Calibrating the Pump Flow Rate

Follow this procedure to calibrate the flow rate of the following pumps: GP40, GP50, GS50, IP20, IP25, IP25A, and IS25.

When to Calibrate:

Every 6 months

 

 

Items Needed:

Backpressure tubing to create 14 MPa ± 2 MPa (2000 psi ± 300 psi). Use 0.076 mm (0.003 in) ID yellow PEEK tubing (P/N 049715)

Deionized water

Tared beaker

 

  1. Verify that there is about 14 MPa (2000 psi) of backpressure.

  2. Pump deionized water at 1.0 ml/min.

  3. Allow the pump to stabilize for at least 5 minutes.

  4. Collect water into a tared beaker for exactly 5 minutes.

  5. Open the System Wellness Control Panel for the pump (see  Opening a Wellness Control Panel).

  6. Enter the weight of the water into the weight entry field under flow rate and press Enter. Chromeleon downloads the value to the pump and stores this calibration value as the current value.
