10 pressure ranges in same unit selectable via DIP-switches on pcb.
0 to 100 Pa, 0 to 250 Pa, 0 to 500 Pa, 0 to 750 Pa or 0 to 1000 Pa
-50 to +50 Pa , -125 to 125 Pa, -250 to +250 Pa, -375 to +375 Pa or -500 to +500 Pa
Other pressure units than Pa are available and selectable via DIP switches on pcb mmHH2O, mbar, inWG, mmHG, daPa, Kpa, hPa
Response time selectable via DIP switches on pcb - 0.5 ,1.0, 2.0 or 4.0 seconds
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 ( + - OUT ) on pcb terminals can be done by removing the grey rubber plug on the back side of the PAT device.
