AirSense Model 310en Operator’s Manual
Displays and Indicators
The Model 310en has a single green LED on the front panel
which illuminates whenever the unit is operating. This LED
is on steadily when the measured concentration is below the
high CO
2
limit, and blinks whenever the concentration is
above the limit.
The standard factory high CO
2
limit is 1000 ppm, but can be
adjusted in the field. The procedure for adjusting the high
CO
2
limit is described on page 7.
The display option adds a 4 digit liquid crystal display
(LCD) to the front panel. The display shows the measured
CO2 concentration in parts per million (ppm). 1000 parts
per million equals 0.1%.
