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.
14. Tracking Mode
1. Power on the wrench as described in
Section 1.
2. Press to scroll through the different modes
3. Select “
trAc
” to enter Tracking Mode. There will be a T sign next to the
battery indication.
4. In this mode, there will be not target torque or angle value. The display will
show the real time torque and value applied to the wrench.
5. You may press to reset the angle value to 0
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 handle
are indicators that the proper torque or angle have been attained.
Over torquing 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)
Limited Warranty

or workmanship free of charge. Improper use of these products, including but
not limited to the application of excessive force, will affect performance and
may result in injury. The warranty does not apply to wrenches which do not

• Never use the torque wrench with the power off. Always turn on the
torque wrench so the applied torque is measured.
• Do not press any key while torque is being applied.
• Do not use electronic torque wrench to loosen fasteners.
• Verify the calibration of the wrench if you know or suspect its
capacity has been exceeded.
• Periodic recalibration is required to maintain accuracy.
• Never apply more torque than the maximum wrench capacity or the
maximum fastener specifications.
• Do not immerse in fluids.
• Do not use on live electrical circuits.
• Electrical shock can cause injury. Rubber handle is NOT insulated.
