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. While displaying
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.
