Can changes in atmospheric pressure affect refrigeration gauge pressure readings?
A) Atmospheric pressure changes can affect high-pressure gauge readings, but not compound gauge readings.
B) Atmospheric pressure changes can affect compound gauge readings, but not high-pressure gauge readings.
C) Changes in atmospheric pressure can affect the final reading by changing the calibration point of the gauges.
