(paraphrasing a little here, I don't have the S/M in front of me)
"When removing the Main PCB from the unit, ensure the mode switch is set
to one of the OFF positions. The switch may be difficult to re-align if
this instruction is not followed."
I went with the highly scientific method of "figure out what mode it's
in now, then set the switch to that mode and put it back together again".
To my knowledge, there isn't a CLIP available for it, nor are any of the
parts on the mainboard available separately, except the fuses. Those are
about ?20 EACH (there are two of them). That money will get you a set of
four Littelfuse DMM fuses (two to use and two spares), which work fine
and meet all the specs of the Agilent parts except for breaking
capacity... though I doubt I'll be measuring any 1kA circuits with a
handheld DMM!

I am going to be very wary about buying an old Fluke
instrument now.
Since they don't have spares for old models, and since they use a lot of
custom parts which are not used elserwhere, if there are any problems I
could be in the same situation I am in now.
Yeah, I had a bit of a re-think when I saw the service manual for my
Fluke. One custom ASIC, and a bunch of passives...

I've looked at those on THe Agilent website. They look nice, but without
seeing one and/or a full service manual (which doesn't seem to be
available) I can't comment any further.
