joe smith | EEVBLOG/UEI 121GW Part 5, Filters, Auto Hold & Reviving a Damaged DMM @joesmith-je3tq | Uploaded December 2019 | Updated October 2024, 5 days ago.
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 this video, we compare how some of the 121GW's filters have evolved. We then have a look at the auto hold, min/max and 1ms peak detect mode and how it compares with other meters.
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.
