Hello,
I would like to ask owners of the 121GW: Would you recommend this meter to be purchased in 2019 ? Are there still any software issues that still need to be resolved ? Are there any missing, unimplemented, features ?
Thank you !
Long time lurker, thought I'd chip in a few opinions about the 121GW.
I have about 30 different multimeters going back probably 75+ years (got some from my grandfather) and the 121GW is my most expensive/newest one. I'm just a casual tinkerer/hobbyist.
What I like about the 121GW is that it is my most modern DMM (Bluetooth/logging/apps), I can update the firmware and there is a very active community for it. It isn't perfect, nothing is. I use it regularly, although not for everything. You do want multiple meters since each have their optimal uses and you also will need to check them against each other.
All the issues with the 121GW are basically known at this point and beaten to death. What impacts me the most personally? Resistance measurements are painfully slow. I use my Micronta (22-167) if I need speed. I recently obtained the DMMCheck Plus and like a kid in the candy store put all my meters through their paces. The 121GW will take 17 seconds to measure the 4 precision resistors (v1.58 firmware). The Micronta was 5 seconds (as was the BM235). It's a manageable problem, but there nonetheless.
My three favorite DMMs right now are the 121GW (workbench), the Amprobe AM-47 (without the rubber case but with the VC3A nylon case, travel/work/backpack), and the UT210D (automotive/house/shop).
