content: I'm in need of another DMM, something in the neighborhood of a 8846A/34401A, must be 6.5 digit and bench. Anything new on the market (no Chinese shit, no Rigol) that that somebody needs to buy, previously unreviewed, for the benefit of the group here?

content: Quote from: kayvee on February 10, 2014, 01:12:57 pmI absolutelyLOVEthe HMC8012, if I had my way they'd release a 6.5 Digit version today and send me one! Even with all of the meters I've got, I need one more, and could use more resolution, so 6.5 it is on this one.Nobody has the HM8112-3, but it is just not even close to competitive these days.

content: Once you have a meter with charting/plotting like the 8846A or the 34461A you will never want a meter without it. The 8846A is a higher precision meter in general (24ppm) but the interface and plotting is much better on the 34461A and it cost a lot less. You can see how handy it was on Daves current source video.

content: I'm not sure, why we would need a new design multimeter every two weeks. I mean the 3458A and the 34410A works without a problem. The 61 is inferior in my opinion, in every characteristics. You buy one and use it for 10-15 years, what is the point? Just because it is new?

content: I was hoping that I'd missed something new, or unusual,. Like a 6.5 digit dmm with built in 8-track player, or beer cooler, toaster maybe.Yokogawa has the 7562 bench unit, but it's pretty dated as well. Hioki has some really nice LCRs, but a max of 5.5 digit DMMs.

content: NANDBlog,Depending on what you want to do with the DMM, the 34401A has problems on some low level measurements as explained here:http://www.gellerlabs.com/34401A%20AC%20zero.htmSo it is perfect for 99% of the measurement needs but if you need the other 1% the 34401A would be useless for you.It would be nice to find a compiled list of all the Bench DMMs produced in the last 20 years with their weakness points so we don't use the instrument for those particular measurements.

content: It is a fantastic meter. However, if you have to pay the full retail price and don't need the portability, you might be better off with a bench meter. Read up about it and compare with the rest.

content: Advantest 871E has 7 1/2 digits of DCV and Ohm display. 5 1/2 for AC which is reasonable because usually AC uncertainty is bigger than 100ppm.It's old but very stable because of aging.
