Unload Bottle Remove bottles from the bottle bay.
7. Push START.
If Calibrate Pump was selected, the analyzer pumps water for 30 seconds.
8. For pump calibration, enter the volume pumped as measured in the graduated cylinder.
The test results give the:
• Test Time— Always 30 seconds
• Expected Results—The calculated amount of water that should be measured during the test.
The formula is: V = Flow rate ÷ Test time, where Flow Rate = The target flow rate of the pump
as entered in the Actual Results text box.
• Actual Results—The actual amount of water measured during the test.
9. Push the previous icon to save the calibration results.
