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.
