Using these IC test hooks is a breeze. First, identify the small points on the IC, like the legs of a SOIC IC. Then, use the two hooks to grab those points. If you're using them with a Bus Pirate logic analyzer harness, just connect the male pin to the appropriate part of the harness. You can also insert the male pin directly into a breadboard or other standard 0.1 - inch connectors. When handling the hooks, be gentle to avoid bending the hooks. Keep them in a dry place to prevent rust. After use, you can put them back in the bag provided to keep them organized and protected.
