Trim Current Calibration
Zero Trim—Zero trim is an adjustment to the current calibration. This adjustment assumes that the current torque rate
is correct and the PV error is due to a shift in the zero position.
Gain Trim—Gain trim is an adjustment to the current calibration. This adjustment assumes that the zero point is correct
and the PV error is caused by a torque rate change.
Default Gain—Default Gain is an adjustment to the current calibration. This adjustment requires you to set the default
gain to the known torque tube rate.
