3.6 Flickermeter
Flickermeter measures the human perception of the effect of amplitude modulation on
the mains voltage powering a light bulb. In Flickermeter menu instrument show
measured power parameters. Results can be seen in a tabular (METER) or a graphical
form (TREND). TREND view is active only while RECORDER is active, too. See section
3.10 for instructions how to start recording. In order to understand meanings of
particular parameter see section 5.1.9.

By entering FLIKERMETER menu from MAIN MENU the FLIKERMETER tabular screen
is shown
