Carbon Monoxide Meter
Model CO10
Introduction
Congratulations on your purchase of the Extech C010 Carbon Monoxide Meter. The
CO10 detects the presence of carbon monoxide (CO) and measures and displays
concentrations between 0 and 1000 parts per million (ppm). Careful use of this meter will
provide years of reliable service.

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
35 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

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.
Press the ON/OFF key once to turn the meter on. The meter will perform a short self-test.
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 to conserve battery life.
To use the meter, trace the CO10 around the area of the suspected leak.
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.
HOLD
Press the HOLD button to freeze the reading in the display. The hold icon will appear in the
display. Press the HOLD button again to return to normal operation.
MAX
Press the MAX button to hold the highest reading. The MAX icon will appear in the display.
When in max mode the meter only displays the highest CO level it has detected. Press the
MAX button again to return to normal operation.
BACKLIGHT
Press the backlight key to turn the display backlight on. Press the backlight button to turn
the backlight off.
