Voltage
The voltage should not be above or below 10% of the voltage marked on the tag at
the rear of the unit. To determine if the voltage is sufficient, the voltage should be
measured while the compressor is drawing its starting current. During this time, any
line drops will cause a significant voltage drop in inadequate wiring or on extension
cords. Open circuit measurements are not satisfactory.
