Mounting and Electrical Measurement


To mount the PAT air differential pressure transmitter,
mount the ABS plate on the wall.

Insert the PAT air differential pressure transmitter on the fixing plate.

Rotate the housing in clockwise direction until you hear a 'click' which
confirms that the PAT air differential pressure transmitter is correctly installed.

Electrical Measurement

Electrical measurement ( + - OUT ) on pcb terminals can be done by removing the grey rubber plug on the back side of the PAT device.
