The ZxD400xT has the following three types of display:
The values specified by the parameterisation are shown as a rolling display
in the operating display. The display is always in operating mode when the
display buttons are not operated. The meter returns automatically from the
display list to the operating display after a defined time. This display can
consist of one or more values.
By pressing the display button, the display check is activated, and from
there the user reaches the display menu by pressing the display button
again. From the display menu, values of the display list, the load profile(s),
the event log, etc. can be accessed. The values of the display list and also
the sequence can be parameterised. The display buttons permit scrolling
up and down in the list.
The user reaches the service menu by pressing the reset button starting
from the display check. From the service menu, values of the service list,
the set mode, etc. can be accessed. The service list, for example, is an
extended display list with additional values.
The values always displayed are considered the operating display. This can
be parameterised as a fixed display (only one value present, e.g. the
present tariff rate) or as a rolling display (several values alternate at a fixed
rate, e.g. every 15 seconds).

The meter can generate an error message on the basis of self-tests.
According to parameterisation, this can be permanently included in the
operating display. In the event of a serious error (fatal or critical error), it
replaces the normal operating display. After a fatal error, the meter no
longer operates and must be replaced. In case of a critical error, the error
message can be acknowledged with the display button.

In case of an error message, the procedure described in section 6.2 "Data
readout" should be followed.
