Front Panel Overview

The 465L front panel provides a number of functions in addition to displaying the
current ozone concentration being measured. Figure 7-1 below shows the display
and keypad portion of the front panel.

7.1.1. Ozone Concentration Display

The 4-character LED display in the center of the front panel normally shows the
current ozone concentration being measured by the M465L.
concentration, one of the unit-of-measure indicators (i.e., PPM, PPB, or UGM)
should be backlit, indicating the current measurement units. If none of these
indicators are backlit, then the display is in Menu mode or Startup mode and is not
displaying the concentration. If the display is in Menu mode, the display can be
returned to Concentration mode by repeatedly pressing the CFG button until one of
the unit-of-measure indicators is lit. Note that even when the display is in Menu
mode, normal measurement and stream selector operation will continue in the
background.

7.1.2. Menu Navigation Keypad

The menu navigation keypad (CFG, ENT and UP/DOWN buttons) is used to
navigate the various menu items available on the 465L. The menus allow the user
to view operational parameters of the instrument as well as view and modify the
configuration of the instrument. See Section 7.2 for more detailed information.
