2.2 Front Panel Display

2.2 Front Panel Display

This section describes the operator interface from the point of view of the front panel. The front panel consists of a 2-line by 40-character alphanumeric display, 8 pushbuttons, and 3 status LED’s. Each of these features is described below.

2.2.1 Front panel display fields

The display is divided into 4 main "fields": the Mode field in the upper left, the Message/Test Function field in the top center, the ozone Concentration field consisting of the most recent instantaneous ozone value field in the upper right, and the Menu field which occupies the entire bottom line of the display. The Menu field is used to define the function of the 8 pushbuttons directly below the display. The buttons are then used for selecting menu items and are also used for entering values such as alarm levels. A typical display is shown in Figure 2.1.
