AIR SAMPLING
Once connected to the power, the AR112C starts to initiate. The
whole column on the far right of the bar graph will light up for
approximately 10 minutes.
Then the unit will sample and display air quality according to the
set interval and sensitivity. A normal dynamic display consists of
seven columns of the bar graph lighting up one after another. Then
the display will freeze for a few seconds and start again. The current
temperature and humidity will be displayed at all times.

When operated solely on batteries, the unit will not be able to
sample air quality. Only the temperature and humidity will be shown
and the botton row bar graph will flash.
HOW TO READ AIR QUALITY
The air quality is displayed on the bar graph and rated very good,
good or bad. An indicator will light up to show what the air quality
is.
Very Good
You can select to display the average air quality in three intervals:
70 seconds, 7 hours or 7 days. To do so, press MODE repeatedly.
When the 7-hour or 7-day interval is selected, the 0 column means
the current hour or day and each column to its left means a previous
hour or day, respectively. When the 70-second interval is selected,
the current 10 seconds are on the column on the far right. Each
column to its left means 10 previous seconds.
HOW TO ADJUST SENSITIVITY LEVEL
The sensitivity level affects how the unit rates the air quality. You
may have to adjust the sensitivity according to the actual
environment of the installation or specific needs.
