During measurements, if the measurement value exceeds the specified fibrous particle
converted concentration value (refer to Alarm Setting Screen on p. 31), then the backlight of the
touch panel LCD display will illuminate red.
The backlight will remain red after the measurement is finished, but will revert to white after
switching to a different screen, such as the [MENU] screen.
Stopping Measurements

measurement time.
For manual measurements, press the [START/STOP] button to stop the measurement.
When measurements stop, the fibrous particle converted concentration value is displayed.
Touching the [>] button displays the accumulated value. Touching the button again displays the
fibrous particle converted concentration value again.
Touching the [MENU] button displays the main menu again.
If the touch panel LCD is illuminated red, the backlight reverts to white when the main menu is
