SWITCH ON
• When switched on, the LCD full graphical display is
shown for 2 seconds, followed by a “BI”sound, then the
machine get to work, detecting room
temperature, humidity and CO2 value.
With Power Supply:
• Using an adapter higher than 5V 0.5A (package only
with charger cable).
• Plug the charger cable into the DC interface (B6).
• The device enters 60s countdown and then displays
the current value.
• It detects and updates CO2 value every 6 seconds.
With Battery:
• After inserting the batteries, the device enters 30s
countdown and updates CO2 value 5 times.The CO2
value are updated 5 times in every 20 minutes.
• When using the battery alone, press the “DOWN”
button to enter 30s countdown immediately, followed
by re-testing and updating CO2 value 5 times.
Note:
· The countdown process mentioned above is a state
of self-regulation of the CO2 sensor (The original
sensor manufacturer: Sensirion) in order to make the
detection data more accurate.
· The detection port (B3) must never be covered. If the
air circulation is poor, it may result in inaccurate CO2,
temperature and humidity measurements.
· It is recommended to use both batteries and power
supply to avoid losing data in the event of a power
outage.

CO2 VALUE INTRODUCTION
3.1 CO2 Index（A3）
• From 400 to 650 ppm, “ ” lights up dark green.
• From 651 to 900 ppm, “ ” lights up light green.
• From 901 to 1650 ppm, “ ” lights up red.
• From 1651 to 2400 ppm, “ ” lights up dark red.
• Measuring range 400-5000 ppm, below 400 display
400 ppm, above 5000 display 5000 ppm.
3.2 CO2 Concentration Factor Indicator
CO2 ppm
CO2 measured value: carbon dioxide concentration in
ppm (parts per million = 1 millionth = 1 ppm = 10-6
-equivalent to 0.001‰). The Federal Environment
Agency recommends do not stay in an environment
where the CO2 value exceeds 1000 ppm for a long
time.

CO2 ALERT FUNCTION
• Press and hold the “ALERT” button for 3 seconds to
enter the CO2 alert setting and press “UP” and “DOWN”
button to adjust the alert value.
• Press the “ALERT” button to switch on/off the alert
“ ” (A3).
When the alert is not on but the CO2 value has reached
the alert preset value (default 1000 ppm), the icon “ ”
(A2) for ventilation is displayed fixed and the CO2
character (A9) flash.
When the alert is on and the value has reached the
preset value, the alert tone lasts for 1 minute, while the
icon “ ” is displayed fixed and the CO2 character
flash. After one minute the alert is switched off and if
the value still exceeds the preset value, the alert does
not sound again, only the icon “ ” remains fixed and
the CO2 character flashes as a warning.

CALIBRATION
Note:
· When you replace the batteries all the settings will be
lost.
· Always exchange all batteries and only use those listed
in the “Technical Data”.
· Even if the base unit is being powered by the power
source, you should still remove all empty batteries
present from the main unit.
· Make sure that the poles of the batteries are correct
(+/-) when inserting.
· Clean the battery and device contacts if necessary
before inserting.
· Dispose of the old batteries in an environmentally
manner.

“DOWN” buttons at the same time (Don’t let go of your
hand), followed by plugging in the charger or insert
batteries and hold for 3 seconds, then the device enter
calibration mode after the “BI” sound. The CO2 position
displays the “CAL” character and the calibration time is
4 minutes.
• If the calibration is successful, “PASS" is displayed.
After the calibration is completed, please unplug the
charger and remove the battery, and then plug in the
charger or insert the battery again to use the device.
