VOLTAGE
Make the following settings.
Items Settings
U wave
(Voltage waveform
comparison)
10%
The distortion component is detected by
comparison with the immediately preced-
ing waveform measurement, and is set as
a percentage (%) of range. The upper and
lower threshold levels are set.
U Transient
(Voltage Transient)
0.0600 kV
Specified as the noise level (in kV units)
superposed on the normal voltage wave-
form.
Upper and lower threshold levels are set.
To find the superposition area, you can
also detect extremely small amounts of
noise included where the normal voltage
waveform approaches the zero crossing.
