Pulse inputs and outputs
(optional)
By meters with pulse outputs, the pulse value
can be called up in the display (see the display
overview, 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
