How do I perform a "Current load test"?

I want to perform a current load test so that I can test my alternator. It
seems to put out enough voltage, but I was cautioned that the alternator
may still not be putting out the necessary amps. Can I perform this test
with my trusty hand held Craftsman multimeter? It was about 30 bucks, and
no where near as fancy as the equipment that they roll out to test my
alternator at Kragen or Autozone. Thank you for any help!
