It connects for the side where the compressor discharges and measures the high pressure there. Its scale runs from zero to 500 psi (pounds per square inch).2Observe the reading on the blue gauge diagnostic car tool. It connects to the low pressure side on the compressor and measures the low pressure or suction present there. It has two scales on the identical circle. Clockwise from the zero reading, it measures pressure between zero and 350 psi. Counterclockwise from zero, it measures vacuum amongst zero and 30 Hg (inches of mercury).3Note last that even though the pressure readings are on the inner scales of both gauges, you can find temperature readings on outer scales that also tell you the refrigerant temperature at both sides.
