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.
OE258-01 Building Pressure Sensor Testing
Instructions
Use the voltage column 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 AIN4 on the Analog Input/Output
Expansion Module.
