Measurement screen

The initial screen shows the measured values of the real time line-to-neutral voltages. Use the arrow buttons to switch between the real time
line-to-neutral voltages and the 10-min average line-to-neutral voltages.

Menu structure

The following tables show the submenu structure and configuration possibilities as well as the pre-settings according to
CEI 0-21, which can be loaded in the submenu "General settings" -> "Load settings". Additionally, 5 sets of self-defined pre-settings can
be saved in the memory and loaded by the user.
