OE271 Pressure Sensor Testing Instructions
Use the voltage column 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 0-5 pin terminal on (TP) with the jumper removed. Be sure
to replace the jumper after checking.
