The answer is B. When evacuating the system vacuum gauge, the vacuum gauge should be as close to the system being evacuated as possible. This will ensure that the reading of the gauge pressure is as accurate as possible before the evacuation of the system vacuum gauge from its currently location.

This is a very important step since having an incorrect reading of the gauge pressure can have negative effects if the gas pressure is too high. Make sure to double check this and other important steps when dealing with chlorofluorocarbon or any other type of gas.

The system vacuum gauge is one of the pressure measurements. A pressure measurement is an analysis used to calculate the force applied by a liquid or gas on a surface. Pressure is normally measured using units of the force in a surface area. The vacuum gauge is an instrument for measuring pressure.

The vacuum gauge is to be as close as possible to the system vacuum gauge being evacuated. This is for it to take the accurate reading of the gauge pressure before the system vacuum gauge is finally evacuated from its spot.
