I'd thoguht of that, but as you saiod there are some 'unknowns' -- what
size of capcitor to sue, whether you need a shut resisotr across the
meter and if so, what vlaue, etc. You may not know what hte meter readign
realy means, particulalry if you don't ahve much experiecne with this
sort of circuitry.
I would start with a1uF non-polarised (not electrolytic) capacitor and a
1M resistor in parallel with the multimeter. Try it on a known-smooth DC
rail (like a battery) and a low-voltage mains-frequency supply 9e.g. from
a small transformer) to ge some idea of the sort of readings you get and
how it behaves.
I /should/ have a 1uf non-polarised disc cap and a 1M ?watt resistor
laying around.
