Introduction

Congratulations on your purchase of the Model CO210 Carbon Dioxide Monitor and Datalogger.

The CO210 measures, displays, and logs CO2level, air temperature, relative humidity, date, and

time. The included Windows-based software and USB cable allow you to set up the datalogger

and transfer logged data to your PC. The CO210 is an ideal instrument for indoor air quality (IAQ)

monitoring. The CO210 is shipped fully tested and calibrated and, with proper use, will provide

years of reliable service.

Operation

Powering the CO210

Plug the supplied power adaptor (5V/0.5A) into the power jack on the back of the meter

and to an AC power source, the meter will switch ON. The front panel LED power

indicator will light, and the beeper will sound. If the power source voltage is incorrect,

‘bAt’will display, and the LED indicator will flash. Do not use the CO210 with an incorrect

power source.

In normal operation the LCD will display CO

, temperature, humidity, date, and time. The air

quality level is also displayed (GOOD, NORMAL, or POOR).

Measurements

The CO210 starts measuring as soon as it is powered and updates readings once per second. If

the operating environment changes (from high to low temperature, for example), it will require

2 minutes for the CO2 sensor to respond and 10 minutes for the humidity sensor to respond. Do

not hold the meter close to your mouth or any other source of CO2.

MIN/MAX Mode

In the normal mode, press the MIN/MAX button to see the minimum or the maximum CO2,

Temperature, and Humidity values. Each press of the MIN/MAX button steps through the MIN,

the MAX, and then the normal display mode. Long press the RESET button to clear the minimum

and maximum values from memory.

Data Logging

The CO210 logs CO

, air temperature, and relative humidity readings (along with date and

time). The memory capacity is 15999 points (5,333 CO

, temperature, and humidity

records). The sample rate is adjustable (in the setup mode) from 1 second to 4 hours, 59

minutes, 59 seconds.

After setting the sampling rate, long press the LOG button to start logging. The green

LED blinks while logging and the main display digits alternate between real time CO

readings and the abbreviation ‘rEC’(record). The lower displays show the real time

temperature, humidity, date, and time.

To stop logging, long press the

ESC

button

. The LED stops blinking, and the main display

will alternate between real time CO

readings and the word ‘End’. Long press the ESC

button again to return to the normal operating mode. See the PC Datalogger Software

section, next, for details on downloading logged readings to a PC.

Note that the MIN/MAX memory is still operational during data logging and is cleared

each time a logging session is started.

PC Datalogger Software

The supplied Windows-based PC software and USB cable allow you to set-up the datalogger,

download logged data, and view the logged data graphically or in text format on a PC. The

software and USB driver is also available from the Extech website.

Connect the CO210 to a PC using the supplied USB cable. The USB port is located on the back of

the CO210. Install the software, open it, and refer to the program HELP utility for complete

operational information. Contact Extech support if you have questions or problems.

Alarm Function

The CO210 features an audible (beeper) and visual (flashing fan icon) alarm that warn when the

CO2concentration exceeds the programmed threshold. There are two alarm thresholds, the

‘POOR’air quality threshold (that triggers the alarm), and the ‘NORMAL’air quality threshold

(that cancels the alarm). See the Setup mode to set these threshold settings.

The audible alarm can be manually silenced by pressing any key, or it will automatically stop

when the CO2reading is no longer in the alarm region (the user can subsequently press and hold

the RESET button to re-activate the alarm, if desired).

If the beeper is manually silenced, it will sound again when readings

move out of, and then back into, the alarm region.

The fan icon continues to flash even when the beeper is manually

silenced. It disappears only when readings are no longer in the alarm

region.

Setup Mode

Long press the SET button to enter the setup mode.

P1.1: Threshold setting for the ‘GOOD’air quality display icon

When entering the setup mode, P1.0and ‘CO2’are displayed. Press the SET button again to

access P1.1for setting the CO2upper limit (threshold) for the ‘GOOD’air quality display icon. The

current set value will appear blinking on the display.

Press the ▲or ▼button to increase or decrease the value. Each press adjusts in 100 ppm

increments. The range is 0 to 700 ppm (default is 700 ppm).

When the value has been set, press the SET button to confirm the ‘GOOD’threshold and move

to P1.2for setting the ‘NORMAL’display threshold. Press the ESC button to exit without saving.

P1.2: Threshold setting for the ‘NORMAL’air quality icon and the CO2Alarm

P1.2is used for setting the CO2high threshold for the ‘NORMAL’air quality display icon. It is also

the low threshold for the alarm beeper and the flashing fan alarm icon. The current set value

will appear blinking on the display.

Press the ▲or ▼button to increase or decrease the value. Each press adjusts in 100 ppm

increments. The range is 700 to 1000 ppm (default is 1000 ppm).

When the value has been set, press the SET button to confirm the ‘NORMAL’limit and move to

P1.3for setting the ‘POOR’display threshold. Press the ESC button to exit without saving.

P1.3: Threshold setting for the ‘POOR’air quality icon and CO2Alarm

P1.3is used for setting the high CO2threshold for the ‘POOR’air quality display icon, alarm

beeper, and flashing fan icon. The current set value will appear blinking on the display.

Press the ▲or ▼button to increase or decrease the threshold. Each press adjusts in 100 ppm

increments. The range is 1000 to 5000 ppm (default is 1000 ppm).

When the value has been set, press the SET button to confirm and move to P1.4. Press SET again

to continue.Press ESC to exit without saving.

Caution: Set the alarm value within the specified range of the CO210 where accuracy is

assured. Out of specification readings are for reference only.

P5.0 Data Logger Sampling Rate

Press the ▲button in P1.0 three times to access P5.0 to set the data logger sample rate. The

available range is 1 second to 4 hours, 59 minutes, 59 seconds.

Press the SET button to access P5.1, the HOUR digits will blink. To change the hour, press the ▲

or ▼button. Press the SET button to save the setting and then repeat this procedure for P5.2

MINUTES and P5.3 SECONDS (the SECONDS value is shown in the center display area). Press the

ESCbutton return to P5.0 without saving the setting.

Calibration

The meter is calibrated to a 400ppm CO2concentration at the factory. If the accuracy becomes a

concern, or after one year of use, return the meter to Extech for calibration or continue below.

ABC (Automatic Baseline CO2Calibration)

ABC (Automatic Baseline Calibration) establishes a baseline calibration to eliminate the zero drift

of the infrared sensor. The ABC function is always “ON” when the meter is powered.

ABC is designed to calibrate the meter at the minimum CO2reading detected over 7.5 days of

continuous monitoring (power on). It assumes that the area being tested receives fresh air with

a CO2level of approximately 400ppm at some point during the monitoring period. Note that It is

not suitable to use the CO210 in closed areas with consistently high CO2levels 24 hours a day.

Manual CO2Calibration

Manual calibration is suggested to be done outdoors on a clear day with good ventilation and

fresh air where the CO2level is approximately 400 ppm. Do not calibrate on a rainy day because

high humidity will affect the CO2level in air.

CAUTION: Do not calibrate the meter in an atmosphere of unknown CO2concentration. Do not

calibrate in places crowded with people, pets, plants, or where high CO2concentrations may

exist such as near ventilation ducts or fireplaces.

Place the meter in the calibration area and switch it on. Press and hold

the SET, ▲,and ▼buttons simultaneously for > 1 second to enter CO2

calibration mode. “400ppm”and “CO2” will blink while the calibration is

in process.

The calibration will require approximately five (5) minutes. When the calibration is complete, the

blinking stops and the meter returns to the normal operating mode. Press ESC to abort a

calibration session (not recommended).
