8.1 Executing the Normal Voltage Fluctuation and Flicker Measurement
Selecting a Test Mode
• To perform a normal voltage fluctuation and flicker measurement (General mode),
select General.
• To measure dmax caused by manual switching (Manual dmax mode), select Manual.
• You can also select both General and Manual.
Initializing the Measurement
• The initialization takes approximately 30 s.
• Rms voltage Un and voltage frequency Freq are updated every 2 s while the
initialization is in progress in the same manner as when the voltage fluctuation and
flicker measurement is reset.
• Keep the voltage of the power supply to be measured in steady-state condition while
the initialization is in progress.
Rated Voltage Un and Voltage Frequency Freq
• If the assignment method of rated voltage is AUTO, the rms voltage at the start of
measurement is used as rated voltage Un. The measured data is calculated with
respect to rated voltage Un.
• If the assignment method of rated voltage is SET, the rated voltage setting is displayed
as Un(Set).
• Rated voltage Un and voltage frequency Freq are not updated after the flicker
measurement is started.
Resetting a Test
To initialize and restart the measurement, reset the measurement after the normal
voltage fluctuation and flicker measurement is complete and the flicker measurement
status is indicating Complete. You cannot initialize or start the measurement in the
Complete status.
In addition, reset the measurement to change the measurement conditions of the normal
voltage fluctuation and flicker measurement (section 3.3).
Flicker Measurement Status
The following five flicker measurement statuses are available.
