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 keeping the accuracy,
calibrate the wrench for a constant period time (1
year).
*2: Horizontal and vertical test.
*3: Environmental test:
a. Dry heat
b. Cold
c. Damp heat
d. Change of temperature
e. Impact (shock)
f. Vibration
g. Drop
*4: Electromagnetic compatibility test:
a. Electrostatic discharge immunity (ESD)
b. Radiated susceptibility
c. Radiated emission
