5-18 Calibration and Adjustment
5.13 Calibrating the E/P Controllers
If the system is configured with the optional Electronic Pressure Control Utility, follow the procedure
below to calibrate the E/P Controllers. During the calibration process, you will ensure that the Fluidmove
pressure set point and Fluidmove pressure reading matches the external pressure gauge reading.

NOTE
This procedure assumes that the dispensing system is ON and Fluidmove is running.
Tools and Materials Needed:
• External Pressure Gauge
• Quick Disconnect Fitting
To calibrate the Fluidmove Set Point with the External Gauge Reading:
1. In the Fluidmove Main Window, select
Configuration > Setup Runtime Preferences >
Local Machine Offsets
.

The Local Machine Offsets window opens.
2. Select the Air Pressure tab (Figure 5-19).

This tab displays the Set Point, Set Point Offset, Reading Offset and Reading for
cooling, valve, and fluid pressure. The value in the “Reading” column is the same as the
value in the Current Pressure window (Figure 5-21) accessed by pressing [Ctrl + P] on
the dispensing system keyboard.

3. To establish air pressure set points, click on the numbers in blue, enter the desired values
and press enter. Click on
OK
.

It is best to calibrate valve air pressure with the same pressure setting that will be used
in the dispensing program. It is not necessary for cooling and fluid pressure adjustment.
