New UNI-T UT892 2000V AC/DC High Voltage Multimeter - 6000 Count - CAT II 1000V/CAT III 600V - DC 2000V ±(0.5%+3) - AC 2000V ±(1.0%+3) - WTF No current measurement - $32 USD Only !!! Is this the "Super Cheap Prodigal Son Fluke Killer" we have all been waiting for? Please note that the YouTube promotional video shows someone wearing electrical safety gloves, so you know what market this "Fluke Killer" is aimed at.

Main inputs are only CATII 1000 or CATIII 600V, but also has 2KV input :wtf: I really want to see this on Joe's HV tests. :popcorn: |
| TCbystander:
All input terminals are then subject to 2kV, the highest rated voltage, protection tests per IEC :box:. The planner might be flying by the seat of his pants ::). |

Just that if you don't have CAT rating then no overvoltages are assumed, which is the standard case when working for example with HV psus. |
| TCbystander:
Without a CAT rating, the 2kV function can't even be used on any locations of the mains including a socket outlet. Not to mention on the standard PV systems which are now CAT III. :-// The meter is claimed to be CAT III 600V rated and 61010-2-033 applies. All compatible terminals are to be tested with the highest rated voltage 2kV for mismatches of inputs and ranges. I doubt they can survive. :o |
