By closing the valves on both the low and high side of the gauge, a pressure will be exerted on them and the maintenance personnel will be able to determine the refrigerant that is currently existing on the aircon system.

In addition to reading the pressure, the temperature can also be determine on both the suction and discharge pipe from the gauge.
