◦
The reverse rotation of the screwdriver is not evaluated.
◦
The allowable error range at the time of purchase is set to 10% for both upper and lower limits. If you

If no error is detected in the screw tightening work, one of L.G, GOOD or H.G indicator is lit and the buzzer
sounds.

If the torque is within the learning values, the GOOD indicator will be lit, and if it falls within the allowable
error range, either L.G or H.G indicator will be lit. Conversely, when the torque is less than the lower limit
value, the L.NG indicator will be lit, and when the torque exceeds the upper limit value, the H.NG indicator
will be lit, which means fail.
