the display switches back to "r. outlet"
after approx. 4 minutes, if the choice
hasn't been activated as described
below. After another approx. 4 minutes,
the meter programs itself automatically
to "r. outlet", if the push button hasn't
been operated meanwhile.
The selection is being activated with the

The selected setting is accepted and
the unit is configured for the chosen
place of installation. The chosen place
of installation can be checked in the
first display of level 3 ("r. outlet" or "v.
inlet").
The meter is now ready for operation.
Pulse inputs and outputs (optional)
By meters with pulse inputs, the pulse
value can be called up in the display
(see the display overview, level 4). The
pulse value of the outputs is perma-
nently set and corresponds with the
last position of the associated display
value.

integrated current limiter.
Example:
Output 1 = energy output
Energy display = XXXXX.XXX
Last position = 0.001 MWh = 1 kWh
Output pulse = 1 kWh
