[PDF] The Semi Hermetic Compressor Book the compressor contactor load side while the compressor is operating. The most accurate way to measure what is occurring at the compressor is to read the voltage at the compressor terminals. For example, if: L1 to L2 is 220V, L2 to L3 = 231 V., and L3 to L1 = 235 V. the average is 220 + 231 + 235 divided by 3 or 229V.
