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.
