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.
D) Since refrigeration systems are closed to the atmosphere, atmospheric pressure has no effect on refrigeration gauge pressure readings.
