How to set zero point for four-in-one gas detector? -Yi Tianyun

As we all know, the 4-in-1 gas detector is a detection instrument specially used for the entrance detection of dangerous environment and confined space at present. Single or multiple gas detectors can be flexibly configured to simultaneously detect combustible gas, O2, CO and H2S. Among them, other gases can be selected for hydrogen sulfide and carbon monoxide according to the requirements of field detection. Its special chip technology greatly improves the response time and stability of gas detection, and greatly improves the service life of the battery. When we use the four-in-one gas detector, it is very necessary to set the zero point, which can reduce the error, accurately detect the gas and obtain the data. Do you know how to set the zero point of the four-in-one gas detector? Let me introduce you to Yi:

Zero setting method of four-in-one gas detector;

1. Press the power button to enter the menu page after booting.

2. Then, press the up and down keys to select the menu item.

3. Select the zero setting, click the power button to enter, select the gas, and check whether the number is 0.

4. If the value is not 0, enter the zero point fine adjustment from the menu, adjust the value to 0 by adding and subtracting items, and save the above to complete the zero point setting, which can be used normally.
