New to this thread? Here's a post index: https://goo.gl/GHyj67Volt nuts, unite!
Inspired by the
overseas DMM calibration club thread, I'd like for us to organize a US-based club.
The most valuable aspect of a reference is its history. As Conrad Hoffman has said, "I'd rather have an ancient reference with a lot of history, than a brand new one with zero history!" [
1]. I'd love to see a few references which develop a thorough history by being shipped to many forum members over the course of years.
I can't claim to bring much to the table myself -- I'm more of an aspiring volt-nut. I have a 4.5, 5.5, ,and 6.5-digit meter (UT61E, HP 3478A, Keithley 196), and a couple of pre-made voltage references (a Geller Labs SVR-T and a PentaRef). Still working on getting all of these devices to datalog to a computer
I'd also like to encourage the creation of
simple hand-made references among the group as well. I've got a handful of LM399's on hand, am in the process of building a small peltier oven to measure tempco's, and have a few of the cheap AD587 boards from ebay on order, just for kicks.
I don't want this club to be exclusionary in any way. If you'd like one of the roving references to pay you a visit and you can post some measurements to this thread, you're in the club.
I'd be happy to maintain a github page or two with all of the csv files of data, etc. I'm a programmer by trade, so I'm happy to help with any sort of python scripting for logging or analyzing data, plotting, etc.
Who's interested?
To get the ball rolling, my current offer is this: If you'd like to take some measurements of my Geller Labs reference, I'll pay for shipping (both ways).
Other members, please feel free to chime in with what you can bring to the club and how you'd like to participate!
