Wouldn't that be a problem? --- End quote --- Not if it's plainly clear which measurement mode you're in. |

Thanks everyone! I'm planning this as a gift to my grandpa, so idea of used equipment is not really nice, imo. He requires rotary knob, because he has nice "finger memory", so can easily remember the positions, without having to look at the tiny labels. So this is why I skipped that Vici/Victor model (which is also auto range). He had something similar, with auto range and buttons (Amprobe, maybe), he didn't liked it, so gave it away. He does not like auto range, so need manual range. The benchtop requirement comes from the smaller work area, so he do not want DMM on it, but prefer to put it in on a shelf behind, so hence the requirement for larger digits. |

I dunno, I would be more exited about getting gifted a 15 year old Keithley 2015 than a brand new Keysight 34460A Rotary knobs are not as good as you might think. When they have a lot of positions it can be hard to tell in what position they are without looking at it. Most bench DMMs have a dedicated button for each function so once you get used to it then it becomes even easier to switch modes by muscle memory. If you go for old enough ones they will even have the clunking mechanical selection buttons that stay pressed inside(like on a audio cassette player), so you can see what function is selected. More of my issue with them is that i commonly use 3 different bench DMMs and the buttons are in different spots. The ones this old are also usually manual range too. Trust me anyone who has been in the electronics field for many years has a high level of appreciation for old high quality test gear. The new latest and greatest 3000$ bench DMMs are not really all that much capable than what they made 20 years ago. This is why all my high quality DMMs are old ones. The modern ones i own are mostly the cheep handheld DMMs that i don't need to worry about breaking when working on top of a ladder. More of a issue is that getting your hands on a good old high quality DMM involves a lot more work (looking on auction sites, buying cheep non tested units, potentially having to repair it once it arrives, fixing cosmetic issues etc) |
