The four-in-one gas detector can continuously detect four gases at the same time, such as oxygen sulfide, carbon monoxide, oxygen, combustible gas and other gases, and then display the concentration of each gas on the LCD screen. It has important applications in agriculture, chemical industry, construction, electric power, fire protection, natural gas, steel industry, petroleum and petrochemical, sewage treatment and other fields. However, there are many friends who often know little about the specific operation steps after buying a four-in-one gas detector. Do you know the steps to operate 4-in -1 gas detector ? The following is a brief introduction by yi yun Tian:

4-in -1 gas detector operation steps:

Prepare for the 1. check:

1. Check whether the battery power of the four-in-one gas detector is sufficient, and charge it in time if it is not sufficient.

2. Check whether the air filter at the air inlet is blocked by debris. If blocked, clean it up or replace it.

2. the boot operation:

1. press the on/off key and hold it for 5 seconds. the LCD screen displays "ON & quot;, the screen is on, the buzzer sounds 1, and the four-in-one gas detector is turned on.

2. The LCD screen displays the version number and performs warm-up and self-test at the same time.

3, preheating and self-test are completed to the end of the 10-second countdown, the instrument enters the detection mode, and the four-in-one gas detector is confirmed to operate normally.

4. Confirm that fresh air is being pumped and that the oxygen indication is 20.9%.

5. Close the end of the sampling tube to the test point area. After the test value changes stably, read and record.

6. Keep the four-in-one gas detector away from the detection area and place it in the air. After the LCD display value returns to the air state, take it to the detection area for another detection and record the comparison data.

3. the shutdown action:

1. press the on/off key and the LCD will display a 5-second countdown. after the countdown is over, the LCD will display "OFF". then the instrument will not display and the four-in-one gas detector will be turned off.

2. Keep the four-in-one gas detector clean and in a dry, dust-free environment that meets the storage requirements.

To sum up, it is the operation steps of the four-in-one gas detector. By understanding and being familiar with the operation steps of the four-in-one gas detector, we can help us to use the instrument better. Of course, when we use the four-in-one gas detector, we should also strictly follow the instructions, otherwise it may lead to inaccurate measurement results or unnecessary damage.
