Bought a Landis E110 digital meter, thought it was zeroed, but not so, when it came.
Is it possible to zero it in house? Or needs specialist kit?
Thanks.

No - not possible for mere mortals.
And with the proper kit, no-one is going to give you the password.
 
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. 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.

There's not even an 'aesthetic' reason, since, after the initial very brief period after it's first installed, even a 'zeroed' meter will not show zero again for a very very long time (and then only transiently).

In fact meters often come with a small number showing which is caused by testing, so should be considered a good thing. 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.
 
That's because most people don't class zero as a valid number, however, in accounting zero is used as a number and comes in very useful when working out formulas/equations to a set number of decimal places.

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.

That sounds very credible.

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!

Actually they originally said it was 29,002 feet.

Oh - I've never seen that figure - it was certainly always said to be 29,028 during my formative years.

Are you suggesting that 29.002 was the actual figure that they had 'measured' - or was it, again, a measured figure of 29,000 with a bit added to to 'aid credibility'?

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. :)

Indeed. I must say that I thought it had risen a lot more than that in the past 70 or whatever years.

If you reverse the input/output & pass some current through it, will it run backwards?
Similar to the Ferrari in Ferris Bueller's day off.
