I am taking a few measurements of an LTZ1000A voltage reference to turn them into statistics. Then I am taking apart the Solartron Schlumberger 7081 bench top voltmeter to find opportunities for improvement. I am CNC machining a new front panel segment to fit Pomona 3770 low thermal EMF binding posts. Finally I am installing an ultra-precision LTZ1000A voltage reference, but the new components have to settle down before we can see any results.
