BEFORE USING THE WRENCH
BATTERY INSTALLATION
• Remove the battery cap.
Note:
*1: The accuracy of the readout is guaranteed from
*2: Use two AA batteries (Tested condition:
*3: Horizontal and vertical test.
*4: One cycle means turning the torque wrench
*5: Environmental test:
*6: Electromagnetic compatibility test:
• Insert two R6/AA batteries matching the -/+
• Replace the battery cover and rotate it tightly

ATTENTION:
20% to 100% of maximum range + /- 1
increment. The torque accuracy is a typical
value. Calibration point is at the middle line of
black circle area on the rubber grip. For
maintaining accuracy, calibrate the wrench at
regular intervals (1 year recommended). And
the accuracy is based on the zero degree of
offset from perpendicular drive.

to reset the digital torque
wrench before using it.
If an external force is applied to the torque
wrench during power-on/reset or wake up
period, an initial torque offset will exist in the
memory.
