fluctuating IR readings

[james king]

i have completly forgot what this means some one give me a hint lol my mind has gone blank

 

[Smugley]

Do you mean the reading keeps changing the longer you hold the test button down? Or do you mean day to day the readings change?

 

[james king]

as i hold the button

 

[tony mc]

What the readings??

 

[james king]

i havent had any i have just for got what it mean umm ok say 146 then goes to 178 n then back down to 154

Sometimes means something electronic is still connected to the circuit. Had this happen when PIRs are still connected to the circuit.

 

[Guest 004]

damp, water ingress, deterioration of cable, or something could still be connected electronically. Whatever it is, you will need to find it.

when you say 146 178 154 i assume this is M ohms couldnt you just record the lowest reading as they are all acceptable

It's always worth giving the croc clips a sqeeze onto the conductors before testing, or running the socket adaptor in and out a few times before you go ripping the place apart looking for something more sinister....

dont do it while testing or you may get same hair do as me , normally a rising reading indicates that some thing is still in the circuit ,part of the reason why i do the initial IR tests at 250v then increase to 500v save blowing anything up
