The Flow Sensors script calibrates the flow sensors for pumps A and B.
Use this script to do the following:
• Periodically check the accuracy of the flow sensor calibration for your maintenance
records (select the Inspection Only check box).
Note If the last flow sensor calibration dates back more than 6 months, a reminder will be
shown on the home screen.
• Calibrate the flow sensors when you change the solvent composition of either solvent A or
B (clear the Inspection Only check box).
This calibration does not require any additional plumbing.
IMPORTANT Because the flow sensor calibration requires a stable operating temperature,
ensure that the instrument's side panels are installed and that the instrument has been on
for a minimum of 30 minutes.
