Operating and Service Manual
1200-Series Exacta ® 2 Digital Torque Wrench
www.srtorque.com
NOTE:
This tool requires the use of rechargeable NiMH AA batteries. Using ANY other type of battery immediately
voids the 1-year limited warranty on this tool. The electronic circuit of the 1200 Series was designed to save
power and operate on 1.2 volts. NiMH AA batteries are designed to provide ONLY 1.2 volts. AA Alkaline
batteries provide 1.5 volts and therefore can damage the electronics.
Tool Overview:
SR 1200-Series Exacta® 2 Digital Torque Wrenches are designed to work with the Global 400 and Global
400mp process monitor/process monitors. These are the first digital torque wrenches with wireless
capability that are designed for industrial assembly use. The wrench is completely dependent on the Global
400/400mp for directions and torque results reporting. Once connected to the Global 400/400mp, the
wrench keypad is disabled.
These tools are designed for ease of use. Operators simply pull to green, there are no buttons to push.
The display and audible signal the operator of the status for each tightening. The display and Fresnel
turn yellow when approaching minimum torque. The display turns green with an audible beep when
target torque is achieved. Exceeding maximum torque causes the screen to turn red and the audible
beep changes to one long tone.
*Details on programming the tool through the Global 400/400mp process monitors are found in the
process monitor manual and "how to" videos at www.srtorque.com. The 1200-Series Exacta 2
does not communicate with the Global 8.
Safety: Always wear appropriate personal safety equipment when operating this tool.
□ Never use this tool for any purpose other than that for which it is intended.
□ Never use the tool beyond its’ rated torque capacity.
□ Never immerse the tool in liquids.
Battery and Battery Charger Selection
The Exacta® 2 digital torque wrench has very specific battery requirements.
• Use of any batteries not meeting SR NiMH AA rechargeable battery requirements could
electronically and physically damage the tool and immediately void the warranty.
• BATTERY CHARGING NOTE: The first time you charge NiMH batteries the batteries should remain
charging for at least 24 hours. Removing the batteries from the charger prior to 24 hours shortens
battery life and the number of cycles a battery can power in the wrench.

The correct replacement battery pack (NAFTA countries only) for tools in the Exacta® 2 digital torque
wrench line is SR part number 21258. This pack includes four (4) AA NiMH 2000 mAh batteries.
For countries outside NAFTA, follow the battery manufacturer websites regarding NiMH 2000 mAh AA
rechargeable batteries and select the appropriate product for your country.
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. NOTE: When brand
new batteries are used for the first time please leave
them on the charger for 24 hours prior to use. Even
though the charger may indicate the battery is charged,
premature battery use shortens battery life. 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 until snug; do
not overtighten the cap.
The 1200-Series Exacta® 2 has 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 or
recharge 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 fully charged batteries.
Interchangeable Heads
The1200-Series Exacta® 2 digital torque wrenches of 250 foot-pound capacity and below use the SR
dovetail system. The tools are calibrated for use with SR Interchangeable Heads having a 1 7/16”
(36.5mm) Common Centerline. Any SR heads with this centerline length may be used without affecting
torque accuracy.
The 400 foot-pound capacity tool is calibrated for interchangeable heads having a Common Centerline
length of 3 7/8” (98.4mm). Any SR heads with this centerline length may be used without affecting torque
accuracy.
There are two 1200-Series Exacta® 2 digital torque wrench models that come equipped with a fixed
ratchet. The 250 foot-pound capacity and 600 ft. lb. The ratchets should be disassembled and cleaned

periodically. Ratchet renewal kits having the appropriate parts for each ratchet are available. Contact
your local SR sales professional to order or visit www.srtorque.com.
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 cover that can be lifted to provide access to the power switch. The cover should be closed at
all times.
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 that is supplied with the wrench connects
to the round serial port that is also used to hold the cover in
place.
Component Identification
1. Electronics Module
The electronics module houses and protects the circuit boards, display, operating buttons and other
electronic components.
2. Display
The display conveys the visual information needed for use and generated by use.
3. Indicator Labels
These labels, working with indicators on the display, inform the user what mode or function is currently
active.
4. Buttons
These buttons (Clear, Select, Up, Down) are used only for calibration purposes.
5. Grip
The grip is where the tool should be grasped when in use. The load point on the grip is marked by the
plain ring in the center of the grip.

