CIRCUTOR CEM-C30 series - Manual (Page 15)

4.3.- LED INDICATORS
The unit has two verification 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 .
