Timed start is settable. With the direction keys you can position the Cursor on a
particular Bar Graph. Measuring data belonging to the bar is shown in the screen
header.
Detailed measurement data is available under the Function keys:
F1
RMS voltage: events table, trends.
F2
Harmonics: bar graphs, events table, trends.
F3
Flicker: events table, trends.
F4
Dips/Interruption/Rapid Voltage Change/Swells: events table, trends.
F5
Unbalance, frequency: events table, trends.
The measuring data available under the Function keys is explained in the following
sections. Data is presented in the formats Events Table, Trend Display and Bar
Graph Screen.
Events table
The events table shows the events that occurred during the measurement with time
of start, phase and duration. Events recording situation:
V rms events: an event is recorded each time that a 10 minute aggregated
RMS value violates its limits.
Harmonics events: an event is recorded each time a 10 minute aggregated
harmonic or THD violates its limit.
Dips/Interruption/Rapid Voltage Change/Swells events: an event is recorded
each time one of the items violates its limit.
Unbalance and Frequency events: an event is recorded each time that a 10
minute aggregated RMS value violates its limit.
