Duct Static Pressure Sensor
Testing Instructions
Use the voltage column, Table 21, this page, to check the Duct
Static Pressure Sensor while connected to powered controllers. Read
voltage with meter set on DC volts. Place the “-” (minus) lead on
the GND terminal and the “+” (plus) lead on the right side of the
resistor labeled R85. Be sure to replace the jumper after checking.

Building Pressure Sensor
Testing Instructions
Use the voltage column, Table 22, this page, to check the
Building Static Pressure Sensor while connected to a powered
expansion module. Read voltage with meter set on DC volts.
Place the “-” (minus) lead on terminal labeled GND and the “+”
lead on terminal AI5 on the VCCX-IP Controller.
