Hi
When I test R1+R2, Ze and Zs and record them on the test sheet, do i record the Zs (as measured at all socket outlets) or do i have to make it fit using Zs=Ze+(R1+R2) ?
Obviously the measured values will differ from socket to socket etc and the R1+R2 will be the highest on the circuit, so the Zs won't equal Ze+(R1+R2) what do i record?
Got my elecsa on Thursday and don't want to fill the sheet in wrong!

record exactly what the meter says
the r1 r2 will quite often not add up exactly with the ze because the current flow of the eli test will power through a connection and an ohm meter wont

That makes sense, the sheet does say 'the highest measured Zs'. However when i did the C&G 2392 exam in february I was told to change either the (R1+R2) or the Zs, but can't remember which?
many thanks
