High voltage probe and oscilloscope

OK, let me ask the question another way.

If the correct set point for a monitor was 19.3kv and it was set to 18.8kv or 20kv, what would the likely effects be?

Obviously if it's WAY out of whack you'll get x-rays or a really screwed up picture.

In that range, nothing noticeable in the picture.

Once you go too far low (I don't know the exact value for a 6100, but it's on the order of at least 2-3kV), you'll get blooming. But the image typically will look 'ok' over a fairly wide range around the rated setting.

Note that doesn't speak to whatever secondary effects (premature failure, heat, stress, etc) might happen over the long term from running excessively high or low. It's an analog circuit with active components, so it was designed to run at a specific voltage (with some tolerance, usually +/-5% is a reasonable minimum safe assumption for any electronics, if you have no other info).

Low-power digital stuff I don't worry as much about (though anything can technically start a fire). But with higher power things like monitors, I don't take chances, and I stick to the ratings. Better safe than sorry.

Everything is statistical, so there's always a matter of 'how much you can get away with', but with that there's also increased risk, so there are always tradeoffs. And unless you fully understand what those tradeoffs are, it's best not to take chances.

Thanks. A 5% margin of error at those levels is about 900v. You could hit within that margin of error pretty easily with this HV probe if you're careful. You could probably get around 500v of granularity if you're really, really careful but beyond that it's not happening with this probe.

It sounds like this probe will work but isn't really ideal.
