I am happy to be able to participate in the free beta test program for future true Keithley customers.  :-BROKE  :clap:  :rant:

I understand the reason for the glitch in the digital track lying next to the divider? Or is it more complicated? Can we get more information to fix the problem ourselves?  :-/O

I understand that the glitches that I saw in the 100V range in the normal measurement modes are of the same nature?

MegaVolt:
Different numbers of decimal places depending on the selected screen or the value of a number.

Kleinstein:
It is probably the values to show. They seem to use the same number of total digits. So one more digit resolution once below 10 V. For the average the higher resolution may actually make some limited sense.

The peak to peak and StdDev values still have some digits well in the noise / fantasy. It is not a big deal, but ideally there should not be much more digits than actually real. If at the edge one more digit can be good - so the average could get one more digit, while the peak to peak and StdDev case should get less.

* Does not support measurements for Pt1000. No solution.

Both the DMM7510 and DMM6500 should be able to use a PT1000 RTD.  Change 3/4-Wire RTD to "User" and set RTD Zero to 1000.

I've just posted a couple of bugs around the temp measurement stuff in the Tek forum, so I though I'd add them here for completeness.

(a) Using a thermistor, with 1.7.0e the display reads in kilo degrees ... not very helpful! It was fine in the older firmware.
(b) Using a PT1000 (not sure that's relevant), with 1.7.0e the display reads "-DispNan-" ... graphing is fine, so the value is actually read ok. Haven't tried this in the older firmware.

I'm assuming these are generic temperature display problems with 1.7.0e firmware. Quite how you can release a major firmware release without testing this stuff is beyond me!

I've also found quite a few display issues, but in the scheme of things they seem less important. I must say my first impressions (after only 2 days) is that the hardware seems great, the capabilities (esp the triggering stuff) are superb, but the firmware quality is awful!
