Some cut.

So, might be time for a new drill.
Early lithium batteries weren't up to the task.
Are the newer ones reliable?

More cut.

Take a look at the "other" on Ebay once you decide
what brand and such you want. I got a good deal on a
return out of the package.

You probably will not find a voltmeter/multimeter that goes over
around 1000 volts. Or not at a reasonable price for most.
Has to be one. obviously. Otherwise, various companies would have no
way of reliably testing their HV output devices to ensure it is
providing enough juice to energize neon and/or a magnetron tube.

I don't remember if it was a Fluke but we used a high voltage probe:

The products were dielectric preheaters for the plastics industry and
were basically a 15 kW Hartley oscillator with the plastic material
placed in the tank circuit.

The RF voltage measurement was more primitive. There was a homemade
device that was two brass balls on a screw. Put that in the cavity,
crank down the top plate, and pull the strings until it arced out.

RF leakage was determined by a fluorescent tube on a broomstick.

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?

Yeah, that's what I used it with, a Simpson 260.

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.

The ones I have are simply a resistor of about a Giga-ohm in series.
They were designed back in the day when the input standard was
20K Ohms per volt.
For a High-Z meter, shunt the meter (creating a voltage divider) until
the voltage reads correctly.
