Creative problem solving

You have to applaud the out-of-the-box thinking on this Sherlock Ohms post. Curious to know what replaced the deep fryer once the build process moved to corporate headquarters?

Our laser lab was resplendent with scopes and meters from LeCroy, Agilent, and SRS. Now I know why we always went out for cheese steaks after using the LeCroy. I wonder if LeCroy had a subliminal contract with the anti-cholesterol pharmaceuticals industry...

So you literally burned in your resistors by burning them in? Brilliant. BTW, you're lucky your fried cheese steak dinner didn't kill you before you got to the lab to come up with your gastronomically inspired solution.

We only cook fondue about once every 6 months so I wouldn't consider a contributor in my eventual demise.

Good to hear, Steve. As long as you're not deep frying a turkey, which carries additional risks beyond whatever it takes like.

The process remained the same for the life of the probe.

Alexander, it wasn't really burning in the resistor, but measuring the temperature coefficient. As the circuit warmed, the mismatch between the two resistors changed.

By observing an induced delta, we could select parts that drifted alike.

Thanks for clarifying, Steve.  That's analogous to what vacuum tube vendors used to do, when they sold matched pairs for amp output stages (eg., 12AX7s).

Yes, I agree, Beth. Talk about out-of-the-box think...this is amazing. Great story, Steve.

I believe the same technique was used for resistors in that HP34401 that you were using. It was definitely used in several of the dvms.
