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 GND terminal and the “+”(plus)
lead on the 0-5 pin terminal on (JP1) with the jumper removed. Be sure
to replace the jumper after checking.
OE258 Building Pressure Sensor Testing Instructions
Use the voltage column to check the Building Static Pressure Sensor
while connected to a powered expansion board. 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 Expan-
sion Board.
