Calibration

Pressure

The pressure should be calibrated at least yearly or whenever the pressure

transducer has been replaced.

1. Connect a calibrated pressure gauge to the thermocouple port in the cell

cap.

2. Start the calibration procedure:

a. For onboard control, touch Calibrate and then Pressure.

b. For software control, select Pressure Transducer from the Calibrate

menu.

3. Follow the instructions on the screen.
