Trend
During active recording TREND view is available (see section 3.14 for instructions how to start recording).
Flicker parameters can be observed by cycling function key F4 (METER -TREND). Note that Flicker meter
recording intervals are determinate by standard IEC 61000-4-15. Flicker meter therefore works
independently from chosen recording interval in GENERAL RECORDER.
