f. Connect the DVM positive lead to TP1 (100x sensor voltage) and the

negative lead to TP4 (circuit common). The setpoint should still be set

at 100% flow (5.000 V). Measure the flow rate using a suitable

volumetric calibration equipment. To adjust the controller to the proper

full scale flow, calculate a new TP1 voltage using the following

equation:

Adjust the span potentiometer until the voltage at TP1 is equal to the

value calculated above. Recheck the flow rate after the flow has
