IR readings Puzzeled

[ianphilip007]

hi there

carried out IR test on radial lighting circuit today. L-N 700MOhms N-E 650Mohms L-E 320Mohms just wondered why the L-E would be nearly half the value ???? ( test carried out at 500v dc, TNCS system circuit disconnected at board)

If you are looking for reasons why they vary so much

Then check how good the batteries are in the meter, if they are ok then check the test leads had quite a few which failed at the plug through the continuous flexing they get

maybe thayt's why my joints are failing... all this flexing.... not just bending to pull cables, but lifting beer as well.
