*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 on the rubber grip. For keeping the accuracy, calibrate the screwdriver for a
constant period time (1 year).
*2: Use a special designed cable (accessory) to upload record data to PC.
*3: Use one AAA batteries (Test condition: Toshiba carbon-zinc battery).
*4: Horizontal and vertical test.
*5: One cycle means twist the screwdriver from 0 cN-m to maximum range and back to 0 cN-m.
*6: Environmental test:
a. Dry heat
b. Cold
c. Damp heat
d. Change of temperature
e. Impact (shock)
f. Vibration
g. Drop
*7: Electromagnetic compatibility test:
a. Electrostatic discharge immunity (ESD)
b. Radiated susceptibility
c. Radiated emission
