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.

enclosure's high-pressure port to the pressure tap on

of tubing from the control enclosure's low-pressure
port to the pressure tap on the clean-air plenum.
