Hi all

I'm sure I saw in PE that there is a device u use with a multifunction tester to do your monthly checks on to ensure it's running ok month on month

Does anyone know what it is ?

Thanks

Jack

calcard. loads on ebay. or, what i do is use a particular circuit at home and take readings form that, once a month and record them. any deviation from the last reading would show a drift in the MFT (assuming the dogs aint chewed a cable)
