How To Calibrate P/I converter.

How To Calibrate P/I converter./Procedure for P/I converter Calibration.

Equipments required:-

1. Supply voltage 24vdc,
2. Pressure source(handheld test pump),
3.  Multimeter.

Procedure for P/I converter Bench Calibration.:-

1. Set digital calibrator on measure mode.
2. Connect input signal i.e. 3-15 psig.
3. Set the input signal to 3 psi and check the output current as 4 mA.
4. If the current is showing more or less than 4 mA then adjust zero pot to make output 4ma.
5. Set the input pressure signal to 15 psi and check the output current 20 mA.
6. Turn the span adjustment potentiometer on Converter and adjust 100%.
7. Repeat step 3 to check that the desired low value (3 psi ~ 4mA) has not changed after adjusting the span.
