Ze Zs and R1&R2 readings of 0.00 ohms.

mamba · Feb 4, 2014

A measured test shows a reading of 0.00 ohms. I have always when got this reading recorded it as 0.00 ohms on any test results sheet. As I have always believed it is a reading and must be recorded as such, I have also seen it written somewhere in either the NiCEiC Inspection and Testing Book or in some other reference.
Having a debate .... with my supervisor / principle duty holder who is arguing that must I record a measurement of 0.01.
I know at end of day splitting hairs on 0.01 ohms, but if anyone knows where this is stated or has their view let me know.

That's a short (in length) circuit!

Confused what tests are you conducting? your title ZE,ZS, R1+R2 is a little missleading

It is because it cannot have zero resistance. unless it is a "superconductor", it is just too low for your measuring instruments resolution.

I was Taught to put < 0.01, or less than the whatever the lowest resolution of your instrument is.

First off, throw away your NICEIC book.

I was taught not to record 0.00 (essentially meaningless), put down 0.01.
I'm sure it's in GN3 somewhere, possibly an older edition.

edit, superconductor, Like it 68!
