Hello JonE
If the meter reads "1" then you have exceeded the range set. So if you get a "1" on the 100MOhm range then the leakage resistance must be greater than 100MOhms.
If the meter climbs on the highest range but does not reach "1" then the reading will be the resistance.
This is all just only at the meters own regulated voltage, probably 5 volts.
Hope that helps.
Adrian.
Edit: If the meter reads minus then the capacitor has been charged opposite to the way you are now reading it. Just short the cap and start again. The Magneto Guys suggest over 10M is ok.