Sturtevant Richmont - P/N 857317 - Issue Date 161024 - Page 4 of 14
*Points 6-9 do not apply to this model.
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 of 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 during use.
12. Data Record Area
This small alpha/numeric four-
character display shows the
firmware version upon power
up. When in radio contact, it
displays “rAd”, if the tool is not
connected to a Global
400/400mp, displays “bAd”.
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 used
during calibration. If the screen is dim and this area is all dashes,
(- - - -) the tool is in suspend mode.
16. Rear Cover
The rear cover permits access to the electronics when repair is
required; it should not be removed except for repair situations
requiring its’ removal.

Sturtevant Richmont - P/N 857317 - Issue Date 161024 - Page 5 of 14
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 speci fication. It will emit a single longer
beep if the torque specification or torque capacity is exceeded.
18. Rear LED Lens (Circular, #16 in image on previous page)
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 notifies the user of the tightening status even when the tool is used
in an orientation where the LCD display is not immediately visible.
Wrench Electronics Starting Routine
To use the wrench, slide the power switch (9) to the Enabled or On
position. The tool will begin an internal starting routine and the display
will fi rst show the Series Number of this Exacta 2 wrench. The display
will show 1200. In the lower right hand corner of the display you will
see the tool firmware number. The display then shows tool capacity in
foot pounds. The radio serial number is the third item for display. This
completes the initial start-up screen sequence.
Once the initial start-up sequence is complete the wrench moves to suspend mode. In suspend mode the
screen dims and the screen shows a horizontal dashed line where the torque values normally appear.
If the tool has been associated with or learned by a Global 400 or 400mp, the lower right-hand corner of
the display will have the characters “rad” active. If the radio has not been associated with a Global 400 or
400mp, the lower right hand corner of the display will read “bad”.
Association or Learning Process with the Global 400/400mp
Each Global 400/400mp and the different types of SR branded wireless tools use a XBEE transceiver.
Each transceiver has its own unique address. Once a tool is associated to a Global 400/400mp they will
only communicate with each other. To change a tools location within a facility and connect that tool to a
different Global 400 the tool must be erased from the original Global 400/400mp.
Associating a 1200 Series Exacta 2 with a Global 400/400mp is fast and easy. See the Global
400/400mp owner’s manual for details and processes.
Using the Tool with the Global 400
Once the tool and process monitor radios are connected, the tool must be assigned to a parameter
before it can be used. See Global 400/400mp owner’s manual for complete details.
Performance NOTE:
SR 1200-Series Exacta® 2 Digital Torque Wrenches are NOT designed to be used without a Global 400 or
Global 400mp. The only time this tool can be operated without a process monitor is during calibration. During
calibration the 1200 Series wrench must have the radio disabled.
When the tool is used with a Global 400, the keypad is locked. This is part of the error proofing approach
to ensure that torque values or other parameter settings are NOT changed anywhere but at the Global
process monitor or in the Global Manager software. Details for this process are found in the Global
Manager software owner’s manual.

Sturtevant Richmont - P/N 857317 - Issue Date 161024 - Page 6 of 14
Setting Torque Values and the “Pull To Green” Threshold.
This is what is required to program a 1200 for use.
Using the Global Manager software, set the Unit of Measure (UOM), Minimum (Lo) Torque Specification,
Maximum (Hi) Torque Specification, Mode of Operation (Track, Residual or Peak), head length, auto-clear
time, direction of torque, batch size, and “green torque”. Directions are found in the Global 400 or 400mp
owners guide.
Calibration
Prior to calibration the radio on the wrench must be turned off.
There are two ways to release the tool from the Global 400.
Option 1: Using the Global 400/400mp: in the programming menu go to tools, select the tool
to be tested by pressing the ‘edit’ button. The page display changes and you need to press
the calibrate (cal check) button. This turns the radio off and allows you to check the tool and
if need be, calibrate it.
Option 2: If the Global 400 is unavailable, unscrew the 2 screws on the back of the 1200
Series Exacta 2, remove the plate, and physically disconnect the radio.
Once the radio is off, the tool must be connected to a computer using the serial port on the tool.
The calibration process for the Exacta® 2tools has three sub-processes. The fi rst is testing the tool to fi nd
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.
When calibrating and testing one of the tools having the SR dovetail that the calibration be performed with
the same Common Centerline Head Length (CCL) as the head length used in the original calibration. (see
page 2 of these instructions.) When changing the CCL the wrench has internal formula that compensates
for that change when that change is entered into the tool by the Global 400 or Global 400mp.
Batch size and green torque are features found only
in the 1200 Series.
Complete batch information is transmitted to the
1200. If radio connection is lost before a batch is
completed, the operator can continue to work and
complete the batch before the wrench disables
itself. Once radio communication is re-established,
the wrench automatically updates the process
monitor.
The green torque function allows you to set the
point at which the green light indicates to the
operator that target torque has been achieved.

