Select the “calibration settings” icon in the main menu interface of 
the detector, click the middle button to enter the password input 

interface (Figure 14), follow the navigation bar prompts to set the 
operation, and enter “1111” to enter the customer calibration 
interface (Figure 15). 

The customer calibration interface includes five functional options: 

zero calibration, zero drift, concentration calibration, one-key zero 

calibration, and factory reset (Figure 15). 

Zero point calibration

: Calibrate the gas zero point. The user 

zero point interface (as shown in Figure 16) will continue to pass in 

gas suitable for zero point calibration for a certain period of time. 

After the value is stable, click the middle button to confirm and 

save. There will be a corresponding prompt on the screen when 

the save succeeds or fails (Figure 17). 

Zero drift

: After the sensor is used for a long time, the zero point is 

offset, and the display is not zero in the clean air, and it can be 

returned to zero through the zero point translation (Figure 18). 

Concentration calibration

: enter the corresponding 

concentration gas, and perform concentration calibration on the 

gas. 

One-key zeroing

: zeroing all the gases in use in the detector. 

Factory reset

: restore all configuration information of the sensor 

module before leaving the factory. 

Note: A series of operations such as zero point calibration have 

been carried out before the detector leaves the factory, and the 

user can directly use it normally. If the user does not operate 

without the manufacturer's guidance, all the consequences shall 

be borne by himself.
