On a cheap Chinese multimeter, I can follow exactly but the reading comes down to '1' suddenly (its reads 1 when the the probes are unconnected) and stays there... on two original condensers. On a presumed new 25D4 modern, it didnt work!
I use a digital meter on the highest, in my case, 20 megohm resistance setting.
Make sure the condenser is not in circuit with anything else.
Apply the test leads to the condenser, usually to the case and the one lead or terminal that it has.
Don't have a finger on each of the leads or you will introduce your own resistance into the circuit.
You should get either no reading, or, more usually a "kick" of a reading - say 5 megohm - which steadily decreases to zero.
Reverse the connections. You should get a bigger "kick" which again reduces to zero.
Any reading above zero means the condenser is scrap.
On a Fluke where I can't select the maxi setting, it comes down to zero and then immediately starts hunting again, before coming back to zero.
Can I assume that both of these sound "good" despite the differences in machines?
Haven't got anything which can test the microfarads yet.
Thanks John - at least I can not worry about the coil!
