Measure the commercial power supply
Measure the commercial power supply
The following explains the method of recording a voltage waveform for
the commercial power supply of 200 V AC (50 Hz /60 Hz), including the
method of saving the data after measurement. For one instance, the level
trigger is used to measure waveforms.
To measure repetitive waveforms such as the commercial power supply,
setting the standard level trigger level as the measurement start point will
make it easier to observe the waveforms.
