Is it possible to zero it in house? Or needs specialist kit?
Thanks.
Indeed. Measurement of an amount of electricity usage will always depend upon subtracting some previous measurement, so I don't see why there would ever be a need, or point, in zeroing a meter.We recently had a new supply and a "new" meter supplied by the electric co. The meter was used and not zeroed. They just recorded the number and billed us from that value.
Indeed - just like car odometers. Mind you, with many things, if it's factory testing one is talking about, they quite often 'reset to zero' after the testing. It's subsequent (post-factory) testing (just like the 'delivery miles' of a car) that most often leads to the 'non-zero' readings when one first sees them.In fact meters often come with a small number showing which is caused by testing, so should be considered a good thing.
That sounds very credible.PV installers will usually write down a small positive amount as the initial reading (even when zero), because it seems the value zero often leads to extensive enquiries from the electricity company.
Actually they originally said it was 29,002 feet.I don't know whether there was ever any truth in the suggestion, but I was brought up to believe that when they initially 'measured' (well, more like 'estimated') the height of Everest they got an answer of exactly 29,000 feet - but that, since that looked 'too round' for anyone to regard it as credible as an accurate measurement, they added on a little, and told the world that it was 29,028 feet!
Oh - I've never seen that figure - it was certainly always said to be 29,028 during my formative years.Actually they originally said it was 29,002 feet.
Indeed. I must say that I thought it had risen a lot more than that in the past 70 or whatever years.It's continually rising because of the reason it is there in the first place, and, apart from one site which says 29,035, is reported now as being the 29,029 - which might be considered more unlikely than the original exactly 29,000.
