Testing an economy 7 board?

[DNS1]

Just curious about this one?

If you're working on a property with a night supply and separate consumer unit, how do you do the live tests, without the hassle of having to attend at night?

Sorry if that's a really stupid question, I've just been practising with my MF tester on my own flat, but realised I can't do the heating/hot water supply because it's currently inactive!

If the seals on the meter keep falling off it can be any time of day you like.

If the seals didnt happen to fall off on a strange occasion you would still have your Ze and if you have no RCD on your E7 you only need to calculate your Zs for your final circuits

Limitations box " no live testing of off peak heating circuits Zs calculated on these circuits " sorted Dont just calculate and put them in

It does say on the sheet for the Zs by calculation or measurement, if you have got youe R1+R2 and your Ze you have your Zs, i know, i hear you say its nice to see it on the display but thought i would mention it anyway

yea guv new Megger does the calc for you no need to measure R1+r2 it does it for you altho i do still prefer measured sometimes its not practical

Doesn't on the Easycert certs, just has measured.

Agh yes, give you that one as i use EasyCert as well, but GN3 gives two definitions Measurement (being R1+R2 added to Ze) or Direct Measurement
