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 instance, 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
