tool by sliding the power switch to the enabled (On) position.
2. Allow the unit approximately five seconds to complete
it’s internal starting routine and self-checks.
3. When the starting routine is complete, the normal
operating mode screen will appear about as it does
here during normal operation.

Sturtevant Richmont - Exacta®2- Page 6 of 20
The large number in the center is the Target, or the midpoint value between the minimum and maximum
(Lo and Hi) torque values currently active on the tool. The active Target arrow verifies this.
The current Unit of Measure is displayed beside the large numbers, in this case Foot-Pounds. The ar-
row below the Peak indicator shows that the unit is in Peak mode of operation. The data record displays
the data point or record that will be the next one recorded.
There are four buttons forming a keypad to the right of the display. These buttons are used in the pro-
gramming of tool functions and for reviewing torque data stored on the tool.
4. To begin programming the tool, press the SELECT button twice.
5. The Unit of Measure is the first item to be
programmed. The current UOM is displayed. Press
the Up arrow button to scroll through the available
units of measure. When the desired unit of measure
is displayed, press the Select button once to
make it active and advance to the next item to be
programmed.
6. The next menu item is the Minimum (Lo) Torque
Specification. The appearance of “-Lo-” in the Data
Record area of the display confirms this is the current
programming function. The current specification value
will be displayed, in this case zero foot-pounds. You
can press the “Clear” button to set the minimum and
maximum values to zero.
To increase the minimum torque specification value, press the Up arrow button once. The value will
increase by one. Each time the button is pressed the value will increment by one.
To increment rapidly, press and hold the Up arrow
for two (2) seconds. The value will start rising
rapidly. Release the button when the desired value
is displayed. If the desired value is missed, use
single pushes of the Up or Down buttons to obtain
the desired value. For this example, the minimum
torque value is forty (40). The yellow “Caution”
color will become active at 90% of this value when the tool is in use; the green “Good” color will be
displayed when this value is attained. The green color will remain until either(1) cycle is complete or
(2) the Maximum Torque Specification is exceeded or (3) tool capacity is reached. Press the Select
button to lock in this value and move to the next function. Note: When the minimum torque value is set,
the maximum torque value is set to the same point to permit more rapid programming of the maximum
value.
7. The next function is the Maximum (Hi) Torque
Specification. The Data Record area of the display
will show “-Hi-” to indicate this function is active. The
center numbers will display the current maximum
torque value. This specification value can be changed
to zero if desired by pressing the Clear button.

Sturtevant Richmont - Exacta®2- Page 7 of 20
The Up button is used to increment the value upwards. The increment is one (1) for each press of the button.
If the specification is wide, increasing the value rapidly can be performed as it was on the Minimum
Torque Specification selection; press and hold the Up button for two (2) seconds to begin rapid
incrementing. The Up and Down arrows can be used to set the final value if it is missed while being
rapidly increased. Press the Select button to lock in the desired value and move to the next item.
8. The tool will advance to the Mode of Operation screen. There are three (3) modes of operation
available, each with its’ own screen symbology. The modes and symbols for each are:
“otrA” = Track Mode, torque rises and falls with force
applied. No data is stored.
“oPEA” = Peak Mode, highest torque captured with
each use; the store and print/clear processes are
used if the autoclear time is greater than zero.
“orES” = Residual Mode, used for auditing torque
on installed fasteners. The auto-store/print/clear
process is used if the autoclear time is set to greater than zero.
When the symbol for the desired mode of operation is displayed, press the Select button to make it
active and advance to the next menu item.
The “data” screen is not part of normal operation. It is used to transfer data, and will be covered in a sepa-
rate section of this document.
To leave programming of the tool and begin normal operation with it, press the Select button one time. The
display will show an active indicator under the indicator label for the current mode, an active indicator for
the target torque, the unit of measure selected, the target torque, and the currently active data record. The
tool is now ready for use in torque application.
By default, both the LED color scheme and the beeper will be active. These cannot be programmed or
altered through use of the keyboard programming method.
Programming and Data Collection Using the Exacta®2 with S/R Exawin 5 Software
S/R offers Exawin 5 software that may be used to program the wrench and as a data collection tool. This
software is available for free on the S/R website when you register your Exacta®2. The software is not
required in order to collect data from the tool; the tool is capable of creating a self-generated report when
used with Hyperterminal or other terminal software on a computer. Exawin does, however, provide a rapid
and simple method for obtaining data from the tool.
The serial cable supplied with the wrench may be used to connect the tool to the computer. If the computer
does not have a 9-pin serial port, a powered serial to USB convertor (S/R part no. 10456) is available.
To connect the computer running Exawin 5 to the tool:
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.

