Tips：Instructions for Magnehelic Differential Pressure Gauge Use

Measuring Positive Pressure: Connect the pressure source to one of the high-pressure ports using a tube, and seal the unused high-pressure port. Ensure one or both low-pressure vent ports are open to atmosphere.
Measuring Negative Pressure (Vacuum): Connect the vacuum source to one of the low-pressure ports, and seal the unused low-pressure port. Keep one or both high-pressure vent ports open.
Measuring Differential Pressure: Connect the higher pressure source to a high-pressure port and the lower pressure source to a low-pressure port. Seal any unused ports to ensure accurate differential measurement.

Refer to the installation diagrams for proper port connections and setup to achieve optimal performance.
