When I worked on CRT TV sets, I had a high voltage accessory

Thanks. I'll check this out in more detail. Which meter did you
pair it

with?

That's not the exact probe. The one I had fit different meters and
I bought it at the electronic supply house in the mid 1970's. The
meter probe plugged into the back of the HV probe adapter and had
a multiplier that you applied to the meter readings. Inside the
probe was a long replaceable high ohm value carbon resistor. I
used it when working on CRT color TV sets which put out upwards of
30-40kvdc to the anode connection on the CRT. It worked with a
Simpson 260, VTVM or DMM.

Ahh. Thanks for the valuable information. I figured some high ohm
resistors would be in play; much like an electric fence reader, then?

They're not fancy. Given the era when I used them there wasn't any
active circuitry involved.

The hardest part is getting a resistor that won't flash over, hence
their length. Other than that it's a voltage divider with possibly a few
bells and whistles.
