Access to measurements and
parameters
The measurements and parameters can be accessed
using the metering, diagnosis, status and protection

They are arranged in a series of screens as shown in
the diagram opposite.
b The data are split up by category into 4 loops,
associated with the following 4 keys:
v key : measurements
v key : switchgear diagnosis
and additional measurements:
v key : general settings
v key : protection settings.
b When the user presses a key, the system moves on
to the next screen in the loop. When a screen includes
more than 4 lines, the user can move about in the
screen via the cursor keys ( , ).
