Description
The Valtronics Model 2011 is a portable Carbon dioxide (CO2) Monitor
designed for use in indoor air quality (IAQ) monitoring.
In addition to CO2, the unit also measures air temperature, dew point, wet
bulb temperature and humidity.
The CO2 Monitor uses non-dispersive infrared (NDIR) technology to insure
outstanding reliability and long term stability.
The unit is powered by four AA batteries or a DC adapter. When the DC
Adapter is used, it cuts off the batteries. The Adapter can not be used as a
battery charger.

Operation
Power ON/OFF
Press the SET button to turn the meter ON or OFF. At power up, the unit emits a short beep and
starts a 30 second count down for warm up, and then enters its normal mode for displaying CO2,
temperature, and humidity readings.
Measurements
The fast response of the meter provides an updated reading every second with the exception of
rapidly changing temperatures which will require a 30 second delay for CO2readings, and as much
as 30 minutes for the humidity to respond.
Data Hold
Pressing the HOLD button will freeze all readings except the STEL and TWA. Pressing the HOLD
button again will cancel the hold mode.
Backlight
Pressing and holding the MODE button for more than 1 second will activate or cancel the Back
Light mode.
STEL, TWA, MIN and MAX
Pressing the M/AV button will display the Minimum, Maximum, and average readings of CO2.
Each press of the button displays MIN, MAX, STEL and TWA in sequence and then returns to
normal operation.
Alarm
The meter has an audible alarm to provide warnings when the CO2concentration exceeds the limit.
It emits an 80 Db warning beep whenever the limit is exceeded. Pressing any button except SET
will stop the alarm, and it will stop on its own when the concentration returns below the set point.

Auto Power Off
The unit will automatically turn off if there has been a 20 minute period of inactivity.
To override this function, press and hold both the SET and HOLD buttons for 2 seconds.
Set-Up
To enter the Set-Up mode from Normal operation, press and hold the SET button for more than 1
second (you should see “AL” in the display window).
CO2Alarm
After entering the Set-Up mode (see previous section), press M/AV to set the CO2 alarm
(note: the CO2 display will be blinking at the current alarm level). Each press of the MODE button
will increase the value by 100 ppm. Pressing the DP/WBT will decrease the alarm value. The
maximum range of the alarm is 100 to 9900 ppm. When the desired value is reached, press M/AV
to save the setting. To return to Normal operation press CAL/Esc.
Temperature Scale
Enter the Set-Up mode, press the Mode button and then the M/AV button. You should see “Unit”
in the display window and “°C” should be flashing. Press the MODE button to change between
“°C” and “°F”. Press the M/AV button to save the setting (note: to return to Normal operation
press CAL/Esc).

Calibration
CO2 Calibration
The meter may be calibrated with either fresh air or with the optional Calibration Kit available
from Valtronics. In most cases, by carefully selecting your calibration site and time, the fresh
air will be sufficient. The calibration site should be selected to be outdoors with fresh air.
Avoid areas with high automobile traffic, crowds of people, and/or ventilating outlets.
Procedure
Place the meter at the chosen site, press SET to turn on the unit and note the CO2 display. If it
indicates 400ppm +/- 25ppm it is not necessary to go any further. The accuracy is ok and it is
not necessary to go through the entire calibration process. If the reading is out of specification,
press and hold both CAL/Esc and MODE to enter the calibration mode. The display will now
show “400 ppm” and “CAL” blinking. When the blinking stops the calibration is complete.
Wait about 10 minutes until the blinking stops and the calibration is completed. The unit will
automatically return to Normal mode. To abort the calibration, turn off the meter at anytime.
Rh Calibration
The Rh feature of the meter must be calibrated with the optional Calibration Kit supplied by
Valtronics. This kit contains 33% and 75% Rh salt solutions and instructions for use.
