How to Calibrate the External Monitoring Device
When the CAL switch of the Unit indicator is pressed while “1” is indicated at the D-No. indication part of
the indicator in the real time mode, the CAL voltage is output at a potential difference of approximately
Δ3.75V from TORQUE OUT and, at the same time, the torque value recognized by the Unit is indicated
at the upper indication part. Adjust the torque voltage at the external monitoring device so that the
same torque value is displayed.
*The ZERO voltage in the no-load state is not 0V. The ZERO voltage value differs according to each
Unit and tool and correction at the external monitoring device is thus required.

● Angle Pulse, Normal/Reverse Output Part ● Current, Speed Output Part
The CAL voltage value is
indicated at the upper indication
part.
