Result var.: "TR" (step torque rate) and "TR Dev" (step torque rate deviation).
Alarms: Torque rate too low (TRL), Torque rate too high (TRH) and Too big deviation (DEV)
Trace: The calculated torque rate line and the Dev lines are shown as in the diagram above. The
lines are only shown when Torque vs. Angle is selected and Check limits are enabled in the
trace form (see View of trace curves).
