This section explains how to perform IEC voltage fluctuation/flicker measurements.
Operating procedures are explained using the following setup methods.
• Procedure Using the Menu Icons (see page iii)
For the relationships between measurement operation (transition of the flicker measurement status)
and initializing, starting, and resetting, see the execution workflow of each measurement in the
Features Guide.
1.
Set the measurement mode to IEC Flicker according to steps 1 and 2 in section 14.1.
The Integration icon at the right edge of the screen changes to the Flicker icon.
2.
Tap the
Flicker
menu icon
. A Flicker menu appears in the sub menu area on the right side
of the screen.
3.
Set the voltage fluctuation/flicker measurement mode to Flicker or dmax.
A menu is displayed according to the selected measurement mode.
4.
Tap
Initialize Exec
to perform initialization.
Initialization takes about 30 seconds. When the flicker measurement status in the upper center of the
screen changes to “Ready,” the
Start
button is enabled.
5.
Tap
Start
to start measuring.
In dmax measurement mode, when the measurement of a single observation period is completed, the
measurement operation stops, and the flicker measurement status changes to “Ready.” To perform dmax
measurement 24 times, tap
Start
every time the status becomes “Ready.”
