The waveform judgment trigger is specialized for the application of monitoring
commercial power supplies.
The comparison with the reference waveform begins from the point at which 0
V is crossed. Therefore, trigger judgment cannot be made correctly if, for exam-
ple, a waveform for which 0 V is not crossed or a noise waveform is input. Fur-
thermore, even if the frequency of the measurement target is a commercial
frequency (50/60 Hz), trigger judgment cannot be made correctly when a rect-
angular waveform is input or the signal level is not appropriate.
The set judgment area can be confirmed on the screen or on a printout.
