joeqsmith would have a field day with this meter; starting at about 33:30 I put the non-volt ranges through a ring generator (90VAC, 20Hz, but the load probably took it down to about 40VAC) and the meter goes completely haywire.
I have not seen any other reviews for this meter. Someone had pointed it out to me in a YT comment. They had a 3D drawing of the meter and I could see it was similar to other low end meters I have looked at and figured why bother.
I don't know your language but I watched your video anyway. It's funny how the brain will put a story together just based on your voice and gestures. There is not much to these handheld meters which also helps in following along.
Yes, that input trace to what appears to be the ground plane looks bad. The large fuse you show appears to be the same that was in the Meterk. The end caps will just pull off on that one. You should find it is filled. On the Meterk, the smaller fuse was NOT filled. Contrary to what Fungus believes, not all ceramic fuses are filled safety fuses. You would need to pull it apart and have a look. It took a while before I figured out that you were using a telephone ring generator. Google pictures to the rescue.
In the end, I get the feeling there was not a lot of praise coming from you.
Thank you; that is truly an honor to have you watching something from me - I learned so many nuggets from your videos. I would love to have the energy and time to create decent captions, but unfortunately this is a full time job on itself. I could do dubbing as well, but unfortunately this means almost re-doing the video. Oh, well...
Regarding the details, you are right that I had a bit of trouble with the input traces and their lack of creepage, but I was very impressed by the quality of the PCB material - the copper is quite thick for your regular cheapie meter, and the amount of via stitching is impressive. I had my suspicions about the fuse, their lacking specs (less than nominal 1kV) and their ludicrous 100kA claim (although it may be mildly possible at the rated 380V).
I also commented on the very lonely PTC to protect the inputs, which is located after the switch (something you mention in your videos and I learned to pay attention), as well as the vias on the middle of the wiper contacts, which may wear out after years of very intense use.
I have been using the ring generator (a BlackMagic module scavenged from an ancient Gandalf ISDN modem) for quite some time when testing the AC range of my meters. However, it was the first time I put it to try to break a meter - it has low enough energy to not blow it on my face, but high enough to show my audience the reason why protection is important. I make a statement on a caption of what would happen if a user accidentally connects the probes in an outlet, considering it was behaving so badly with such low energy.
Overall I think you can put this meter to very good use in electronics if you are on a shoestring - that is the case of most of the audience, given that import taxes in Brazil are ludicrous and an A-brand can easily go to 2~3x the price. With that scenario, folks tend to be a lot more forgiving of a meter's issues and may take some dangerous risks. But you are right that I wasn't much cheerful due to all the issues shown.
