Flickers
Flickers measure the human perception of the effect of amplitude modulation on the mains voltage
powering a light bulb. In Flickers menu instrument shows measured flicker parameters. Results can be
seen in a tabular (METER) or a graphical form (TREND) - which is active only while GENERAL RECORDER
is active. See section 3.14 for instructions how to start recording. In order to understand meanings of
particular parameter see section 5.1.9.
