Thermocouple Plug

Have some thermocouple wire but no plug?

This thermocouple plug allows you to make a half decent replacement for the parts you buy. It does not have a wider negative leg so if the reading goes down when you warm the end up, switch the plug around.

This plug makes use of a standard car blade ["Mini Fuse"](https://en.wikipedia.org/wiki/Fuse_(automotive)) which has slightly short legs but otherwise fits perfectly in my TC meter, in fact the fuse's blade thickness is more than the plugs the meter came with so it fits more snugly.

Mini fuses cost between 5c and 50c from online suppliers if you buy quantities of 50 or more. For one fuse from your car parts supplier you'll be paying about $1.00 each for a pack of 5 or 10. You might just want to buy a complete thermocouple wire with a plug online or $4 or $5 each (set of 4 or 5 for $20)

First trick is to blow the fuse, I just picked the little bridge out with a piece of wire so that the two legs are no longer shorted out.
