8. Auto power off
When it is left without any key operation of tightening operation for a set time
(default setting is 3 min.) or unloading condition (loading torque is 7.5 % less than
the max. torque range of the model), the power will automatically turn off.
If you prefer not to use auto power off, set it to OFF. At”LoBATT” alarm condition,
power will turn off in 1 minute regardless of the above condition.
9. Residual battery indicator
Residual battery amount is indicated on the display as follows:
9. Over-torque alarm
When it exceeds 105% of the maximum measurable torque, the value on the display
and ”－－－－” blinks alternatively and the buzzer goes off.
10. Over-torque alarm/Peak torque hold starting value for each CTA2-G models.
