Fascinating DrewE :)
Care to share the Fluke model number and % error + - noted?
I spend an enormous amount of money to maintain my scope in calibration. They do drift and cross correlation of resistance to voltage is one way to detect error.
I see some $5K Fluke instruments out there. Clumsy me - I transport hand-held instruments within sloshy dinghies in a very corrosive atmosphere. Perhaps it's time to obtain a floating airtight case and load it with silica gel packets. I wish cheapskate manufacturers would consider gold plating vulnerable contacts. Computer OEMS do so with card-edge contacts and plugs. If I could keep stuff safe, environmentally, I would consider upgrading my hand held instruments.
Thank you for your reply. It made a considerable impression on me...
