If you just want to read the voltage, find a 100 Meg Ohm of if possible
, a 90 Meg Ohm resistor to series with your 10 meg ohm meter. If it is
not 10 meg on the input then you need to adjust the series resistor to 9
times the meter to get 10 to one division where the meter is reading
1/10 of the actual voltage.
Use a powerstat.
Go slowly and be careful.
