AIC2 Operation Details
Power Up / Operation
On power up the fan will come on, and the display will
indicate “Stabilizing” for about four seconds, at which
point ion measurements will begin. To change the
desired ion polarity, press “Polarity.” Note that when the
polarity is changed, the meter restabilizes.
The 2 million range is the factory default. A display of
1---.-- indicates over range. Pressing “Scale” selects
the alternative 200 million range. The 200 million scale
allows for the measurement of extremely high ion
levels, such as the output of an ion generator.

Averaging
The factory default is 5 second averaging. The
alternative averaging rate is 14 seconds. The 14
second averaging greatly reduces the ion level
fluctuation caused by uneven mixing of ion levels in the
air. However, the longer averaging results in a
corresponding delay in the meter’s response time.
To view the current averaging setting, hold down
“Scale”. Then (while continuing to hold “Scale” down),
depress “Record”. To change the average, follow the
same procedure but hold both “Scale” and “Record”
down for 10 seconds or until alternative average time
appears.
Note that although the display of the average will
disappear five seconds after depressing any other
function, the selected average will continued to be
employed until it is changed.
Since “Scale” was utilized as part of the sequence to
view/change the average, the scale will also change. To
revert back to its original scale, depress “Scale.”
