4 in 1 gas detector use maintenance must know what? The four-in-one gas detector integrates the detection functions of four gases, which can be said to be one of the most economical and efficient gas detectors. To use such a sharp instrument well, we must know the following detection common sense.

Four in one gas detector necessary knowledge:

1. How is the four-in-one gas detector dark and quiet?

Generally speaking, if the four-in-one gas detector is placed for a long time, it needs to be fully charged before use. When it is turned on, the screen display and sound are normal.

If necessary, the four-in-one gas detector needs to be calibrated and maintained after use in particularly harsh environments.

2. How is the four-in-one gas detector connected to the alarm device?

When some of the detected gas concentration is too high, especially flammable gas, toxic gas concentration is high, the need to alert the user to prevent accidents.

Generally, the four-in-one gas detector has the function of setting the warning value of gas concentration. When the gas concentration is too high, the buzzer of the four-in-one gas detector will sound an alarm. The four-in-one gas detector can also communicate with some peripheral devices for alarm value connection and transmission.

3. How to set the zero point of the four-in-one gas detector?

First, after starting up, press the power button to enter the menu page; Next, press up and down to select menu items; Select the zero setting, click the power button to enter, select the gas, and check whether the number is 0. Finally, if the value is not 0, enter the zero fine-tuning from the menu, adjust the value to 0 by adding and subtracting, save the above to complete the zero setting, and it can be used normally.

Matters needing attention for maintenance of four-in-one gas detector:

1. It is forbidden to immerse the four-in-one gas detector in liquid.

2. Maintenance requires professional and qualified personnel to operate. Before operation, all contents of the user manual must be fully understood for safe operation.

3. Try to check the four-in-one gas detector every day after work, and record the results of each inspection, so as to find and solve problems in time.

4. Maintain all maintenance. Wipe the instrument case with a soft cloth. Do not use solvents, soaps, polishes or other corrosive chemicals to clean.

5. If the four-in-one gas detector is in combustible gas or specific environment for a long time, it should be calibrated every day and replaced if necessary.
