CO2 concentration and CO2 trend display

• CO2 concentration is displayed by an 8 grid bar graph, who change accordingly to the measured CO2 value:

• According to the change of carbon dioxide concentration, if it rises within one hour or more than or equal to 100 ppm, the arrow points up; if it drops within one hour or more than or equal to 100 ppm, the arrow points down; if it does not exceed 100 ppm within one hour, the arrow points flat.

• Carbon dioxide concentration detection frequency is 5 seconds.

• According to the current CO2 concentration value, there are four levels of CO2 appraisal:

EN6

EXCELLENT: 400 600 ppm;

GOOD: 601 ~ 1000 ppm;

MEDIUM: 1001 1500 ppm;

POOR: 1501~2000 ppm;

POOR is flashing: 2001 ppm and above

CO2 concentration in 24 hour history display

• CO2 concentration history is displayed by an 8 grid bar graph, who changes accordingly to the measured CO2 value:

8 Grid: 3501 ~ 5000 ppm
7 Grid: 2001 ~ 3500 ppm
6 Grid: 1501 ~ 2000 ppm
5 Grid: 1001-1500 ppm
4 Grid: 801 1000 ppm
3 Grid: 601 ~ 800 ppm
2 Grid: 501 600 ppm
1 Grid: 400 500 ppm

• The average CO2 concentration over 24 hours will be briefly shown in a bar chart: -24h, -18h, -12h, -9h, -6h, -3h, -0h.

Calibration of CO2:

EN7

The sensor has an automatic calibration and can therefore be used immediately. This usage variant is recommended. A manual calibration is also possible.

Manual calibration function:

• In normal display mode, press and hold the "+" button for 2 seconds to enter manual calibration mode. At this time, you can press "to confirm entry, or press" + "or do not press the button for 30 seconds to exit manual calibration mode.

• Press and hold "--" for 2 seconds to enter the CO2 concentration alarm setting. The CO2 concentration value flashes. Press the "+" or the "-" button to adjust.
• Press " " to confirm and exit the setting mode, or you can also save the setting and exit the setting mode without pressing any button for 30 seconds at any time.

Notes:

• Due to transportation, vibration, aging and other reasons, the carbon dioxide sensor may cause the zero drift and the detection accuracy is reduced. In order to restore the accuracy of the sensor, manual calibration can be adopted to correct the drift. During the calibration process, place the product in an environment with an outdoor atmospheric CO2 concentration level (about 400ppm) to ensure that the CO2 concentration in the environment is stable.

• Due to transportation, vibration, aging and other reasons, the carbon dioxide sensor may cause zero drift and reduce the detection accuracy, so the sensor will correct the drift through the built-in automatic calibration algorithm. About 48 hours after sensor start, will be stored within 48 hours minimum carbon dioxide concentration values, to amend the basic value of the atmospheric environment outdoor carbon dioxide concentration (about 400ppm ), since the time of about 7 days, will be stored within 7 days of the lowest carbon dioxide concentration values, to amend the basic value of the atmospheric environment outdoor carbon dioxide concentration (about 400ppm ). The cycle was then repeated for 7 days. Please ensure that the CO2 concentration is reduced to the outdoor atmospheric level (about 400ppm ) within about 48 hours after the

sensor start and for each 7 days of continuous operation.

• Push the power switch to ON and connect the product with the USB-Adapter to a power source. This will be regarded as the sensor start. If the symbol of low power appears when the lithium battery is used for power supply, then it will be regarded as the sensor start after the DC is re-inserted for power supply.
• Automatic calibration function is suitable for people who are active in office, at home or do other non-all-weather activities and people who enjoy a good ventilated environment. It is not applicable to agricultural greenhouses, farms, warehouses and other places.
• During carbon dioxide detection, avoid product vibration and direct blowing on the sensor by strong winds, which may cause deviation of the carbon dioxide detection value.

Backlight brightness levels:

• Touch " " to switch backlight level, a total of four levels (high - medium - low - off).

Low power indicator:

• The low power indicator " " will be displayed, when the monitor has low battery power
