Super easy. Take a look below,
For transistors, you only need to test base to ground, collector to ground, and emitter to ground. So negative lead on ground, positive lead to each leg.
Or for IC's, you're going to do the same basic thing, but instead of each transistor leg you test each IC leg. So you'll put the negative lead on ground, positive lead to each leg. Make sure you check the pinout for the IC so you can label each leg correctly.
