Locating measurement points
Using the main menu
Press ESC several times if
necessary to display the
general menu:
The current measurements in
the neutral are not displayed in
the case of a utility power without
distributed neutral.
Insignificant measurements
are replaced by * characters
on the terminal screen and
measurements where the capacity is
exceeded are displayed with #
characters on the terminal screen.
