Tracerline® PRO-Chek CO2™ Features
The PRO-Chek CO2 Carbon Dioxide Leak Detector uses an innovative
infrared absorption sensing cell that is extremely sensitive to carbon dioxide
(CO
). However, its circuitry allows the instrument to equalize to the CO2
2
present in the atmosphere, so there is minimal risk of false alarms.
• Specialized infrared cell lasts for approximately 1,000 hours, so you buy
fewer replacement parts
• Infrared cell does not weaken over time, so response remains consistent
and accurate
• Will not react to smoke, humidity, airfl ow or temperature changes
• On-board diagnostics indicate charging status and warn of low battery or
infrared cell failure
• NiMH battery is environmentally friendly, won’t corrode and provides
greater charging capacity.
• Ability to run off 12 volt or AC power adapter/charger
To get the best performance from your PRO-Chek CO2, please read this
manual carefully before you start using your product. If you have any
questions or need additional assistance, please call Tracer Products’
Customer Service Department at 1-800-641-1133 (outside the USA and
Canada, call 1-516-333-1254).

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
DO NOT OPERATE THIS INSTRUMENT IN THE PRESENCE OF
WARNING
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
a natural background concentration of carbon dioxide of approximately
. The atmosphere has
2
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.

Finding Leaks
1. Press the right hand switch until the HIGH sensitivity setting is indicated
by the amber LED
2. Place the tip of the leak-detector probe close to the site of the suspected
leak. Try to position the probe within 1/4 inch of the possible leak
source.
3. Slowly (approximately 1-2 inches [25 to 5 mm] per second) move the
probe past each possible leak point.
NOTE: It is important to move the tip of the probe past the leak to get
a correct reading. The PRO-Chek CO2 only responds to changes in
concentration of the refrigerant from the leak. Moving the probe permits
the instrument to respond properly to these changes.
4. Watch for the yellow lamps to illuminate, and listen for a tone. When the
instrument detects a leak source, its yellow lamps will illuminate and it
will emit a different audible tone.
5. When the PRO-Chek CO2 signals a leak, pull the probe away from the
leak for a moment, then bring it back to pinpoint the location.
6. If the concentration of carbon dioxide is high, press the sensitivity
switch once to change the threshold level to the LOW sensitivity setting
before repositioning the probe at the suspected leak source. The LOW
sensitivity setting helps fi nd the exact site when a leak is large.
7. Once you have isolated the leak source, return the sensitivity setting to
HIGH to continue using the PRO-Chek CO2.
8. When you’ve fi nished leak-testing, turn OFF the instrument.
Recharging the Power Stick
A fully charged power stick should provide power for greater than 6½
hours of continuous operation. To recharge the power stick, use one of the
instrument’s power cords.
NOTE: The PRO-Chek CO2 does not need to be fully charged to operate.
Additionally, the power stick does not need to be fully discharged before
recharging.

DO NOT ATTACH ANY OTHER POWER CORDS TO THE PRO-Chek
CO2’S POWER JACK EXCEPT THE AC POWER ADAPTER AND DC
CORDS DESIGNED FOR THIS INSTRUMENT.
• Connect the AC power adapter cord to the instrument and plug the
adapter into a working outlet, OR
• Connect the cigarette lighter adapter to the PRO-Chek CO2 and tap the
power from your vehicle’s battery.
The battery charging indicator (rear left side) will fl ash when the power stick
is charging, changing to steady illumination when the power stick is fully
charged. Allow 10 hours for a full charge.
WARNING
Changing the Filter Cartridge
The PRO-Chek CO2 uses a specially designed fi lter cartridge that fi ts into a
protective cap. The fi lter cartridge should be changed when it appears dirty
or when substances trapped in the fi lter cartridge seem to be affecting the
sensitivity of the PRO-Chek CO2.
NOTE: Water or oil will not penetrate the fi lter material but will prevent
airfl ow through the fi lter and affect sensitivity.
TURN OFF THE PRO-Chek CO2 AND HOLD THE PROBE WITH THE
FILTER TIP POINTING DOWN WHEN REMOVING THE FILTER CAP.
To change the fi lter cartridge, twist off the protective cap. Remove and
dispose of the used fi lter cartridge. Do not allow any moisture or dust to get
into the probe. Do not disassemble or attempt to clean the material inside
the fi lter cartridge, as it can be damaged when handled. Slide a new fi lter
cartridge into the cap. Twist the cap with the new fi lter cartridge onto the
probe base until it is tight.
NOTE: It is very important that you operate the PRO-Chek CO2 with a
fi lter cartridge installed at all times. Failure to do so could damage the leak
detector’s components.
CAUTION

Changing the Infrared Cell
COMPONENTS MAY BE HOT. TURN OFF DETECTOR AND
DISCONNECT POWER ADAPTER CORD BEFORE REMOVING THE
INFRARED CELL DOOR.
The PRO-Chek CO2’s infrared (IR) cell is located in the body of the
detector. The IR cell is a complete assembly consisting of a metal tube,
connectors and electronic components. The IR cell is not designed to
be taken apart. Doing so will destroy the cell. This specialized IR cell will
operate for about 800 hours.
The PRO-Chek CO2 will fl ash all the leak indicators when the IR cell has
reached the end of its useful life. To replace the IR cell:
1. Locate the latch for the IR cell door on the top cover at the rear of the
detector.
2. Using a small screwdriver, pull the latch forward and remove the door.
3. Pull the IR cell straight out by grasping both edges of the label and
pulling evenly.
4. Remove the replacement IR cell from the protective package.
5. Carefully align the male leads and air tubes on the IR cell with the
connectors mounted on the circuit board. Insert the leads into the
sockets and push the IR cell straight down.
NOTE: Ensure the lead connectors on the IR cell ends are not bent and
the cell is seated tightly.
WARNING

Removing/Replacing the Power Stick
The PRO-Chek CO2 uses a preassembled power stick.
Remove the battery compartment door on the back of the PRO-Chek
CO2 by pressing on both release buttons on the grip and pulling the door
straight out. The power stick is connected to the PCB board via a miniature
electrical connector. Disengage the connector and slide the power stick
out of the PRO-Chek CO2.
To install a fresh power stick, slide the new stick into the PRO-Chek CO2
and push the miniature connector on the power stick into the mating half on
the PCB board.
Once the power stick is in place, close the battery compartment by aligning
the two tabs and sliding the door straight in until it latches. Ensure the wire
leads on the power stick are not pinched in the door. Allow 10 hours to fully
charge the new power stick.
