If you don't have a low ohm meter, the next best way to measure its
resistance would be to run a controlled amount of current through it
and measure the resulting voltage drop. Most recent digital
voltmeters can measure DC down in the millivolts and should do just
fine. Some alloys can change resistance dramatically depending on
temperature, so measure accordingly.