Sturtevant Richmont - P/N 857317 - Issue Date 161024 - Page 7 of 14
We strongly recommend that the tool be temperature stabilized before testing, and that fully charged
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 Terminal software or a serial to USB conversion cable.
• The serial cable supplied with the torque wrench.
Setup for Adjustment
1. Ensure the computer is operating and is turned on.
2. Connect the serial cable or USB conversion to a port on the computer.
3. Connect the single-pin connector on the cable to the serial port on the tool.
4. Start the Terminal software.
5. Set the communication protocols within Terminal to the following settings:
Baud Rate = 19200 baud (tool default baud rate at startup)
Data bits = 8
Stop bit = 1
Parity =
None
Flow Control = none
Echo = On
6. Ensure that there is no torque load on the tool. Communication with the computer will be
established and the tool will send the fi rmware version and model information to the computer. In
Terminal, the information will appear approximately as it does in the next image.
1. Type the diagnostic “D” Command into the terminal and press <enter>. The Terminal program will
display “DiaOn”. You are now in diagnostic mode.
2. Type the M <enter>. The capacity of the tool should be seen on the display.

3. To enter the Calibration process, press the ‘Select‘ button on the tool keypad. You are taken to the
menu for units of measure.
4. Use the UP arrow to scroll through the units of measure to get to inch pounds (in lbs). Inch
pounds is the default calibration unit of measure for all Exacta 2 tools. When you reach inch
pounds press the Select key on the tool keypad.
5. The display will read “low” and then press select.
6. The display will advance to read “high” and then press select.
7. The display moves to the mode menu. Digital torque wrenches must be calibrated in track mode.
8. Press the UP arrow to move through the mode menu until it reads “otrac” which is track mode.
Press the Select key to choose track mode.
Calibration Procedure Overview
Note: Be sure to pull the wrench at least three (3) times in a clockwise direction prior to calibration.
This ensures the wrench is exercised and ready to be tested. Calibration points are established and
saved for each calibration point. Once clockwise calibration has been completed, be sure to pull the
wrench three times in the counterclockwise direction prior to calibration.
The calibration procedure starts at 0. Once that is established the process moves to 100% of tool
capacity and progresses down the scale. The clockwise (CW) direction is calibrated first and then the
counterclockwise direction is calibrated.
The DOWN arrow (v) saves each calibration point.
The UP arrow (^) advances the wrench to the next calibration point.
Calibration Procedure Keypad Functions
• Clear button – Restarts calibration process at Cal point CW 0.
• Down Arrow – Captures the calibration point value.
• UP Arrow moves the wrench to the next cal point.
• The first cal point is 0%.
• The up Arrow advances the tool to next cal point and always moves down the tool capacity scale from
the full tool capacity.
• Select button – Not used during this process. (If you hit the Select button in error during the calibration
process the program will exit the calibration process and the wrench will revert to operating mode. If
this happens the calibration process must start again from the beginning.)
Tool Display Note
• At this point the tool LCD display should be displaying “0” in the lower right corner.
• The tool display will use both the main display and the lower right-hand segment to show key informa-
tion needed during these processes.

Other Serial Communications Commands and Communications
The serial communications system used by these tools permits
fl exibility in terms of tool operation
control, data transfer and tool operation
Some of the functions covered in this section are only available through the use of Terminal or similar
terminal software.
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
Sturtevant Richmont 1200 Series Exacta 2 wrenches communicate at a baud rate of 19200. The Global
400 and 400mp baud rate is also 19200. Changing the baud rate on the wrench prevents that 1200 Series
Exacta 2 digital torque wrench from communication with the Global 400 or 400mp.

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.
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.
When using the tool with a process monitor, I got “rAd” and “BAD” on the display. What happened?
For one reason or another (power loss to process monitor, brownout, interference, etc.) the tool and
process monitor with which it is associated have lost radio communication with each other. The tool
attempted repeatedly to send the information with no success and is now notifying you of this.
You can (1) diagnose and correct the problem: it may be as simple as restoring power to the box, or
something more complex such as determining a new source of radio interference that has appeared. If the
radio interference cannot be removed, changing the channel on the Global 400/400mp will be necessary.
