When to Calibrate: |
Every 6 months |
Turn off the pump flow.
Open the waste valve.
For GP40/50, IP20/25/25A pumps: The waste valve is on the pressure transducer. To open the valve, turn the knob about two turns counterclockwise.
For GS50/IS25 pumps: The waste valve is on the secondary pump head. To open the valve, turn the knob one-quarter to one-half turn counterclockwise.
Open the System Wellness Control Panel for the pump (see 
Opening a Wellness Control Panel).
Click the offset script button under pressure transducer. The pump calibrates the offset and uploads the new value to Chromeleon. Chromeleon stores this new offset as the current value.
Close the waste valve.
