6.2 LED indication (Energy pulsing)
The universal measuring device features two red LEDs on the front side to display active
and reactive energy measurements: kWh and kvarh. The LEDs flash each time a certain
energy value is reached (1 kWh or 1 kvarh).
The amount of energy displayed corresponds to the amount of energy measured by the
measuring device. In order to relate the flashing frequency to the amount of energy, the
transformation ratios and the pulse constant have to be considered.
