Tips and Hints

Use the PF5 flicker trend and half-cycle voltage or current trends to find the source of flicker. Press function key F1 to assign the arrow keys to selection of flicker, voltage, and current trends.

The 10 min (Pst) uses a longer measuring period to eliminate the influence of random voltage variations. It is also long enough to detect interference from a single source with a long working cycle such as electrical household appliances, and heat pumps.

A measuring period of 2 hours (Plt) is useful when there may be more than one interference source with irregular working cycles and for equipment such as welding machines, and rolling mills.
