5.1.5 Calibrating the Flow Rate
Calibrate the flow rate if the Operational Qualification or Performance
Qualification flow rate accuracy and precision test fails.
Items needed:
• 0.076-mm (0.003-in) ID yellow PEEK tubing (P/N 049715) to create
14 ± 2 MPa (2000 ± 300 psi) of backpressure (if needed)
• High purity ASTM Type I (18 megohm-cm) filtered and deionized
water
• Balance capable of weighing more than 10 g with 0.001 g readability
• Tared beaker
To calibrate:
1. Open the ICS-900 Wellness panel (see Section 5.1).
2. Under Pump Flow Rate Calibration, click Calibration Procedure.
A panel with instructions and command buttons will open.
3. Follow the instructions on the panel to complete the conductivity cell
slope calibration procedure. The new slope is determined and stored
as the current value.
NOTE Enter the weight of the collected water (in
grams, to the nearest milligram).
4. Click Log to record the new calibration value in the Audit Trail. This
value is stored as the current value.
