Current Monitoring

Current monitoring provides an extra security to monitor the tightening torque and is a complement to the torque sensor in the tool.

At final target torque, the rotor current is measured and converted to a torque value. If the calculated torque is within 10% of the measured torque, the tightening is considered to be OK.
