Installation Guide - Position Transducers
How do I adjust the zero and span for the voltage conditioner, 4-20 mA, and bridge output signal conditioners?
First, unscrew the sealing screws labeled "Z" and "S" on the position transducer. Then, using a small, flat-
tipped screwdriver, rotate the appropriate trim potentiometer to adjust the zero and/or span. Clockwise rotation
increases the value and counter-clockwise rotation decreases the value.
