Thanks for a great demonstration, I bought one, kit, for about four bucks, the red one, a couple hours to assemble, calibrate as per your video, and I've cleaned up one box of unknown parts, and segregated them. I would've paid a hundred bucks for one of these, twenty years ago, nice to have now. Thanks again, great demonstration

I really need one of these testers. The one on the right seems to do the same job as the one on the left, but the right one seems better to me. Thanks for doing a showdown between them. It’s helped me make up my mind. I’ll order with your link if there is one posted. Thanks again.

You can easily calibrate the one with the yellow PCB. Just insert a jumper between 1-2-3 like the other and press test, it will automatically go into calibration

I am only thinking...: over the "do not dispose" symbol, there are two passthroug pads. What are They for? In some pre-assembled ones, there is a hole ("window") that claims to "read IR codes from remote controls"...but I could not find anywhere info about that. Anyone has?

Not sure it matters, but you have a fresh battery in the M8 and a tired one in the M12864. Could affect accuracy. I have an M8 and a GM328, the latter an upgraded version of your M12864. Both these units came with problems. The M8 got stepped on before it arrived and the display glass was broken. I ended up replacing the display - not exactly an economical repair but it did teach me a bit on how to repair these units. The G328 case was hopelessly mis-fit to the circuit board and had to be Dremel adjusted to make it fit. If you're the bumble-fingers type you probably shouldn't try either of these repairs. The G328 also uses a smaller font which allows more data to appear on the screen, which I like. As you say, take the accuracy with a grain of salt, but these units do help in diagnosing good vs bad and in identifying unknown components.

Good point. I also got another high value cap / inductor meter and after a few months it quit. Seems I will be trying to replace a chip on it per others on the internet with the same problem. Too bad they don't put more effort in quality in these things. I'd rather pay a few bucks more and have them be reliable.

I've been thinking of putting together some electic devices and can get boards and the parts at good prices. One of these units maybe very helpfull to ID parts, so less like to put in wrong ones. Even years ago with better eye sight, it could be hard to ID alot of parts, alot are smaller know too.

I used the capacitor they supplied. There are lots of numbers they show on the screen when it is calibrating, I assume some are the internal values of the device. So when it says 100 nF, it might be the base line of the device, don't know. The instructions don't explain what is being displayed.
