output. If the value is 357 or lower, the actuator will not allow you
to calibrate the zero output. The value must be larger than 357

2001/2002 Actuator comes already calibrated from the factory. If it becomes necessary to
do a calibrationin the field, adjust the output using the procedure in Table 28. Refer to Figure 26 for a
diagram to connect a signal source to the actuator input and a DVM to measure actuator output signal.

ATTENTION
For a slidewire emulation output calibration to be saved, you must complete the procedure.
The calibration will not be saved if you exit without completing the steps of the procedure.
