8.1.2.1 Closed Loop Dry Flow Calibration
The closed loop Dry Flow Calibration routine does not require the pump to run. Instead, the user must input 2
known flow meter flow rates versus current output points. The user will be prompted for these values. This process
can be used when it is not possible or not safe to run the pump during calibration.
Proceed with the following steps from the handheld remote:
1. Press the MENU key to access the Calibration Menu.
2. Press the ENTER key to access Pump Flow Calibration screen.
3. Press the ENTER key to access Dry Pump Flow Calibration screen.
4. Press ENTER to edit the high speed/flow mA reading and corresponding flow rate calibration point.
5. Using the UP/DOWN/ENTER keys enter the calibration mA and flow rate point.
6. After setting the high flow calibration point, press the ENTER key to accept the calibration point and proceed to
the low flow calibration point.
7. Press ENTER to edit the low speed/flow mA reading and corresponding flow rate calibration point.
8. Using the UP/DOWN/ENTER keys enter the calibration mA and flow points.
