Note:
*1: The accuracy of the readout is guaranteed
from 20% to 100% of maximum range
+ /- 1 increment. Calibration point is at the
middle line of black circle area on the
rubber handle. For maintaining accuracy,
calibrate the wrench at regular intervals
(1 year recommended).
*2:
The angle accuracy is guaranteed at ±2°
when rotating wrench to 90° at speed of
30°/sec.
*3: Use a special designed cable (accessory) to
upload record data to PC.
*4: Two AA batteries
(Toshiba carbon-zinc battery)
*5: Horizontal and vertical test
*6: One cycle means turning the torque
wrench from 0 Nm to maximum torque
and back to 0 Nm.

cap Installation
BEFORE USING THE WRENCH
Battery Installation
■Remove the battery cap.
■Insert two AA batteries matching the -/+ polari-
ties of the battery to the battery compartment.
■Replace the battery cap and rotate it tightly
according to the following figures.

Reset the wrenchPower on and auto zero reset
■Set the wrench horizontally on a level surface and
let it sit without touching it, then gently press
to power on the digital torque-angle wrench.
■After power on, the LCD will flash first to do
auto zero-reset.
After doing auto zero-reset, a preset target will
show on LCD.
Attention:
If appeares during power-on process, it
means this wrench has been torqued to more than
110% of maximum torque.
Important!
When using the wrench in “ANGLE” mode the
wrench must be placed flat (horizontally) on table
or workbench before any attempt is made to
change values or to power up the unit. If the user
attempts these functions without following the
instructions above. The unit’s display will begin to
flash a series of four zeros in the top half of the
screen.In order to re-start the unit; press
■If necessary, Zero-reset will guarantee an
accurate measurement.
■After power on, button is for zero reset.
■Usually press to zero reset the digital
torque-angle wrench before using the wrench.
■In angle mode, keep the wrench steady without
any disturbance and press to do zero-reset.
■In torque mode, if an external force is applied
to the torque wrench during zero-reset period,
an initial torque offset error will occur.
If the battery serial voltage is in low, the wrench
will display a battery symbol and then turn off.
Replace batteries.
■The wrench will auto power off after about 2
minutes idle for power saving. Press to
power on the wrench again.
Cautions:
■During communication period (SEND appears),
the auto power-off function is disabled.
■If the wrench does not function normally or
appears, please go through the reset
process to reset the wrench.
■To reset the wrench, loosen the battery cap then
tighten it to re-start. After reset, remember to

2. Counting record: This feature counts how many
times the wrench has been used, but only counts
when applying up to 60% of max. torque. This re-
cord is not erasable until re-calibration. The feature
will count up to 65,000 measurements. Regarding
the number of measurements, the following figure
means the recorded count is 10100. (No-1 means
10000 times, No-2 means 20000 times reached
and so on…)
