Calibration Settings
- Temperature&Humidity&Pressure Calibration
-
Set the calibration value, the device will add calibration value to the current value, then display and report the final value.
- CO2 Calibration
- The device provides multiple calibration methods for CO2 calibration.
Among them, it is necessary to select either manual calibration or Auto
Background calibration to ensure accurate readings.
Calibration Method Description Manual Calibration Put the device in an open outdoor environment for more than 10 minutes and click Calibrate button to adjust the current value as calibration value (400 ppm by default) immediately. This calibration is the fastest but it adapts to the open outdoor environment. This calibration is suitable for some applications which need to place CO2 sensors in unventilated spaces, you can take sensors out to complete the manual calibration before installation.
Restore Factory Calibration Clean the manual calibration and turn back to factory calibration. Auto Background Calibration After enabled, the device will record the offset between 400ppm and lowest CO2 level during a calibration period of 168 hours (7 days) and add this offset to original baseline of sensor to complete the calibration. This calibration is suitable for some applications where CO2 sensors are placed in well ventilated or semi-ventilated areas.
Numerical Calibration Set the calibration value, the device will add calibration value to the current value, then display and report the final value. Barometric Pressure Compensation Enable the barometric pressure to compensate the value. This requires to enable the barometric pressure sensor.
