checking charge

I've studied some of the online info about checking charge via the temperatures and pressures and charts, superheat, etc. When checking the temperature with the digital thermometer, do you take the reading just outside the outdoor unit or near the evaporator for the high and low side. Also, what is a good way to attach the probe to the lines to assure an accurate reading.
