After a period of use, the Portable H2s Gas Detector will have zero point drift. In an environment without harmful gases, the displayed value is not 0 (oxygen 20.9). At this time, the instrument can be zero-point calibrated. The operation is as follows: hold down the left button and press the right button at the same time to enter the system menu, select system settings, and enter device calibration. After entering the six ones of the password, select zero point calibration (Oxygen selection gas calibration), and press the OK key to complete the setting.
