So many ways to go with that.Ah, the good old days. Used to run the upstream development lab, every instrument had to be certified to NIST standards.
Get a timer recalibrated and certified, 100 bucks. New timer, with certificate, 15 bucks. Same with lots of other items. They all got "scrapped"
I guarantee they are not in use for QA purposes.
Admitted my scopes aren't calibrated and i have to do that manually.
I did deliver an application for Rocket Center WV to test and calibrate torque devices ranging from torque watch gages to 2000 ft-lbs wrenches. At the low end a paper cup on a 6" leaver arm, at the other end a 5' torque wrench with a 5' extender was used.
In the case of the the former the metrology lab lead pointed out fluctuations at the low end (inch-ounces). I blew on the paper cup and the reading went crazy. He replied "I wll have to cme in on Saturday when there aren't fork trucks running around."
In the case of the the latter I watched as they set up the cheater bar and 3 people leaned into the wrench... as I hid behind an i-beam incase something went wrong.
Bringing it back on topic...
The lead meteorology lab lead had been calibrating torque wrenches for decades. His name was Dale Evans. During development i used a collection of torque wrenches i owned including some dumpster finds. I was impressed when Dale tried out all if my torque wrenches and screw drivers some of which came from dumpsters using just his hands...
