4.3.- LED INDICATORS

The unit has two verication LEDs:

 To verify the active energy�

 To verify the reactive energy (according to version).

The weight of the LEDs is 20,000 imp/kWh (kvarh).

The LEDs will remain lit when the current is lower than the energy meter start-up current. Once

the start-up current is exceeded (due to active or reactive power consumption) the LEDs are

turned off and emit impulses that are proportional to the measured energy.
