Hi all,

I was wondering if anybody has come across this fault before that I seem to be getting with my Megger MFT1552.

When I measure the voltage it reads around 260V (iv tried it in a few different properties). Then if I switch it to the RCD auto test or any of the RCD individual tests it bumps up to over 300v, flashes and doesn't let me continue. When I swotch off the socket/supply it does go do to 0 so its not registerong a voltage when there isn't one it just seems to be registering the voltages really high

I really don't want to have to call it a day with the MFT as its a great bit of kit albeit an oldey so was just wondering if anyone has come across this before?

Thanks for any info :)

Send the MFT away to Megger and ask them to check operation and a costing of any repairs that they uncover, if it's BER then time for a new one.
 
try The Calibration Centre at Stafford. They provide an excellent repair service at reasonable cost.
 
Try Test Meter, forum sponsor, they provide a good service.
 
So just an update... and I fear I may be required to hand in my electricians card as well as my man card here.... what i thought were new batteries were dead... changed the batteries and its showing correct voltage..... i mean there are no words!!!!!!

At least you admitted it, well done and a cheap fix.
