6.7.1.1 Torque
This strategy guides the operator in reaching the desired target torque, without any angle reading.
Simply define the Cycle start, Minimum Torque, Target Torque and Maximum Torque, and the Change
Screw Torque.
The green area identifies the OK result area.
If the torque goes over the Change Screw value, a message is shown on the wrench display advising the
operator to replace the screw.
The torque result is the maximum torque measured during the tightening.
The STwrench LEDs, buzzer and vibration devices are activated as follows:
Torque result between Cycle Start and Min. Torque.
Torque result between Min. Torque and Max Torque.
Torque result over Max. Torque.
NOTE: The result LED indicating the result of the tightening is activated only when the tightening operation is
completed.
Cycle start
Min. Torque
Max. Torque
