The UT892 looks like it's tailored for working with VFD's, hence the HV and LPF function. It just seems to be an extra 10MEG resistor array switched in on the extra banana jack input to get the 2kV range. I'd dislike having to switch to a special HV range, and move the input jack for the HV range, gee I wonder what could go wrong there :palm: If your finger is near the normal input jack but you're on the HV function... surely no shock hazard right? Overall I find Uni-T intentionally cheaps out on input protection, it's too bad the brand chooses to be fragile. They do know perfectly well how to do it decently as seen in their OEM offerings. |

I´ve got serious doubts about the 2000V range on a meter which costs "nothing". I´ve started a thread not long ago because I´m (still) looking for a meter which can measure 1500Vdc at least. Because we got a new supply at work which can deliver 0-1500Vdc and I don´t want to play around with HV adaptors. There are very few meters avaible, like this here for example: Beha-Amprobe HD110C Costs more than 6 times, it´s very "bare" and got 1000V CAT IV... Then the UT-892 come along, for 42 bucks... I got doubts. ;) |

I have my doubts about their safety ratings but in the lab I'm sure it will be adequate. Promotional video from the company: |

Google AI is impressive. --- End quote --- yeah smart bot.. one example is... the-sv4401a-low-cost-vna-($350-usd) the impressiveness is that the bot can make hundreds of pages of VNA softwares + doing some rigs and testings... ;D i'm one smart bot that can make jokes and argumentations. whats wrong with bot promoting some new products? there are many bots here doing just that since the beginning, why the hate and bitterness to uni-t products? ;) |

The question is... Is the UNI-T UT892 a good buy at $32 USD? What are the advantages of owning one? What are disadvantages of owning one? What kind of person should buy one? What kind of real world applications exist for such an instrument? At only $32 USD it makes the impression that it might be the "safest cheap option" to measuring HV. I cannot imagine that HV safety has been completely compromised in a meter that measures 2kV. 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). I suppose you could construct your own 10:1 external attenuator to achieve similar results. I love the "RED LCD BACKGROUND" to warn the user that they are measuring over 1500V. P.S. The attached image illustrates this meter being connected to a 3-phase electrical circuit. It must be safe. :wtf: |