Sturtevant Richmont - Exacta®2- Page 8 of 20
4. Enable power to the tool (turn tool power on).
5. Allow the tool to complete its’ starting routine.
6. Start the Exawin 5 software on the computer. Follow the software instructions for using the software
with the tool.
7. When complete, disconnect the tool from the serial cable.
Uploading Data from Tool to Computer Using Hyperterminal
Hyperterminal (or another terminal emulation program) may be used with the Exacta®2 digital torque
wrench to collect the torque data stored on the wrench. The process for doing this is:
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.
5. Set the communication protocols within Hyperterminal to the following settings:
Baud Rate = 1200 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, and that none will be placed on it during this process.
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 image here.
7. Look at the “Data Record” number on the tool display. The data record number that is on the display
should be one record number higher (larger) than the last record number you wish to upload to the
computer.

Sturtevant Richmont - Exacta®2- Page 9 of 20
Example: There are three torque records on the tool, and the Data Record shows “0003”. You wish to
upload all three torque records. With the display showing “0003”, only two records would be uploaded.
To upload all three, the display must show data record “0004”.
Use the Up or Down button to index to the number of records you wish to upload + 1.
8. Press the Select button to enter and page through the menu until “dAtA” is displayed on the main
section of the display.
9. To begin sending the information to the computer, press the Down button on the tool. This will
cause the information to be sent to the computer. In Hyperterminal, the information will be displayed
approximately as it does in the image immediately below.
The structure of the data record string is:
Torque Direction, + is clockwise, - is counter-clockwise
Numeric value of torque
Unit of measure of the torque
Torque Mode
Compliance to programmed specification (OK or BAD attribute)
Tool record number
Tool Serial Number
16-Character User-Definable String (set using Exawin 5)
Minimum Programmed Torque Specification
Maximum Programmed Torque Specification
Date of Record
Time of Record
10. To clear the uploaded data from the tool memory, press the Up button on the tool and allow the
clearing process to finish before going to the next step. If you wish to retain the data currently on the tool,
just go to the next step.
11. To exit the data transfer process, press the Select button on the tool. This will return the tool to nor-
mal operation.
12. Save, print or transfer the data in the Hyperterminal program using the program’s menu functions.
13. Exit the Hyperterminal program and disconnect the serial cable from the tool.

Using the Exacta®2 - Normal Operation
Once the tool has been programmed to the torque mode, unit of measure and torque specifications
desired, the tool is ready for use. The display will show the target torque (mid-point between minimum and
maximum torque specification values) in the primary section of the display. The triangle below the Target
indicator will be illuminated, as will the triangle below the torque mode (Residual or Peak). The unit of
measure will be displayed, and the current active data record will appear in the lower right-hand corner of
the display.
Grasp the tool by the grip, engage the fastener to be tightened (or item to be torqued) and begin applying
torque using a steadily-increasing force. When you attain approximately 90% of the minimum torque value,
the display and rear LED lens will illuminate with a bright yellow-orange light to warn you that you are
approaching the specified torque.
When you achieve the minimum specified torque the illumination will change from yellow-orange to a bright
green, and rapid beeps will be emitted from the buzzer. Stop applying force immediately.
The torque value (peak or residual) for that use of the tool will remain on the display for two seconds
(default value). The “OK” icon will also illuminate, as will the triangle for Stored. The information will be
stored in memory, the displayed value will then change back to the target torque, and the data record
number will increment by one.
If you inadvertently apply more torque than the maximum specified value, the display and rear LED lens
will illuminate with a bright red color, a single long beep will be emitted by the buzzer, and the BAD icon will
illuminate. This combination will exist for two seconds (or user-defined time) before the value is stored and
the tool indexes and resets for the next tightening.
Stored values from prior uses (tightenings) can be viewed and can be written over. To view a prior value
during normal operation, simply press the Down button to scroll down (decrement) to the data record of
interest. During this you may also press the Up arrow to scroll up (increment) to a record of interest. Re-
member to return to the correct data record number since the tool will record the next torque in the record
active when the tool is used.
If a torque is to be eliminated before being written to memory, press the Clear button before the Autoclear
time expires. This clears the display and the just-completed value is discarded and not written to memory.
This ability to scroll also permits ready correction of an error in torque application. Assume that in tighten-
ing a series of fasteners a slight overtorque occurs on the 7th fastener - data record 0007. After the display
clears, the active data record is 0008. To correct this immediately:
- Press the Down button to return to data record 0007.
- Use the tool to loosen the fastener. This will cause the tool to record that torque and again index to
data record 0008.
- Press the Down button to return again to data record 0007.
- Correctly tighten the fastener. This will produce a correctly tightened fastener and a record of the
torque to which it was tightened.
The tool will store up to 999 data records. Once all the data records are filled, the tool continues writing
subsequent torques in the 999 location.

