Calibration:
All standard HMPT pressure transducers are equipped with an internal shunt calibration feature which,
when activated, will produce an electrically stimulated output of 80% full scale.

Allow the transducer to reach operating temperature. With no pressure applied, adjust the zero balance
potentiometer located under the steel screw on the amplifier housing.

Next, engage the Calibration Push Button [C]. Adjust the SPAN potentiometer located under the seal
screw on the amplifier housing until the output is equal to 80% of the full scale output.

Recheck the zero output.
