Keysight's new 34465A (6.5 digit) and 34470A (7.5 digit) bench multimeters
<< < (69/145) > >>
Dr. Frank:
If you open the Vertical Scale menu, then Low = 10.000 0 V, High = 10.000 1 V, that's a 100µV span only. See first two screenshots.
It's not possible to manually choose a higher resolution, because number entry is also limited to 6 digits, for 10V, that's 5 decimal places only.

So there's no error with your instrument, obviously.

At 9.999 98 V input voltage, you will get higher resolution, and might specify Center = 9.999 98V, Span = 10.0000µV

PS: Or even more resolution, i.e. 1 tick = 250nV (Center = 9.999 99V), recorded at NPLC 100.
You can even distinguish the A/D's resolution of 100nV (1E-8).
It's also a '465A.

It's nice to see they can be very reactive to the bugs that you find. Please do the 34461A owners a favor and ask them to fix the continuity bug.

Ah, yes, 10.00005 could have been rounded to 10.0001 and this in fact very likely the case.

It would be nice if they'd add another digit, which should fit easily.