Sturtevant Richmont - Exacta®2- Page 11 of 20
Calibration
The calibration process for the 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

Other Serial Communications Commands and Communications
The serial communications system used by these tools permits flexibility in terms of tool operation control,
data transfer and tool operation. Some, but not all, of the these options are available readily through the
Exawin software.
Some of the functions covered in this section are only available through the use of Hyperterminal or similar
terminal software, such as changing the baud rate used by the tool to communicate with the computer.
All commands incoming from the tool end in a carriage return and a line feed. All commands going out to
the tool must end with a carriage return. In this section the carriage return keystroke will be represented by
“<cr>’.
Available Tool Baud Rates and Considerations
These tools may communicate at any of the following baud rates: 1200, 2400, 4800, 9600, 19200, 38400,
76800, 115200. The default baud rate is 1200, and when the tool is connected to the computer this rate is
used until and unless the baud rate is changed by sending a command to the tool to change the rate.
The default rate works well in two respects; it does not take a lot of time to transfer data for small or medi-
um quantities of records, and it is highly reliable. Higher baud rates are available to expedite the upload of
large quantities of records, and each increase in speed provides a commensurate decrease in upload time.
Increased baud rates do come at a cost in reliability for these serial communications just as they do with
other serial communications. These tools use a “broadcast” approach; the information is sent and there is
an assumption that it was properly received. There is no checksum or other “error-proofing” methodology
used. Since error rates (both transmission and reception) increase as the baud rate increases, there is an
increased likelihood of communication error when using higher error rates. The error rates are the same for
1200 and 2400 baud, but begin to creep slowly higher as the rate increases.
Note also that when you first enable power (turn on) to the tool, the rate will be 1200. If you send the com-
mand to a higher baud rate, you must then also set the terminal software to communicate at that rate. Note
that after the tool is disconnected and the power disabled, it will revert to the default rate. To re-establish
communication the terminal software will need to be reset to the default rate.
The command to set the baud rate to a different level is “Bb” followed by a <cr> (Enter). In this
command, the lower-case “b” is replaced by the number representing the rate to be used for subsequent
communications.
The table for the number and represented baud rate:
1 2400
2 4800
3 9600
4 19200
5 38000
6 76800
7 115200
Other All other characters set baud rate to 1200

Set Time/Date Stamp
These tools have an internal clock that can be reset with the time/date stamp. The format of the stamp
(U.S. Standard or European Standard) used in the time/date stamp can also be selected. The default is the
U.S. Standard method of reporting this information.
The command to set the time/date stamp is “@”.
To set the time and date when the U.S. format is used, the command will be structured as:
@UMM/DD/YYYY,HH:MM:SS<cr>
Example: @U12/05/2009,13:45:30<cr> would set the date and time as 12/05/2009 13:45:30
To set the time and date when the European format is used, the command will be structured as:
@UDD/MM/YYYY,HH:MM:SS<cr>
Example: @U05/12/2009,13:45:30<cr> would set the date and time as 5/12/2009 13:45:30
Clear Current Tool Data (Partial)
This command uses “CL” followed by <cr> to clear the data records stored on the tool up to the current
record number.
Clear Current Tool Data (All)
This command uses “CLA” followed by <cr> to clear all the data records stored on the tool.
Set Data Report Format
This command allows the user to change the tool-generated report by dropping fields from the data sent by
the tool to the computer. The default setting is to send all data in each record, and this was shown earlier
by a screen capture. Users not wanting the data in one or more fields may instruct the tool to omit these
fields from the transmitted information.
Note that the deletion of fields will be effective for all transmissions to the computer until either another
change command is sent or the tool is turned off. Users with access to programmers or programming skills
may construct scripts that will manage this function using this and related commands.
The command = “TX00000000000000” followed by <cr> sets the data report format to the default of
reporting all fields when the report is generated. Replacing any “0” with a “1” for that field tells the tool to
omit that field in the data sent to the computer.
The field sequence is that shown in the first image on the following page.
There are 14 bits between the “TX”, but only 11 fields, counting the carriage return and line field, in the data
record. The other three bits define the items not particular to an individual data record but pertinent to the
report itself. These items are bits numbered 11, 12, 13 and 14 in the table on the following page.
Bit 12, the “User Defined String” is an accommodation to customer requests pertinent to use of these
tools with Exawin software. The User Defined String in Exawin allows the user to have a 16-character
alphameric identifier (tool number or name) of the user’s own creation and assignment. This line appears in
the top section of the report (above the record data) when this item is printed.

Sturtevant Richmont - Exacta®2- Page 19 of 20
Bit 13 causes the number of records in the report to be printed or not printed. This is true whether the
report includes all of the records on the tool or only a subset of them. This item is printed above the data
record section of the report when the report is printed.
Bit 14 allows the user to choose to keep the comma separation default for field delineation or to switch to
tab delineated separation.

Frequently Asked Questions
Can I modify the light scheme?
Yes. There are several ways to use the Warn/Good/Overtorque light scheme.
If you program the tool from the keypad with a maximum torque specification only, the yellow-orange
Warning and green “Good” colors will not be used. The LED will illuminate red for Overtorque (and
overload) if the maximum torque specification (or tool capacity) is exceeded.
If you program a minimum torque only, the LED will illuminate with green for torque above the minimum,
there will be no warning illumination, and the red illumination will occur only if the tool is overloaded.
If you program neither a minimum nor a maximum torque specification, there will be no LED illumination
unless tool is loaded above capacity.
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.
