Ensuring System Wellness (IC Devices)
Calibrating the ICS-90 Pressure Transducer

When to Calibrate:

  • After installing a new transducer

  • Every 6 months

 

About 10 minutes before starting the calibration, toggle the injection valve position a few times by clicking the valve Load and Inject buttons on the ICS-90 Control Panel. This removes any air or contaminant buildup in the injection valve loop.

  1. Turn off the pump flow.

  2. Open the waste valve on the front of the pump head by turning the knob counterclockwise two turns.

  3. Open the ICS-90 (or ICS-90A) System Wellness Control Panel (see  Opening a Wellness Control Panel).

    If you are unsure whether your system is an ICS-90 or ICS-90A, check the model data label on the rear panel.

  4. Click the Calibrate Offset script button under pressure transducer. The pump calibrates the transducer and uploads the new value to Chromeleon. The new offset is stored as the current value.

  5. Close the waste valve.

  6. Connect a pressure gauge between the pump outlet and the pressure transducer. Turn on the pump and let the system stabilize. Note the average pressure reading on the gauge, and enter this reading in the measured field.

  7. Click the Calibrate Slope script button under pressure transducer. The pump calibrates the slope and uploads the new value to Chromeleon. The new slope is stored as the current value.

  8. Turn off the pump.

  9. Disconnect the pressure gauge. Reconnect the pressure transducer to the pump.
