My multimeter has stopped measuring things on the 200mA current range. Turns out the fuse is blown. It's a chunky 1A ultra fast acting ceramic number - size is 10x35mm. I had a look around and the cheapest is about 7 quid. This is rather galling because these fuses are easy to blow... one slip with the meter probes onto a voltage line and the fuse is toast.
Normal 20mm quick blow fuses are about 20p, and looking at the spec there doesn't seem to be much difference in terms of blow times. I could always derate - eg use 500mA instead of 1A. The 'official' fuses are 600Vac and the cheap ones 250Vac... but I'm hardly likely to be using them on 3-phase. So anyone see any problems with substituting a cheap fuse? Or have a cheaper source of the 'official' fuses?
Cheers, Theo
