Gas Detector

PCE-CMM 10

I. Introduc�on

CO2 is a naturally occurring gas that emied at great levels by human acty and it is one of

several greenhouse gases in our atmosphere. CO2 only accounts for 0.03% of the fresh air. If you

breathe high concentraon CO2, you may be at risk of carbon dioxide intoxicaon. Symptoms of

carbon dioxide toxicity include headache, irregular heartbeat, nausea, unconsciousness, or even

death.

PCE-CMM 10 is a CO2 meter that measures CO2 concentraon, temperature and humidity. This

meter is widely used in homes, shopping malls, oces, vehicles, staons etc.

Please read carefully and follow all warnings and precauons before using the device.

II. Open box inspec�on

Open the box and take out the device. Please check whether the followingitems are decient or

damaged and contact your supplier immediately if they are.

2. Operations

CO2 measurement

Long press to turn on the meter. It takes 120s to stabilize CO2 concentration. CO2

concentration, ambient temperature, relative humidity will be displayed on the screen. CO2

concentration value is refreshed every 3 seconds.

Note: if CO2>1000ppm, buzzer goes off with red backlight flashing. The audio alarm’s default

setting is OFF, long press to turn on the audio alarm.

STEL

Short-term exposure limit

TWA: The average exposure within the workplace to any hazardous contaminant or agent using

the baseline of an 8 hour day or 40 hours week work schedule.

STEL: The acceptable exposure limit to a toxic or irritant substance over a short period of time

(time-weighted average), usually 15 minutes.

Auto shutdown

The meter will automatically shut down if there is no operation for 2 hours.

Battery

Charge the battery when is displayed on the screen. It takes 2~3 hours to fully charge the

battery.

3. Calibration

Date/time

Please refer to Operation Instructions-Functional Buttons to calibrate date/time.

CO2

Note: CO2 function has been calibrated before delivery. If the value is greatly deviated from the

standard, you can calibrate it by either methods below:

①Automatic calibration

PCE-CMM 10 has the built-in self-correcting ABC (Automatic Baseline Correction) algorithm to

automatically adjust the base value.

1) Turn on the meter and leave PCE-CMM 10 at a place where there is flowing fresh air for 3 days

(powered by the adaptor)

2) ABC function will automatically adjust and correct the CO2 standard value.

Warnings: ABC function is always on, do not use this meter in closed environment where CO2

concentration remains relatively high.

②Manual calibration

1) Turn on the meter, leave it outdoor for 20 minutes

2) Long press MODE+ until appears on the screen. Calibration takes 10 minutes.

symbol disappears when calibration is done.

Note: It is suggested to calibrate the meter in outdoor environments where there is air flow. Keep

device away from animals, plants and human.
