The correct use of the four-in-one gas detector:

1. Before entering the working zone, safety confirmation must be carried out; after confirming that there is no potential safety hazard, it can enter the working face for detection. When the detector alarms, the working surface should be taken out in time, forced ventilation for more than half an hour, and then tested. The testing personnel must write down the test results of the workplace on the confirmation form and take full responsibility for the accuracy of the test data.

2. After inspection, confirm the turning of the warning plate as required. Warning signs should be hung in a reliable place at the entrance of the workplace. Other personnel are not allowed to turn over the warning signs to avoid being affected by other reasons. Staff who see green noodles are allowed to enter the workplace. The class production supervisor shall supervise and inspect the work of the class inspector to ensure the effective implementation of this regulation.

3. place the probe in the environment to be tested. When the measured gas leaks, the value of the concentration display increases. When the alarm setting value is exceeded, the alarm indicator will light up and an alarm will sound. When the probe moves to the source of the leak, the four-in-one gas detector concentration display shows a value.

4. How to use the four-in-one gas detector? When the battery of the four-in-one gas detector is low, it means that the battery is about to be cut off. Turn off the power in time and use the charger to charge the battery. Charge for 10-14 hours each time!

5. Charging method: plug the power charger into the AC220V power socket, then insert the charging plug into the charging socket of the detector, and then turn on the power switch of the four-in-one gas detector to charge the detector. The green work light is on, the battery light flashes, and the display shows. After charging is complete, turn off the power switch and unplug the charger.

the above is the answer to today's analysis of the correct use of the four-in-one gas detector. it is worth noting that when testing, the testing personnel should keep the number of more than two people, one person should operate, the other person should monitor, keep a certain distance before and after, and single operation is strictly prohibited. The four-in-one gas detector should comply with the detection requirements, do a good job in gas detection, and keep in mind the detection system, detection methods and control standards.
