EEG machines measure frequency of neuronal firing in the cortex. The greater the frequency, the more asynchronous the firing and thus the more active the brain. Learning how to read EEG output requires training, but there might be computer programs for that. To use the machine effectively, identify an activity for which you’d like to measure your brain waves, exempli gratia:
Measure degrees of neuronal firing asynchrony during work periods (pomodoros) - useful for calibrating an accurate feeling of focus; measure success of meditation (gamma wave output), as gwern noted; measure which break activities actually induce a relaxed state; and of course check quality of sleep.
