Big Clive's "Trashy" meter, unboxed ( Duratool D03047 multimeter )
Fungus:
"Wear ANSI approved goggles when replacing the battery"? :-DD

I have never designed a handheld meter to meet these safety standards and have no idea what is required. Worse, the manufactures don't seem to agree what the requirements are. If that's not bad enough, I question if the "independent" test house monopoly even understands the requirements and will provide unbiased data.
On the plus side, CAT I is a very low energy environment and the risk compared to higher ratings will be lower, assuming the person's education remains constant.

I never said "all meters", or that it was related to counts. It just seemed odd that a 2000 count meter with a 2000V range would stop at 1100V, not 1000V.
If the Uni-T has a 20kV range then it should measure uo to 20kV. I'm betting it doesn't have a range that high though. I'd guess the highest range will be 2kV and it probably displays "OL" if you go past 1kV.
I don't own a Uni-T though or have any gadgets that will generate 1kV-2kV in a controllable manner.

Right, you wrote " Seems to me like a 2000 count meter should be able to display 2000V." There was no mention of range until now. Still, on the back of the meter it states "5. Read the manual before use.". You seem to have been missed this as there is no mention of a 2kV range.

In your case, I wouldn't be too concerned about a particular meter's ability to display or survive to these levels then. Personally, I use a divider rather than attempting to measure voltages outside the range of the meter. Still, I have damaged meters before making such low voltage measurement directly. It's a sinking feeling to watch your expensive Fluke go belly up because of a weak front end design.
Video showing an old and new revision of the DT830 being exposed to 2kV. Double the range of the older and 4X the range of the newest.
