Pulse inputs and outputs
(optional)
By meters with pulse inputs, the pulse value can
be called up in the display (see the display over-
view, Level 4).
The pulse value of the outputs is permanently set
and corresponds with the last position of the as-
sociated display value.
Example:
Output 1 = energy output
Energy display = XXXXX.XXX
Last position = 0.001 MWh = 1 kWh
Output pulse = 1 KWh
