Press "
" to confirm and exit the setting mode, or you can also save the setting and exit the setting
mode without pressing the button for 30 seconds at any time.
If you need to add or subtract quickly during the setting process, you can press and hold "+" or "-" for
more than 2 seconds for quick adjustment.
Alarm function:
Press "
" to turn on or off the alarm function.
The alarm clock lasts for 1 minute. You can touch " " to enter the snooze function for 5 minutes, or
press any other key to exit the alarm directly.
Maximum and minimum values:
Press "+" to check the maximum
→
minimum
→
return to normal mode for temperature, humidity
and CO2 concentration.
If you press and hold "+" for 2 seconds while viewing the max and min values, you can clear the max
and min values and start recording again.
The maximum and minimum records will be automatically cleared and re-recorded at 0:00 each day.
Manual baseline calibration function:
In normal mode, press and hold "+" for 2 seconds to enter manual baseline calibration preparation
mode. At this time, you can press " " to confirm entry, or press" + "or do not press the button for 30
seconds to exit manual baseline calibration preparation mode.
The operation time of manual baseline calibration mode is 20 minutes. During the operation, you can
press "+" to exit in advance.
Carbon dioxide concentration alarm:
Press "-" to turn on or off the alarm function.
Press and hold "-" for 2 seconds to enter the CO2 concentration alarm setting. The CO2 concentration
value flashes, and press "+" or "-" to adjust.
Press "
" to confirm and exit the setting mode, or you can also save the setting and exit the setting
mode without pressing the button for 30 seconds at any time.
***About manual baseline calibration and automatic baseline calibration of CO2 concentration:
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
baseline calibration can be adopted to correct the drift. During the baseline calibration process, dispose
of 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
baseline calibration algorithm. About 2days after sensor start, will be stored within 2days 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 7days, will be stored within 7days
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
7days.Please ensure that the CO2 concentration is reduced to the outdoor atmospheric level(about
400ppm) within about 2days after the sensor start and for each 7 days of continuous operation.
Automatic baseline calibration function is suitable for office, home and other non-all-weather personnel
