SWITCH ON

When switched on, the LCD full graphical display is shown for 2 seconds, followed by a “BI” sound, then the machine gets 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 a 60s countdown and then displays the current value.
• It detects and updates the 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

CO2 Index（A3)

• From 400 to 650 ppm, “ ” lights up dark green.

CO2 Concentration Factor Indicator

Very unhealthy

| ****

Endangering health

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 not staying in an environment where the CO2 value exceeds 1000 ppm for a long time.

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.
• If the calibration fails, “Err” is displayed. After the calibration fails, please re-calibrate.

Calibration Environment

• It should be in an environment with good air flow, such as a ventilated window (CO2 concentration is about 400 to 450 ppm).
• Please ensure that there is no CO2 source in the immediate vicinity.
• Avoid direct sunlight and rain.
• CO2 is detected after calibration. Please try to avoid perfumes, paints, air fresheners, cigarette smoke, alcohol, chemical substances and so on while carrying out measurements since these can lead to incorrect measuring results.

Note:
When you feel that the CO2 value is displayed abnormally, please calibrate the device.
