Abstract
A method for graphically displaying a menu for selection and viewing of the load related parameters of a load connected to an AC load control device, comprising the steps of: (a) monitoring the load related parameters of the load connected to the AC load control device using a voltage shifter coupled to a sensor to bias the voltage above a ground potential by a predetermined voltage to produce a full-wave biased voltage signal; (b) displaying on a graphical display device a menu of a plurality of indicia representing the monitored load related parameters; (c) scrolling through each indicia on said menu; and (d) selecting an item from said menu thereby causing the load related parameters relating to the said indicia to appear on said graphical display device as a signal representation.
