Abstract
Abstract A graphics based display for use with an electronic circuit protection device. Briefly stated, a utility-type electric meter or an electronic circuit protection device includes a liquid crystal device display which allows for the graphical display of information. Upon system start-up or key activation, a menu appears which allows for user selection of the information or parameters to be sampled and displayed.
