3.6 Flicker
Flicker quantifies the luminance fluctuation of lamps caused by supply voltage
variations. The Analyzer design strictly meets the
IEC61000-4-15
Flicker Meter model.
The Analyzer converts duration and magnitude of voltage variations into an
‘annoyance factor’ caused by the resulting flicker of a 60W lamp. A high flicker reading
means that most people would find the luminance changes irritating. The voltage
variation can be relatively small. The measurement is optimized to lamps powered by
120V/60Hz
or
230V/50Hz
. The Trend screen shows changes of instantaneous flicker
sensation level over time.
Note: Flicker function is not applied to 400Hz power system measurement.
