HEY INTERNET!

Anybody know the proper way to test a high-voltage self-discharging capacitor?

(Don’t say Mr. Carlson’s, it’s a fine device but it doesn’t test caps like this. Will it show a leak? Yes. That’s by design.)

With a regular meter it tests in range and it’s correctly self-discharging but all that’s at meter voltage which is not exactly this thing’s operating range.

(It’s from a cabinet-fit microwave. Everything works except the magnetron doesn’t actually do anything. I hear the relay click but no zappy. So it’s probably that. But I’m not willing to replace that part because that involves breaking microwave radiation containment shields and I don’t have a microwave detector and I’m not buying one for one (1) microwave repair.)

No idea how to test one, but thought I'd mention one of our customers designed a small product with a tiny six-Farad capacitor.

Not microFarad. Farad. And it's only about 2 cm long.
