degree. Press or to get to the required angle, then press
7. The wrench is ready to use.
8. Apply torque and rotate the wrench at a constant moderate speed until
alerted to stop by the handle vibration, beeps and LCD display.
9. To take the next measurement press or wait until the display stops
flashing.
Note: After reaching the target angle the display will flash for 10 seconds, then
default to the last setting.
For better accuracy the torque wrench should be rotated between
10 degree/sec – 180 degrees/sec.
7. How to Change “Target Torque
Alert” and “Target Angle Alert”
Percentages
1. Power on the wrench as
described in Section 1.
2. Press until the “PCt” mode is reached, then press . .
3. The current value will flash on the screen.
4. Press or to select when the target torque alert will start. The
target torque alert can start at a maximum of 50% to the target torque value
or a minimum of 1% to the target torque value. For example, if your target
torque is 100 ft-lbs and your target torque alert is set at 50%, the alert will
start when you reach 50 ft-lbs. Press to save.
5. The screen will show “dEG” so the target angle alert can be adjusted.
6. Press to change the target angle alert setting. Press or
to select when the target angle alert will start. The target angle alert can
start at a maximum of 50 degrees before the target angle or a minimum of 5
degrees before the target angle. Press to save.
7. The wrench is ready to use.

of the screen and the torque value will be flashing.
3. Press or to select the desired pre-set torque value, then press
for 3 seconds, after which the wrench will beep.
4. Now the pre-set number at the top of the screen will flash. Press or
to select the desired torque setting, then press . The new Pre-Set Value is
saved into the Pre-Set options.
5. Press again to set the target torque as to the new Pre-set value.
10. How to Set Torque with Angle
1. Power on the wrench as
described in Section 1.
2. Place the torque wrench on a
stable flat surface to calibrate.
3. Press until the “PA” mode is reached, then press .
4. The screen will show “OOOO” as
the wrench calibrates, then will
show last angle and torque value set.
5. If the desired angle and torque
values are displayed, the wrench is ready to use.
6. If you want a different torque

next measurement press or wait until the display stops flashing.
11. Low Battery
1. When the remaining battery capacity is at 30%, the battery icon on the dis-
play will flash. The Electronic Torque Wrench will still function, but the battery
will need to be replaced soon.
2. When the remaining battery
capacity is at 10%, the battery icon
will show continuously. The Electronic
Torque Wrench will not function correctly. Immediately replace the battery.
12. Changing Batteries
1. Use AA (Alkaline) Batteries only.
2. Remove Batteries if the torque wrench is not used for an extended period
of time.
3. Unscrew end cap 4. Insert 2 AA (Alkaline) Batteries 5. Replace End Cap
13. Maximum Capacity Exceeded
1. When the applied torque exceeds
the wrench full-scale capacity the
LCD screen will show red. The
display will show “ovEr”.
2. Verify the calibration of the wrench if you know its capacity has been
exceeded.
How to Apply Torque
1. This Electronic Torque Wrench is designed so that when force is properly
applied to the handgrip, a continuous audible signal, the LCD screen display
and vibration in the handle will indicate that the Target Torque or Angle has
been attained. DO NOT pull beyond this point.
Caution: The audible signal, LCD screen display and vibration in the the handle
are indicators that the proper torque or angle have been attained. Over torqu-
ing beyond these signals could cause fastener failure.
2. To properly apply torque, attach socket securely on torque wrench square
drive and position socket on fastener so that tilting will not occur. Grasp the
center of hand grip and apply a slow steady increasing force perpendicular
(90 degrees) to the torque wrench body and perpendicular (90 degrees) to the
center line of the square drive, socket and fastener.
3. Turn the fastener down with a smooth and even force applied to the handle
of the torque wrench. As turning resistance increases, pull more slowly. To
assure accuracy, the fastener must be in motion when the torque measure-
ment is made.
WARNING: Any change from the above procedure will result in a change of
torque being applied. This includes standard torque wrenches, flex-head
torque wrenches, universal joints, and universal sockets. DO NOT USE universal
joints or universal sockets due to the complexity of determining the associated
error. If you need angular access, use a flex-head torque wrench.
Extensions
When it is necessary to use an extension that changes the effective lever
length of the torque wrench, torque being applied will change.
Compute adjustments as follows:
TW - Torque set on Wrench
TE - Torque applied by the extension to the fastener
TW = (TE x L) / (L + E)
TE = (TW x (L + E)) / L
Notice: Socket extension bars that are axially in line with the square drive do
not cause error and need no adjustment.
Apply torque and rotate the wrench at a constant moderate speed until alerted
to stop by the continuous audible signal, the LCD Screen display and handle
vibration.
Certification
This torque wrench was calibrated prior to shipment from the factory within
tolerance limits of:
• Torque (unflexed): +/- 2% CW, +/- 3% CCW from 20% to 100% of capacity
• Angle: (+/- 1% of reading) + (+/- 1 degree @ angular velocity >10 degree/
sec <180 degree/sec) + (+/- 1 degree of test fixture)
