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.
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.
NOTE
Even when the display is in Menu mode, normal measurement
and stream selector operation will continue in the background.
