...Should have a needle valve built in it to depress the valve when you screw it on the fitting. I would charge with gas, not liquid, (with the engine running and the AC turned to cold)and when the frost starts getting close to the compressor on the line it should be good. If you overcharge it will cycle off because of the pressure sensor in the high side.
