Our newKeithley 2100DVMs are nightmares. The default setup is almost
unusable, the menus to change things are incredibly obtuse, and the
settings *can't be saved*. I never turn mine off.
All my settings are saved in EEPROM!
Every time they're changed, or is there an explicit save command? I
like battery-backed sram for saving a current machine state, because
it's fast and doesn't wear out. EEPROM is good for explicit setup
saves.
:-)
What's bizarre about theKeithley 2100is that it does have a save
function that saves to nv memory, but the most needed settings don't
get saved, and the really obscure ones do. It always powers up at 60
display updates per second, so the rightmost 3 or even 4 digits are an
unreadable blur.
Pity: it's electrically superb, but the user interface wrecks it. Yet
another example of good electrical engineering trashed by clueless
programmers.

I saw this post _after_ I bought my Keithley 2100. It's unbelieveable.
I started writing a review on it as soon as I got it, which I will
turn into suggestion list for Keithley. I don't know what the rest of
their stuff is like, but whereas my first Fluke made a big impression,
this has probably put me off Keithley for life. I'm really angry that
they waste keys, but put "hold" on a shifted key!
When yours is rapidly updating the display do you find it to be
erratic? I mean that the display has regular pauses, like there is
some kind of I/O contention or buffer filling up. It's not what I
expected.
My review is nowhere near ready yet but please let me know if you
think I've got it wrong so far! This is my first review of anything.

What have you compared it with to rate the electrical performance?
Sadly this is the best meter I have got accuracy-wise, so I have
nothing to compare it to. It would be comforting to know that I
haven't completely wasted my money.
