Notes:
1. 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.
