Figure 7-1: Front Panel Display

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 M465M. While displaying concentration, one of the unit-of-measure indicators (i.e., WT%, PPM) 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 operation will continue in the background.

NOTE

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 M465M. 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.
