Delta P Plus Control Calibration
The only user calibration is the zero adjustment of the
display. Due to slight changes in electronic components
over time or pressure within the plant environment, the
display may read something other than 0.0 while at rest.
Use the following procedure to recalibrate the operating
system.
1. Turn power to the Delta P Plus Control ON for a
minimum of 30-minutes to stabilize the operating
temperature.
2. Disconnect the pressure tubing, either leaving it to
atmosphere, or connecting the two barbed fittings
together with a short length of tubing.
3. Use the Menu key to select PAS.
4. Press SET, then use the arrow keys to display “4”,
press SET again.
5. Press the MENU key repeatedly until you reach P 14.
6. Press SET, then use the arrow keys to display “1”,
press SET again.
7. After 10 seconds with no further button action, the
display will return to reading the pressure.
8. Connect one section of tubing from the control
enclosure’s high-pressure port to the pressure tap on
the dirty-air plenum. Connect the remaining section
of tubing from the control enclosure’s low-pressure
port to the pressure tap on the clean-air plenum.
