    Earth Continuity Testing

    As part of my new job, we are required to test existing DC Power Racks for Telecoms. We are told to carry out a earth continuity test, then a IR test, then a ELI test. I may be getting a little complacent the older I get, but surely Earth Continuity is slightly OTT? I mean, we're proving an...

    3P continuity L1 Earth

    Quick question for someone... Recently came across 3phase industrial heater, changing over a faulty isolator, in terminal box where equipment cable meets supply... I have continuity between L1 and Earth but nothing between L2 and L3 and earth. Disconnected earth from source and still the same.

    Varying continuity readings

    Hi all, I am using a Fluke 1662 with fused test leads. I find when doing continuity tests such as R1+R2, as the test button is being held the result fluctuates dramatically. Both increasing and decreasing. Seems to happen on insulation resistance as well however not so much. I also find after...

    Different reading when using continuity and IR?

    This is one of those slightly embarrassing questions that I feel I should know the answer to. I can feel the answer lurking under my skin but it's just not surfacing and needs a push! Pre-work visit for a CU change. There was 65K Ω resistance between N-E on the continuity setting, however when...

I’ve put this in the EIC for the new board that no cpc for lights, advised client that needs rewiring and...

    Voltage present when fuse has blown with no continuity.

    Can anyone help with the below, there's probably a simple explanation but it's driving me mad. Why I would be still measuring 24v DC at a 24v motor terminals after the fuse had completly blown? And there being no continuity across the fuse at all? This was also the case on the terminals of a...

    recording of earth continuity results for appliances with detachable leads.

    When testing appliances with a detachable IEC power lead, what's the recommendation for recoding the earth continuity value, do you record the higher value including the lead resistance, or exclude the earth resistance of the lead from the actual appliance. This assuming that the lead is tested...
