Hi All,


I recently picked up a couple of diodes (5" black plastic rectangular rods) rated 200 ma @ 80 KV. A standard diode checker doesn't seem to work with ones this big. Is there an easy way to test them before they go in the circuit?

I like to test HV diodes with an electrostatic generator and an electroscope:

In that case I was only interested in the leakage. The electroscope saturates at 5 kV. Testing at 80 kV would be more difficult.
