Introduction
Congratulations on your purchase of the Extech C010 Carbon Monoxide Meter. The CO10
measures and displays CO concentrations between 0 and 1000 parts per million (ppm).
Safety Information
Carbon monoxide is life threatening even at relatively low concentrations; learn
and recognize the effects of CO poisoning (see Table below). Do not use this
meter as a personal safety monitoring device.
Effects of CO poisoning
0-1 PPM Normal background levels
9 PPM Maximum indoor air quality level
50 PPM Maximum 8 hour average exposure level
200 PPM Mild headache, fatigue, nausea and dizziness
400 PPM Frontal headache, life threatening after 3 hours
800 PPM Dizziness, nausea, convulsions, DEATH WITHIN 2 TO 3 HOURS
1600 PPM Nausea within 20 minutes, DEATH WITHIN 1 HOUR
12800 PPM DEATH WITHIN 2 TO 3 MINUTES
Ensure that the meter is turned on in an area free of
CO. If not, the meter will read incorrectly when
subsequently measuring CO.

Operation
MEASUREMENTS
IMPORTANT: Ensure that the meter is turned on in an area free of CO. If not, the meter will
read incorrectly when subsequently measuring CO.
1. Press the ON/OFF button to turn the meter on.
Allow time for the meter to perform the self test and for the display to
settle.
2. To use the meter, trace the CO10 around the area of the suspected
leak.
3. The meter will indicate the presence of CO (in ppm) on the LCD display. An audible beep will
sound at 35 ppm alerting the user that the threshold of dangerous CO levels has been
detected. The higher the concentration of CO, the faster the beeper will sound. Above 200PPM
the beeper will sound continuously.
4. To turn the meter off, press the ON/OFF key. If the meter is left on, the meter will automatically
power off after 15 minutes.
MODE Button Functions
Press the MODE button to step through the following functions..
1. Maximum Data Mode: Displays the highest reading taken. This reading
is cleared when the meter is powered off.
2. Recall Data Mode: Press the SEL button to step through and recall the
data from the 10 memory locations. The current memory location (0-9)
is displayed in the top right.
3. Store Data Mode: In this mode, you can store the reading to the next
available memory location by pressing the SEL button. “REC” is
displayed in the top right.
4. Recall Alarm Mode: The meter will display the alarm level data setting
