Hi,
They were out of warranty, 2 to 3 years old.

That´s a very interesting information. I´ll ask a lot of questions about 
warranty now... How old was the Keithley?

>> Why would you want to use ANY of those DVMs?  With just a little patience you can buy an 8.5 digit HP3458A on Ebay for under $3000.  It is the best DVM ever produced,  and likely ever will be produced.  The design is over 25 years old,  and is at the limit of what can be achieved by silicon based technology. 
>> For under $200 you can easily score an HP 3457A which is 6.5-7.5 digits.
