Minimum pulse duration (Addr. 010)
The minimum pulse duration can be pro-
grammed on 10 ms steps in a range between
50ms and 1000ms. The shortest pulse pause
corresponds to the programmed minimum pulse
duration.
At a minimum pulse duration of 50ms the maxi-
mum pulse frequency is 10Hz. If less pulses
must be transmitted, the pulse pause becomes
longer. The programmed minimum pulse dura-
tion of 50ms remains constantly.
Attention!
When the real energy meter with
reverse
running stop
works, pulses are only
given out while consumption of energy.
As the reactive energy meter works with
reverse running stop,
pulses are only
transmitted at inductive load.
Attention!
The pulse pause is not proportional to
power.

Pulse valence
The pulse valence tells you, how much energy
is related to one pulse (Wh or kvarh).
The pulse valence may not be confused with the
meter constant. The meter constant is given in
Meter constant = rotations per kWh
The correspondance between pulse valence
and meter constant can be seen in the following
relations:
Meter constant = 1 / pulse valence
Pulse valence = 1 / meter constant
