If it's a dynamic mic then the resistance between pins 2 or 3
and pin 1 (= ground) should be 'infinite'. The resistance between
pins 2 and 3 should be low, and you should be able to hear 'clicks'
when measuring it while holding the mic to your ear. It should even
be able to produce some sound when connected to a headphone output,
but be careful when testing that.
