Keithley 2010 Preliminary Porn

dr.diesel:
I hold Keithley's low measurement handbook and robrenz directly responsible for this purchase!   :-+

In reality I simply needed another eye on the bench and thought I'd improve my resolution, with DCV and resistance measurements being the focus.

For whatever reason the 2010 is not particularly popular, but it does offer 7-1/2 digits and offset compensation to help reduce thermal EMFs.  A few highlights:









A few internal picts, I can't get the aluminum cover off without pulling the entire board.  My new capacitors haven't arrived yet, but once they do I'll pull the board and take further picts.  The voltage reference appears to be the SL40057 from LT, which I can't find any info on?  It's a 4-pin device which would lead me to a LM399, however I didn't think it was quite up to the task of this resolution.  Note the temperature of the -15v reg in the second pict, a bit high for my comfort level.













The 2010 is a single board, shares the same high speed, low noise A/D converter technology as the Models 2000, 2001, and 2002 according to their website.  This one was manufactured in late 99 with the last and only cal being 2/25/2000.  The power supply caps appear fine, but I'm planning to replacement them, then ship it off to Keithley for a firmware update and full cal.

Thanks for opening her up, the vref could be a selected low noise sample of the lm399. Does it say anything on the side of the package?

Not too much on the side, Philippines E94022.

Thanks, Doc.

I am sorry for being a bad influence :'(  You may want to make a box connector like towards the end of this video but without the switching for connecting your Kelvin clips to your beautifull new Keithley ;D
