The New UNI-T UT892 2000V AC/DC High Voltage Multimeter is the real deal !!!

Here is a real life application how this brilliant piece of engineering should be used.

Look !!!

High Voltage wiring !!!

Impressive Red Electrical Safety Gloves !!!

I'm all wet between the legs thinking about this beauty.

What kind of person should buy one?

a person wanting to commit suicide ?

I do not I hate or harbor bitterness towards UNI-T.  I have certainly provided them with more opportunity to show case their products than any other brand.  That also suggests I have invested more of my own personal time with UNI-T than any other brand.   I've collected a lot of data.  We all know that data can be a harsh and cold mistress, void of feeling.   

I'm not sure what my first posts were about here but I doubt I was attempting to promote any products.  Seems I was more pointing out the idiots who where jumping their hand held meter's fuses with wire.   

Mechatrommer:
the idiots still around whether you like it or not... havent heard bots with emotions though, maybe AI got too advanced nowadays ;) since i already posted...

--- End quote ---
for normal household use, yes.


--- Quote from: jhoffman on August 28, 2022, 10:01:28 am ---What are the advantages of owning one?

--- End quote ---
you have one extra DMM at affordable price.


--- Quote from: jhoffman on August 28, 2022, 10:01:28 am ---What are disadvantages of owning one?

--- End quote ---
getting fooled that really think it can measure 2KV safely


--- Quote from: jhoffman on August 28, 2022, 10:01:28 am ---What kind of person should buy one?

--- End quote ---
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.


--- Quote from: jhoffman on August 28, 2022, 10:01:28 am ---What kind of real world applications exist for such an instrument?

--- End quote ---
browse "normal multimeter purpose"


--- Quote from: jhoffman on August 28, 2022, 10:01:28 am ---At only $32 USD it makes the impression that it might be the "safest cheap option" to measuring HV.

--- End quote ---
certainly no. it actually a red flag. but then with chinese ingenuity, anything should be possible.


--- Quote from: jhoffman on August 28, 2022, 10:01:28 am ---I cannot imagine that HV safety has been completely compromised in a meter that measures 2kV.

--- End quote ---
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.


--- Quote from: jhoffman on August 28, 2022, 10:01:28 am ---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).

--- End quote ---
thats the theory..


--- Quote from: jhoffman on August 28, 2022, 10:01:28 am ---I suppose you could construct your own 10:1 external attenuator to achieve similar results.

--- End quote ---
yes if you are well versed in creepage and clearance... and components rating.


--- Quote from: jhoffman on August 28, 2022, 10:01:28 am ---P.S. The attached image illustrates this meter being connected to a 3-phase electrical circuit. It must be safe.  :wtf:

--- End quote ---
3 phase has nothing to do with 2KV.

PartialDischarge:
Well, since I do a lot of work with HVU psus working in the 1000 to 2000V range I decided to buy one, I will test it before using for accuracy and internal clearances, and I'll use it if I like it.
