Operating temperature: -10º c ~ 60º c.
Storage temperature: -20º c ~ 70º c.
Humidity: Up to 90% noncondensing.
Drop test: 1 m.
Vibration test *3: 10 G.
Life time *4: 10000 cycle.
Environmental test *5: Pass.
Electromagnetic compatibility test *6: Pass.
Note:
*1: The accuracy of the readout is guaranteed from
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.
*2: Use two AA batteries (Tested condition:
Toshiba carbon-zinc R6UG battery).
*3: Horizontal and vertical test.
*4: One cycle means turning 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)
b. Radiation susceptibility
c. Radiation emission
BEFORE USING THE WRENCH
BATTERY INSTALLATION
• Remove
the battery cap.
• Insert two R6/AA batteries matching the -/+
polarities of the battery to the battery
compartment.
• Replace the battery cover and rotate it tightly
according to the following figures.
• Press to power on the digital torque wrench.
• Usually press to reset the digital torque
wrench before using it.
ATTENTION:
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.
