Prevailing torque controlled tightening
This phase allows you to check the residual torque (prevailing torque) that results, for instance from the thread formed with
tapping screws.
It is useful to know if the thread is formed correctly during
the desired number of rotations without untimely locking
or tapping deficiency.
The initial timeout allows you to start the readings when
the tool speed is stabilised. The memorised result is the
mean of the torque readings during the acquisition phase.
The system stops the acquisition of the torque and angle
when the motor stops. The torque pulse at the motor stop
is not taken into account.
