The four-in-one gas detector is the 1 single gas or multiple gas detectors that can be flexibly configured. It can flexibly configure single gas or multiple gas detectors and simultaneously detect the following four gases: Combustible gas, O2 , CO and H2S. But no matter what kind of instrument product, we need to set the zero point before using it.

because 4-in -1 gas detector the phenomenon of zero drift, migration, the range becomes larger or smaller, affecting the measurement accuracy. By setting the zero point, the error can be effectively reduced, so as to accurately detect the gas and obtain the data.So do you know what is the method of setting the zero point of the four-in-one gas detector? The following Yi Yuntian Xiaobian for you to introduce:

the method of setting zero point of four-in-one gas detector:

1. Press the power key to enter the menu page after power on.

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

3. Select the zero point setting, click the power key to enter, select 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 through the add and subtract items, and save the above to complete the zero point setting, which can be used normally.

In summary, it is the method of setting the zero point of the four-in-one gas detector. The inspection and adjustment of the zero point is a skill that the instrument worker must master. Through the zero point setting, the accuracy of the measurement data of the four-in-one gas detector can be guaranteed, so that the measured data will be more accurate and the error will be small.
