Zs can be measured by a live test but I would expect the results to be that of a lower value than the calculated method of zs=ze+R1+R2

I'm going for a lie down in a dark room
Sorry Mate "you are not an Electrician" how do you know what you are checking is correct?I'm asking - do you think its fudged? Without me having to spend to send another body down to the job and get them to retest. Can anyone see ANYTHING suss about the test sheet I've just uploaded?
I am not an electrician in any shape of form, However I do check figures against what the lads send me on the low and what gets printed on a test sheet. Because I am certain both the CM/QS are pulling the wool over the company.
At the end of the day, I'm there to protect the company and the lads on site, So if I don't check these things then i'm as bad as they are.
those RCBO are very twitchy I often get figures like that but more like 22 @ 5 x. I think its very hard to believe that dado sockets (cct 8 and other rings) upstairs have an R1/R2 of 0.11 must be a circa 10m cct I would have thought more like 30m total giving approx 0.48. What distance does the circuit go to? And thinking about it what you said about the Zs = Ze + R1/R2 is so spot on in every case it looks like its calculated. They could have faked it better by varying the figures.RCD test result times

The R1+R2 for the ringame finals are incorrect and the Zs for these circuits don't tally with the continuity readings
I think they may have written down it was 4mm / 2.5mm but like you I'm thinking the numbers are closer to 4/1.5 which of course is a standard cable size.... however the values of end to end continuity look incorrect for the size of conductors unless the cpcs have been incorrectly sized and should be 1.5 as opposed to 2.5.
Schneider ikq range rcbo s are practically the same when testing the most common ratings 32 amp.The only thing which I doubt is correct is the line/neutral insulation resistance readings which are rarely achievable on an EICR. As for similar rcbo trip times that isn't impossible they are similar, very often Memshield 2 devices will give 39/29 all the time, yesterday I had four in a Wylex NHX all identical. The R1+R2 for the ring finals are incorrect and the Zs for these circuits don't tally with the continuity readings.
It's surprising how many people think that 4mm twin comes with a 2.5mm cpc.I think they may have written down it was 4mm / 2.5mm but like you I'm thinking the numbers are closer to 4/1.5 which of course is a standard cable size.
Having read it a few times while consuming this evening's anesthetic IMHO the report is best redone as it has some inconsistencies.
Not so sure according to the schedule it is T&E as it is referenced as singles in conduit but who knows if that is correct.It's surprising how many people think that 4mm twin comes with a 2.5mm cpc.
It's even written on the drum and most of the time the cable 2x 4.0mm 1x 1.5
I can't see the cert as I'm on my phone.Not so sure according to the schedule it is T&E as it is referenced as singles in conduit but who knows if that is correct.
