from 20% to 100% of maximum range
+ /- 1 increment. The torque accuracy
is a typical value. Calibration point is on
the rubber grip. For keeping the accuracy,
calibrate the wrench for a constant period
time (1 year).

battery)
*3: Horizontal and vertical test.
*4: One cycle means swing the torque
wrench from 0 N-m to maximum range
and back to 0 N-m.
*5: Environmental test:
a. Dry heat
b. Cold
c. Damp heat
d. Change of temperature
e. Impact (shock)
f. Vibration
g. Drop
*6: Electromagnetic compatibility test:
a. Electrostatic discharge immunity (ESD)

BEFORE USING THE WRENCH
POWER ON AND RESETTING
THE WRENCH
Battery Installation
Attention
Cautions
■Remove the battery cap.
■Insert one AAA battery matching the -/+
polarities of the battery to the battery compartment.
■Replace the battery cap and fasten it tightly
according to the following figures.
If an external force is applied to the torque wrench
during power-on period, an initial torque offset
will be recorded in the memory.
During communication period (Send appears), the
auto power off function is disabled.
■Press to power on the digital torque wrench.
■Usually press to reset the digital torque
wrench before using it.
RESETTING THE WRENCH
AUTO POWER OFF
If the wrench does not function normally, loosen
the battery cap then tighten it to re-start.
The wrench will auto power off after about 5
minutes idle for power saving. Press to power
on the wrench again.

110% of torque of the spec.
2. When 90% of the target torque is reached, the
green LED will begin to flash and the alarm tone will
beep intermittently.
3. When 99.5% of the target torque has been reached,
the alarm will change to a steady tone and the green
LED will stop flashing and stay on. The red LED will also
illuminate.

MAINTENANCE AND STORAGE
BATTERY MAINTENANCE
■When the wrench is not going to be used for an
extended period of time, remove the battery.
■Keep a spare battery on hand when going on a
long trip or to cold areas.
■Sweat, oil and water can prevent a battery’s
terminal from making electrical contact.
To avoid this, wipe both terminals before loading a
battery.
■Dispose of batteries in a designated disposal
area. Do not throw batteries into a fire.
Caution:
1. Over-torquing (110% of Max. torque range)
could cause breakage or lose of accuracy.
2. Do not shake violently or drop wrench.
3. Do not use this wrench as a hammer.
4. Do not leave this wrench in any place
exposed to excessive heat, humidity, or
direct sunlight.
5. Do not use this apparatus in water (it is not
waterproof).
6. If the wrench gets wet, wipe it with a dry
towel as soon as possible. The salt in
seawater can be especially damaging.
7. Do not use organic solvents, such as
alcohol or paint thinner when cleaning
the wrench.
8. Keep this wrench away from magnets.
9. Do not expose this wrench to dust or sand
as this could cause serious damage.
10. Do not apply excessive force to the LCD
panel.
11. Apply torque slowly and grasp the center
of the handle. Do not apply load to the
end of the handle.
12. When checking the accuracy or calibration,
please use the bit head packed inside the
blow mold case.
Attention!
One-year periodic recalibration is necessary to maintain
accuracy. Please contact your local dealer for calibrations.
