I want to record the resistance of a pot which is attached to the shaft of a gearmotor that rotates 360 degrees in ~4 minutes. I would like to make recordings each second. I will use a Labjack U12. I would like any reference to how to configure the Labjack and software.

A potentiometer is basically a voltage divider circuit. In Section 2.1 of the U12 User's Guide, start reading about that right after Figure 2-3:
