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.

CO10 V1.1 05/03

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.
