Hello, I opened a keithley 2015, it contains a voltage reference
that resembles an LMx99, but is marked Linear Technology
and reports thes codes SL40057 IC-527 0430 the last seem a datecode.
here a pic:
I measured +6,99... volts on the pin 1 vs pin 2.

Anyone has more info?

Does the 2001/2002 use the same reference?

Also I was warned to change the psu electrolytics, seem they
are prone to failure.
