Configure Flow Meter Settings

The accuracy of the PCF volume reporting depends on
precise adjustment of the K-factor(s). The fluid plate
uses the K-factor(s) to calculate the volume dispensed.
If the set value is not correct, the system still delivers
repeatable flow rates; however, the reported value may
not be correct. See Verify Flow Meter Calibration,
page 46, for additional K-factor information.

The PCF system uses variables (Kp, Ki, and Kd) in the
software calculations to accurately and precisely control
the fluid pressure.
NOTE: It is recommended that these values are not
changed from the factory defaults of 32.00 for Kp,
128.00 for Ki, and 0.00 for Kd. However, if the values
need to be adjusted, see Manually Adjust Control
Loop Parameters on page 47.
