2.0 Front Panel: Data Entry & Display
The front panel consists of a user interface, which includes an alphanumeric display and a
membrane keypad to select operational modes and alarm settings. The display is a two line,
20 character each, liquid crystal display (LCD). The display is backlit to allow easy viewing over a
wide range of lighting conditions.
The lower line on the LCD is used to signify the function of the “soft keys” marked “A”, “B” and “C”.
The “soft key” current labels are displayed in the lower line of the LCD. If you press these keys, then
