connected my mMegger 1553 to a live RCD today when had IR set and locked to test on, straight away pop and a small flash from probe.

Meter was showing >500 and fuse symbol and bleeping.

Switched off and replaced internal fuse at battery compartment immediately but not resolved.

Question is there internal PCB fuses that i have poped and easy replaced?

Yes there are internal fuses BUT opening the cover will invalidate the calibration, I had a similar fault where my fuse symbol would show, over voltage damages the soldered joints apparently, mine had developed a dry joint or similar and would not test anything, luckily for me my cal was up the following day so i opened it replaced the internal fuses but no joy.

I sent it for recal and repair - they repaired it for free! As it was a quick reheat.

Hello DOUGIE1000

From the symbols and sound you have described it would appear the internal protection fuse has blown. This device requires a specialist to replace. We can offer to repair the item or you may wish to contact a local authorised service center.

Hello megger,

Many thanks for your responce!!

However after putting the 1553 back into van and continued testing on my spare test equipment the very next day I took meter into my local edmundson to sent meter away for calerbration and fuse repair, just this afternoon I got a quote from edmunson electrical wholesalers for a quote of £99+vat for 'repair to rcd and loop range the quote also says that if megger was to repair this then the cost would be £270.

I'm not for a second doubting the repair however interested to know what happened? The meter has always been calerbrated nd other than battery compartment always been good to go.

Yes sure I connected a dead test insulation resistance to a 240volt supply however with other metters do they not have satey for us stupid electricians?

A costly mistake I won't do again,

Ps appreciate Meter replying.
