Love mine too, so much in that little box, Interesting to see, your DMMcheckplus is also a bit low on DCV according to your Keithley, just like mine. although perfectly within the 0.007%
That DMM7510 wow!!!! and thanks for the mention!

Yes it certainly has a lot of functionality built in, not much out there in this price range that can do the same, unless you build something yourself. Thanks for watching and commenting.

I have the old one with the attachment board. That is enough for my needs. But the newer sure looks more professional. Thanks for the video❤.

[@three-phase562]

I probably could have made up an LC board for my old one. The new one is nice, but has certainly gone up in price. Lot of work involved in ageing these though. Thanks for watching.

You 100% need to be doing a rel zero measuring a 100 ohm resistor 2 wire

[@three-phase562]

For sure, I should have done a manual relative instead of relying on the auto zero, just didn't think about that when I was doing the measurements, only after looking at them on the computer.
