Grounding the AIC3Pro
Air Ions are charged air molecules. These air molecules are measured with respect to earth/ground
reference. Thus, the meter must have an earth ground reference either via the hand/body of the
operator or a ground cable connected to an outlet ground or other ground connection.
At low air ion counts (<20K ions/cc), holding the meter (with the kickstand removed) maintains suffi-
cient ground reference, provided that your body doesn't build up a static charge. Occasionally touching
a pipe or the screw on a light switch plate will ensure accurate readings.
When using the kickstand (no meter to hand contact) or any time when high ion counts are possible,
such as the ion counts near ionizers, the ground cable must be used!
Common Symptom if the Meter Is Not Grounded:
If not grounded when exposed to high ion levels, the
meter will initially show a high ion count. Then as the
meter's housing builds up a static charge from the
charged air molecules, air ions in the vicinity of the
meter will be repelled, and the air ion count will rapidly
decrease to near zero. Materials between the ion
counter and ion source can also become charged and
repel air ions. See the bottom of page 15.
Bi-Polar Ionizers:
Well balanced bi-polar ionizers minimize the static
charge compared to single polarity ionizers. However,
any static electricity (even that which is created from
walking on a carpet) will influence air ion readings.
Grounding insures accurate readings.
A 10 ft. (3 meter) ground cable is included with connectors
for grounding (earthing) the AIC3Pro to a standard wall outlet
(mains), ESD mats, metal water pipes, or metal heating/air
conditioning ducts.
Using USB Connection as Earth Ground:
The included USB charger will not provide earth
grounding. PCs and laptops with the third prong
ground connection power cords usually provide
earth ground via their USB ports. Unless you know
for sure that your PC's USB ports are grounded, do
not rely on grounding via a USB cable.
USB Connecting Caution
When measuring high ion counts near an ion
generator, make sure the meter is grounded prior
to connecting the USB cable to a desktop or laptop
PC. Failing to do so may damage the AIC3Pro
and/or the computer!
