Pulses / s submenu
Every pulse that is outputted via the two pulse outputs corresponds to an amount of energy in Wh.
This “pulse weight” can be set in the Pulses/s menu.
This is necessary, as the pulse output can
supply a maximum pulse frequency of 10 Hz;
this corresponds to 36000 pulses/h.
The maximum admissible pulse weighting factor can be calculated with the following equation:
P = max. connected load in Watt
X = pulse weighting factor in Wh/pulse
Example: If the consumer to be measured is a machine with P
ges
= 100 KW
In practice, electric meters often have a pulse constant (here K) in pulses/kWh. To convert X into this
constant K:
In our example, this means:
Practice has shown that a pulse rate of 100 pulses/kWh (= 10 Wh/pulse) is entirely sufficient.
