Measurement of voltages and currents
Since the voltages and currents on the inverter power supply and output sides include
harmonics, accurate measurement depends on the instruments used and circuits
measured.
When instruments for commercial frequency are used for measurement, measure the
following circuits using the instruments given on the next page.
