User's Guide Carbon Monoxide Meter Model CO10 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. Meter Description 1. LCD display 2. Power ON/OFF key 3. MODE key 4. Power on/Alarm light 5. SEL key 6. Sensor 7.

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.. REC 1.
