5.2 Negative Pressure Measurement
Connect the pressure tubing to either of the two ports marked “low pressure” on the gage and
plug the other one. Vent the ports marked “high pressure” to atmosphere.
5.3 Differential Pressure Measurement
Connect the higher pressure tubing to either of the two ports marked “high pressure” on the
gage and plug the other one. Connect the lower pressure tubing to either of the two ports marked “low
pressure” on the gage and plugging the other one.
6. INSTALLATION
6.1 Recommendation
 Upon receipt please inspect the instrument for the intended application range.
 The instrument should be installed in a place where excessive pressure is not present and the
ambient temperature is less than 140°F (60°C).
 All standard MG gauges are calibrated in the vertical position. To maintain the specified
accuracy, the gauge must be mounted in the vertical position.
6.2 Surface Mounting
Drill 3 holes spaced equally apart on a 4 1/16" diameter circle to match the holes on the back of
the gauge. Secure the gauge with 3 mounting screws of suitable length provided.
