Calibrate Discharge Flow Sensor (Password Code 1111)
Note: Use a calibrated flow meter or Pitot gauge on the discharge under test as a reference.
When flowing water, ensure a constant pressure is maintained to obtain a steady flow rate.
For systems with multiple discharge flow sensors, calibrate each sensor separately.
Select a second reference flow rate and flow water for each discharge to verify the calibration. The flow rate
shown on the FLOW display should match the flow rate shown on the reference meter.
Once the system has been calibrated the System Restore function is used when a component is replaced.
