The display will default to showing the amperage being drawn by each phase in the system (all outlets, plus the internal
control system). It will update approximately every 3 seconds, rotating through the three phases one at a time.
The keypad can be used to navigate through power values for volts, amps, watts, voltamps, voltamps reactive, power
factor, and Hertz for each phase, as well as the on/off status of the software controlled outlet relay. (The outlet relay
cannot be controlled from the keypad however.)
