ZERO CALIBRATION:

1. With very little pressure on pump, Press Calibrate Min-Scale Twice. The Scale counts should be around 819.

2. Press SET twice to save calibration.

FULL-SCALE CALIBRATION:

1. Hold calibration switch up at pump truck. Pressure on remote box should be 15,000 PSI.2. Press Calibrate Full-Scale Twice. The Scale counts should be around 4095.3. Release calibration switch at pump truck.4. Press SET twice to save calibration.

Note* A pressure of -3750 psi means there is an open in circuit. Cable is un- plugged from transducer or bad cable. A shorted Circuit would cause a full scale reading like 15,000 psi or max temperature.
