# Step Monitors

The availability of tightening steps, monitors and restrictions depends on the license installed on the controller.

The step monitors are used to verify that the tightening was achieved according to the specification, for example, angle limits or torque. Each step has mandatory step monitors and optional step monitors. The mandatory monitors are included when dragging a new step to the multistep program. The optional monitors are flexible and can be placed as needed in the multistep program. Every step can have up to eight monitors each.

The following monitors are automatically added to every step that is added to the multistep tightening program.
