I found a 400M ohm high voltage MOF resistor at a swap meet. I mounted
it in a long plastic box. I used banana jacks for the in and out
connections. I connected a precision R and a 20 turn trimpot across the
output of the divider. Feeding 1000V in, I adjusted the output for
1.000V, which calibrated the multiplier box for x1000 . I can measure up
to 30kVDC accurately with my Fluke DMM. .
- later, Igor
