    If you're eager to explore additional features, press and hold the Y button to enter a password for verification. The initial password is "1234." Use the Y button to navigate through the 4-digit password and the left arrow button to change digits.

    Zero Calibration

    The first function allows you to perform an auto zero calibration on the oxygen sensor. By pressing the Y button, the device will prompt you when calibration is due. To ensure the success of this test, it's important to prepare the unit by placing it in standard calibration gas or clean air for 3 to 5 minutes before the test begins. If "OK" appears upon countdown completion, it signifies the unit is calibrated. You can stop the calibration process by pressing the on/off button or return to the detection interface by long-pressing the Y button.
