Flicker
Introduction
Flicker is available in Fluke 435-II and 437-II. It quantifies the luminance fluctuation of
lamps caused by supply voltage variations. The algorithm behind the measurement meets
EN61000-4-15 and is based on a perceptual model of the human eye / brain sensory
system. The Analyzer converts duration and magnitude of voltage variations into an
‘annoyance factor’ caused by the resulting flicker of a 60 W 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
120 V / 60 Hz or 230 V / 50 Hz. Flicker is characterized per phase by the parameters
shown in a Meter screen. The related Trend screen shows the changes in all measuring
values in the Meter screen.
Note: Flicker is not available for measurements in 400 Hz power systems such as offered
in Fluke 437-II.
