7. Measuring AC Voltages
The output wave of the AC inverter is a MODIFIED SINEWAVE. An AUTHENTIC RMS VOLT METER is required to
measure the AC output voltage. Using any other type of voltage measuring device will result in an AC voltage
reading that is up to 20 to 30V lower than the rated value. Only an authentic RMS voltmeter provides an accurate
reading.
