Overview

The overview submenu gives a complete list of all measurements.
System Values
Network measurements like voltage, current, Power, Energy and Temperature etc. For Three Phase Model RVT12-3P,
system values for each phase are available as well, for instance, the power factor for Phase 1, 2 and 3.
Waveform
System voltage and current (phase to phase or phase to neutral) can be displayed in Sine wave waveform.
Event Logging
This submenu allows the user to view the extreme values of some key parameters.
Meter
This function offers a possibility for the user to display three most concerned measurements in one screen. For in-
stance, three line voltages can be shown in one screen in a better resolution and better view. Detailed instructions for
this function can be found in 4.2.4.
