Fine-tuning the Two step strategy
When the First target is reached the tool will make an immediate stop for a
specified time before it continues with the final step. The First torque value and
the Pause time should be chosen to improve ergonomics for hand-held tools.
Three step
The Three step strategy adds a loosening step between the first step and the fi-
nal step to overcome short-term relaxation effects due to embedment, and re-
duce preload scatter. This is sometimes called to condition the joint. This can be
useful in, for example, joints with many adjoining surfaces and will have
greater effect on new parts than on reused ones due to the smoothening of sur-
faces which will reduce embedment.
Conditioning the joint is done by tightening the first step to a given torque,
First torque, and then releasing the load by turning the nut a specified Condi-
tioning angle and then retighten the nut to its Target torque.
