Great info on a few of those-
"Attach a 1k-100k resistor to ground on the floating pin and repeat the test. "
This is what I was guessing i'd need to do- but just so I understand this correctly- This implys that I cross my signal and ground wires, with a resistor?
Please excuse my noob understanding of electronics- I thought I'd just be hooking a couple wires up to get X voltage- the impedance stuff has me baffled.
