I need to hook up a 10k trimmer in the schematic identified by the arrow. There are three terminals on the trimmer and i don't know which one is for what. I've enclosed the data sheet for this trimmer. Question is what are pins 1,2, and 3 for and how would they hook up in the schematic. I'm a new learner so if you could keep it simple for me i'll pick it up faster. Thanks
