Tracer TP-9361 PRO-Chek CO2 AM08043 - Manual (Page 4)

Getting Started
The PRO-Chek CO2 is shipped with the infrared cell and power stick
installed. The nickel/metal hydride batteries in the power stick are not yet
charged. To charge them, connect the cord of the AC power adapter to
the power jack at the rear of the instrument, and plug the adapter into the
appropriate mains outlet. The battery charging light (rear left side) will fl ash
when the detector is charging, changing to steady illumination when the
power stick is charged. Allow 10 hours for the full charge.
NOTE: You should expect 6½ hours of operation from a fully charged
power stick.
Using Your PRO-Chek CO2
WARNING
DO NOT OPERATE THIS INSTRUMENT IN THE PRESENCE OF
GASOLINE, NATURAL GAS, PROPANE, OR IN OTHER COMBUSTIBLE
ATMOSPHERES.
Using the PRO-Chek CO2 is simple. Press the power switch once to turn
the detector ON. The green ON indicator lamp will illuminate, and the
yellow indicator lamps will illuminate from left to right in a running fashion
while the infrared cell warms up (approximately 60 seconds). When the
detector is warmed up and ready for use, the yellow lamps stop illuminating
and you will hear an audible beeping.
The PRO-Chek CO2 is highly selective for CO
2
. The atmosphere has
a natural background concentration of carbon dioxide of approximately
0.035%. To prevent false alarms, it may be necessary to take steps to limit
changes in this background concentration from sources such as vehicle
exhaust or your own breath.
