1. Calibrates the 0 µL/min point. Then inspects and evaluates this first
calibration point.
2. Calibrates the 500 µL/min point. Then inspects and evaluates this second
calibration point.
When you select the Inspection Only check box, the script does not apply the new
calibration. Selecting the Fast Inspection option instead of the Exact Inspection
option reduces the duration of the inspection and evaluation steps from 16 minutes
to 5 minutes, without reducing the accuracy of the calibration.
c. Do one of the following:
• Type in the acetonitrile concentration for solvent B.Type in the acetonitrile
concentration for solvent B.
Note Acetonitrile concentrations higher than 95% shorten the lifetime of
system components. An acetonitrile concentration of 80% in water is
recommended for solvent B.
• To check the accuracy of the current calibration (only inspect the current
calibration), select the Inspection Only check box.
Note When you select the Inspection Only check box, the program does not
recalibrate the flow sensors.
• To calibrate and inspect the flow sensors (and apply the new calibration), clear
the Inspection Only check box.
d. Select the inspection duration as follows:
• When you want an estimate of the flow sensor accuracy, select the Inspection
Only check box and the Fast Inspection option.
• When you are recalibrating the flow sensors, clear the
and select the Exact Inspection option.
3. Press Start.
This script auto-zeroes the pressure sensor.
