MULTI-MEASURE bug - If I understood correctly what the video was showing (when going to 100V or 1kV range), then yes its a known hardware issue that will be resolved on the next revision.
Personally I'm not so worried about this 36mV jump (on 100V range) to 2.4V, 2.4V is not present on the terminal (it's still 36mV) (the voltage terminals were not floating, 50ohm)
Maybe you can shine some light on the limitations of MULTI-MEASURE of voltage and current (excluding the 100V range bug)
In this thread we checked other DMMs (not Keithley) and also much more expensive DMMs and they all have this xx mV reading when running 1A through the device.
So that seems to be a common thing to happen, that is how it should work.
But how does Keithley or any other manufacture then say voltage can be measured while current is running through the device? Seems to me the best you can say is it can be done but then the voltage is completely out of spec.
Anyway it's better to have it and understand what the limitations are than having it disabled.
From what I experience it's rarely a good idea to do both on one device hence why I don't really worry about the 100V range bug.
One other question: to request software improvements or report bugs what is the best way to do it so the info gets to a place were it will be logged and read by the software developers?
Although the
https://forum.tek.com/ forum seem to be the place, it doesn't seem to be read by Keithley.
(I would expect at least an "We look into it" reply within a few weeks when a bug is posted)
Thanks
