How to use digital HVAC gauge?

A digital HVAC gauge is a tool used in heating, ventilation, and air conditioning (HVAC) systems to measure the pressure and temperature of refrigerants and other HVAC fluids. Here is a general guide on how to use a digital HVAC gauge:

  1. Choose the right port: Digital HVAC gauges have either a low-side or high-side port for measuring refrigerant pressure. Be sure to choose the correct port for your measurement.

  2. Connect the gauge: Attach the gauge to the port on your HVAC system. Make sure the connection is secure and there are no leaks.

  3. Turn on the gauge: Most digital HVAC gauges have a power button or switch. Turn it on and wait for the gauge to stabilize.

  4. Take the measurement: The digital display will show the current pressure and temperature of the refrigerant or fluid in the system. Read the values and record them if necessary.

  5. Turn off the gauge: Once you have taken the measurement, turn off the gauge and disconnect it from the HVAC system.
