  • It's been over two years since I looked at the 121GW prototype. I wanted to allow Dave and UEI plenty of time to address the problems before reviewing it.
    In Part 3, we compare how the 121GW behaves against other DMMs when measuring small capacitors, currents and voltages. We finish this segment running a few higher voltage tests.

    One of the problems I ran into back in 2017 while looking at the prototype was with the VA mode. Roger, who ran the YT channel KainkaLabs, repeated my tests. He did a really nice job explaining the problem and how to work around it. I doubt I will go over this problem again, so if you're interested, I suggest you watch his video.
