[Amps] Re: HV Voltmeters

[David & Wendy Dodds]

I opened the meter and, true enough, there is a shunt in it. It's a weak-looking affair - about 20 turns of roughly .5mm dia. wire. (not sure of the material - same sort of colour as galvanised steel?). However, there's no indication of what the FSD is without the shunt. It's marked  "MH-32" and "class 2.5". I don't know if that's anything more than just a product code.
