    And one other remark about the Uni-T meters (all of them!) and a lot of other cheap meters: do not try to measure mains voltage with those! Officially they are capable of doing that, but the protection inside the meters is way below adequate. If you make a short with the test pins (or a high energy surge comes through the line at the moment you're metering it will blow up in your hands!

    So as long as you're testing low power devices, you're ok. Otherwise I'd really advice to save a bite longer and buy yourself something proper (Fluke , Keysight and what I saw of Brymen is built proper as well).

    @DavidZH You're right. Thanks for bringing up the safety aspect, it should have been done earlier. I guess online teardowns will show if the DMM level of protection corresponds with the specification. Of course the fault current rating isn't near the level of high-end professional tools, but hopefully satisfactory. The greatest risk I can think of is if someone uses it to measure on the wrong side of their common household fuse (10-16A), but then you can argue that fiddling there without enough knowledge or skill is the first mistake.

    @kenci Blowing up something then survive and clean up doesn't sound too reassuring. But real tests are always valuable so thanks for sharing.

      The safety aspect is mentioned in the videos I linked and in several of the threads. Yes, it is important if the multimeter will be used for measuring household mains. I don't plan on measuring anything above 24V, and most often 5V and lower so I am not that concerned.

        In some sense I guess there's a dilemma that you'll need a better tool the less you know.

        Btw, I'm now a proud owner of the super cheap ut33a. At 10A socket it says "Unfused". FYI I've plugged that socket. Useless and dangerous.

              @alexsh1

              $270 (including shipping from Poland)
              Looked like it never ever had been used. It still had the plastic shield on the display and everything was wrapped up nicely without any scratches or anything.

                @hek Still expensive IMHO but this is Fluke's price. In fact it is 1/2 what the multimeter costs normally

                  Late to the party...., but I absolutely love Fluke. I have several and they are build very well.

                    I have to agree... I think you'll need at least one Fluke.:yellow_heart:

                      Temped by EEVblog BM235 Multimeter especially given it comes with some nice silicone leads.

                      https://www.eevblog.com/product/bm235-multimeter/

                      The flukes are very nice though!

                        I'm looking for a one that's a bit cheaper. And so a voltcraft VC 130-1. Is that a decent multi meter for a hobbyist?

                              Anyone reading this post, and thinking of buying Multimeter , I recommend buying a like this one,.
                              Because you cannot measure AC current using that traditional multimeter like this one.
                              Accuracy of clamp is greater than the traditional one, you can also detect the flux or EMF using clamp meter. It will be very usefull in detecting live wires with current and in the projects related to coils as it can detect EMF.

                                It depends what your main usage is: the clamp meter is not very handy on a desk for example.

                                    @Nca78 Yes it may be a problem to measure currents in micro amperes but normal multimeter can't ever measure the current in milli amps accurately.

                                      I have a completely automatic one, and I love it. It doesn't have a dial you have to turn to determine sensitivity.

                                      All it basically has is an on button and two leads.

                                      This gives me much more assurance that I won't fry the multimeter, so I use it a lot more.

                                        OK, my best recommendation is Brymen BM869 (with logging) or there is a model without logging.

                                        I have also supported a kickstarter project for a new Dave's multimeter EEVblog 121GW - https://www.kickstarter.com/projects/eevblog/eevblog-121gw-multimeter

                                        There is another model EEVblog BM235 which I can highly recommend.

                                        I have changed my mind about Vichy VC99 multimeter. Mine failed after a year and the build quality is just poor - you would not want to test even 240V with it. However, it has been very accurate in the beginning and extremely cheap.
