Used NTK. any tests to run to be safe?

[krinjah]

hey Guys and Girls.

I just bought a Rode NTK mic, and have it for one night to test before the deal is final.

I listened to it, and heard some noise during preview in my headphones.

It's very possible the noise is just electrical interference from the other stuff in the room etc etc, however:

without an ohm meter or other electronic equipment, is there any test I could / should do on the mic tonight, aside from listening / recording through it, to determine if it's in good shape?

Anyway to test the electronics?

Thanks so much gearslutz!
