I'm trying to measure DC voltages in the range of 100-1000V, however a
normal multimeter with a 10 megaohm impedance won't work because it
draws too much current (my device is very resistive and runs only
10-50 microamps). I have even tried a high voltage probe and it still
draws too much current. Does anyone know of a device (or how to make a
device) to measure high voltages (100-1000V) while drawing only
nanoamps of current?
I have also tried putting a 2.5 gigaohm resistor in series with the
multimeter and that doesn't give accurate voltage measurements.
Thank you in advance for your help and ideas.
