In order to find out an accurate reading on both the high and low sides you will do a superheat or subcooling calculation which includes the air off condenser temps along with liquid/suction line temp etc. That was knowledge that you needed to pass your EPA test so you should know the answer. If you do not have the required EPA certification then you should not be accessing the refrigerant system of your unit. I am just not into breaking the law here.
