5.3.5. ScreenSaver
To increase the longevity of the touchscreen, the touchscreen will automatically dim after 90 minutes.
Select this button to toggle on and off the ScreenSaver.
5.3.6. AutoZero Settings
AutoZero, if included at the Factory at time of order, will run automatically as set on this screen or can
be run manually upon pressing the “Run AutoZero” button on this page as shown below. The AutoZero
function will engage a solenoid valve to common mode the transducer creating a zero-pressure
differential. During this time the flow, velocity, or pressure values being read by the device and the
resulting System outputs will be held at their current state prior to the AutoZero function. The AutoZero
calibration will be stored to a different memory location than that of the Factory Zero Calibration. The
AutoZero function is optional and typically applies to OA applications where very low differential
pressure could have high square root gain in flow calculations.
AutoZero Enable/Disabled
If the user wishes to disable the AutoZero function for whatever reason, the following enable/disable
selector switch has been made available.
AutoZero Interval
The AutoZero interval settings adjusts the frequency at which the AutoZero runs. The range is 1 to 24
hours at 1-hour increments. (Values greater than 24 can be entered however the units are then in
seconds, not hours. This is for troubleshooting purposes and PCI does not recommend running the
autozero valve at that frequency.)
Default is 8 hours.
