# TRD - Torque Rate and Deviation

Tools
ES STR SL ST SR QST IXB

This step monitor measures and checks the torque rate, i.e. the ratio of torque vs. angle. The calculated torque rate is checked if it is within the torque rate limits defined by High Limit and Low Limit.

Parameter | Description
--- | ---
Trigger Torque | Torque of the angle start point.
Start Point Angle | When Start point angle has been measured from Trigger torque the measuring of the torque starts.
End Point Angle | Angle point where the measuring of the torque is stopped.
End Point Torque | Torque where the measuring of the torque is stopped.
Low Limit | Lowest acceptable torque.
High Limit | Highest acceptable torque.
Limit | Must be > 0
