    fluke 1652c continuity readings

    Does anyone else have problems with there continuity readings my readings never seem to be stable for example a newly installed ring end to end resistance on neutral and line ill get .46 and then a reading of .04 on line end to end the leads are always nulled and I even check readings on calcard...

    Ze Zs and R1&R2 readings of 0.00 ohms.

    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...

    Megger 1730 erratic readings

    I recently bought a megger 1730 and i`m getting some weird earth loop readings using the no trip function. I know they can be a little higher at times when taking a "no trip" reading as my old 1552 was always a little higher too but these seemed well out... I only got the meter this week (Used...

    Hate my new job!

    Just landed a new job. It's only been 4 days and I'm about to quit today. The role involves working on gas meters (wall testing). They want me to manually take readings from 20 gas meters on a wall. Each meter has about 15 data information which i need to type into a tablet held by my left...

    Trip readings too high on ground fault relay with Toroid sensor......Help?

    Hi there, Have been carrying out testing on some 3 phase sub-DB's that have outgoing supplies to 3-phase DB's for accommodation blocks. My problem is to do with readings I'm getting on a ground fault relay which has been set to 300mA. Basically, the incoming cable to the Sub DB ( 4-core 25mm...

    fluke 1652c continuity readings

    Hi all I keep having problems with my fluke the continuity readings are all over the shop never stable I always check my readings on a calcard before testing and when nulled I get correct reading i will test it on calcard 5 minutes later and it's half an ohm out so never know if I am getting an...

    High zs readings low ze readings

    Hello I've recently been called to a job regarding high earth fault loop readings through out the house they've got an old style mk consumer unit with a 30ma 60a main switch mk LN5760 the supply side of the rcd had good readings and but the load side readings were more than double that of the...

    RCDs raising zs values

    Was at a property toady which I've done previous work before including fuseboard change. All i did today was change a few socket plates over for new ones. Took some Zs readings and noticed they were very near the limit of being acceptable ie: 0.92, 0.98 etc. Took a Ze at the board with main...

    Acceptable readings for a NEW installation

    OK peeps I have just tested an 185 4 core SWA, and have got readings of 40 Megs on L2 to earth and L3 to earth. Although this is accepatable according to the regs, I feel it is unacceptable as a NEW installation, and indeed there is evidence of water on some of the switchgear, which clearly...

    Socket ring readings. R1+R2 approx half r1, r2

    I havent come across this before, wondered if its common and what it signifies in the ring. Remeasured 3 times and got within 20mohms or so each time so pretty sure its not a zeroing the meter thing. 2.5:1.5 TW/E ring. I went around all of downstairs rooms, did min of few sockets in each room...

    EICR - high readings

    I am part way through a condition report for a customer. The house is generally in good condition but the electrical installation is quite old. Although the rings are properly installed as ring final circuits, the 2.5 mm t and e cable is stranded and the Cpc appears to be 1 mm rather than 1.5...

    Zs readings on TT system

    Hi there, In the process of testing a large property. TT system. Ra is 58.4 ohms so all good. But starting to test Zs and getting readings of 0.18 on sockets? Why would this be?

The main supply is coming up through the floor and into the main 3 phase service head......along with this is what I would say...

    Different continuity R1 and RN readings on ring

    Changing a CCU and reconnecting existing wiring (twin and earth) = did a N - CPC IR test for earth leaks prior to dismantling the old (BS3036) unit for obvious new RCD trips; all ok. However, on ring circuit the continuity end-to-end readings of the R1 and Rn are 0.3 ohms different; 0.41 on...

    no cpc continuity on ring final, strange readings !

    Good Evening all, Been at a property today starting intial tests for a board change tommorow. There are two ring circuits, on one of the ring circuits i had an open circuit on the cpc. Live and neutral where fine 0.4/0.4. I started to locate the break by splitting the legs and joining the live...

    fluke mft

    Forgive me but I can't search existing threads as the app just crashes each time. I'm looking at fluke mft's and would like to know which is best, why and of any issues. I did have one years ago but it did give some odd readings now and then and don't really want that again. Those who can't...

    ELI on no trip with Megger MFT

    Does anyone have issues with this test and how accurate is a No trip test? I find my readings seem to change a fair bit testing the same circuit a few times. This is using a 1730.
