Wow! That is worlds better than the Cen-Tec 830 Multimeters often 'sold' for free with any purchase at Harbor Freight in the US. I picked up about 5 for that price a while back.
Anyway, that looks like someone said told the manufacture meet some minimum level of safety or get out. The HF ones by comparison are complete crap.
https://www.eevblog.com/forum/reviews/harbor-freight-cen-tech-90899-small-teardown/I think the only safety bits on the HF models are a non-conductive housing (plastic vs metal
), a current limiting resistor on the non-current inputs, a glass fuse, a recommendation to wear safety glasses when changing the battery (!), and a recommendation to have a 'friend' take the measurements for you.
Seriously, from a safety POV the Cen Techs are crap! However, I have on occasion recommended them with the warning that they should only be used for low voltage stuff and never on things that are plugged into the wall.
I noticed that on both voltage ranges that meter says 250V max. Interesting. I wonder if that is actually because the voltage range didn't meet a safety target or because they only used 250V fuses in the current ranges. It's cheaper to say don't test over 250V (which is probably a non-issue for most buyers of this sort of meter) vs buying better fuses.
