INSTALLATION
Mounting
A vertical position required. That is the position in which all standard models are
calibrated at the factory. Provide a 4-9/16˝ diameter opening in panel. Insert gage
and secure in place with provided screws and adapters.
Included Accessories:
Mounting lugs – 3
6-20 x 2-1/2 screws – 3
4-20 x 3/8 screws – 3 (mounting hole depth is 3/8˝ [9.53])
Cable gland – 1
Pressure Connections
Two integral tubing connections are provided on the back of the gage. They are
sized to fit 3/16˝ (4.8 mm) I.D. x 5/16˝ (7.9 mm) O.D. flexible PVC tubing. To
measure single positive pressure, connect tubing to the + port and vent the – port
to atmosphere. To measure single negative pressure (vacuum), connect tubing to
the – port and vent the + port to atmosphere. To measure differential pressure,
connect higher pressure to the + port and lower pressure to the – port. Be sure the
pressure rating of the tubing exceeds that of the operating ranges.
Electrical Connections
A 9V battery or an external power supply 9-24 VDC can be used to power the unit.
If both battery and external power supply are connected, the battery will work as
back up power.

The unit is shipped with a separate 9V alkaline battery. Remove the unit’s top back
cover, do not remove bottom cover. Connect the 9V battery to the battery holder as
shown in Figure 1. Replace top back cover and tighten screws to 2 ±.25 in. lbs.
