Viewing recorded measurement data
Monitoring fluctuation in MAX, MIN, and AVE values for har-
monic RMS voltage over a 1-week period
(1) Checking whether total voltage distortion specified in the IEC
Standards has been exceeded.

MAX value: Yellow
AVE value: Green
MIN value: Red
An event occurs when the total voltage distortion factor or harmonic
current limit specified in the IEC Standards is exceeded.
If the mark is displayed in the time series graph, an event has
occurred. However, an event occurs whenever recording starts and
stops.
