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.

Claims

1. 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.

2. 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 in signal representation and histogram forms simultaneously.
