I have a modern digital (LCD) electricity meter (installed around 2 yrs
ago, replacing the old spinning disc). It has a red light that flashes
so many times per kWh (as stated on the front) but sometimes when I
open the cupboard it shines red for a while (never time it and never
see it turn on anyway).
No significant current being drawn throughout the house, meter never
been fiddled with (before anyone asks!).
Once phoned the regional distribution company and they couldn't really
explain it.
Any ideas? Anything to worry about with regards to inaccuracy?
