since i already posted...
Is the UNI-T UT892 a good buy at $32 USD?
for normal household use, yes.
What are the advantages of owning one?
you have one extra DMM at affordable price.
What are disadvantages of owning one?
getting fooled that really think it can measure 2KV safely
What kind of person should buy one?
anyone who dont own yet a DMM, or just want to add the collection, or who think has a thick skin to risk the life on 2KV with cheap DMM.
What kind of real world applications exist for such an instrument?
browse "normal multimeter purpose"
At only $32 USD it makes the impression that it might be the "safest cheap option" to measuring HV.
certainly no. it actually a red flag. but then with chinese ingenuity, anything should be possible.
I cannot imagine that HV safety has been completely compromised in a meter that measures 2kV.
it possibly is for $32 DMM. but there is work around other than the not recommended short wire replacement for fuse, you should wear safety glove and boot too. 2KV high energy is not something forgiving, sometime even any brand of DMM is not required in death equation.
Being a 6000 count meter suggests (see attached image) that can potentially make measurements up to 6kV if no over-voltage breakdown was to occur in the internal 10:1 attenuator (2kV input).
thats the theory..
I suppose you could construct your own 10:1 external attenuator to achieve similar results.
yes if you are well versed in creepage and clearance... and components rating.
P.S. The attached image illustrates this meter being connected to a 3-phase electrical circuit. It must be safe.
3 phase has nothing to do with 2KV.
