Teach you how to use the portable gas detector correctly
The operation of the gas detector is quite intelligent, just like a mobile phone, many people can use it at hand, but the instrument is not a mobile phone, its core function is to detect qualified data, the rigor of the inspection work does not allow us to use it without mastering the operation method The safety protection of the instrument is very important for this kind of composite gas detector, especially the four-in-one gas detector. The accuracy of the data of the detector is directly related to the health and safety of the people. Next, the editor of Instrument Equipment Network Teach you how to get started quickly
1. Before entering the working section, a safety check must be carried out. After doing the corresponding safety precautions, such as masks, gas masks, etc. (see the actual situation of use), check to ensure the safety of the test engineer and avoid safety risks , you can enter the excavation working face inspection.
When the four-in-one gas detection instrument alarms, the excavation face should be withdrawn immediately, and the recorded inspection statistics should be stored. After about half an hour of forced ventilation, two measurements and inspections should be carried out.
The inspection personnel must write the inspection results of the workplace on the confirmation form, and take full responsibility for the accuracy of the inspection statistics.
2. After the inspection, check the rotating warning sign according to the regulations.
The warning sign should be suspended at a fixed place at the entrance of the work site, and other workers should not roll the warning sign, and at the same time avoid being affected by other reasons; workers are not allowed to enter the work site until they see the environmental protection side.
The on-duty production manager supervises and manages the work of the on-duty inspection personnel to ensure the effective implementation of this requirement.
3. Place the camera of the handheld oxygen detector in the natural environment to be tested. When the measured gas leaks, the scale value of the concentration value display information will increase. When the alarm preset value is exceeded, the alarm display light will be on, and the ticking sound .
When the camera moves to the source of the leak, the value displayed on the oxygen detector concentration display becomes larger, and the reading is recorded.
4. When the battery capacity of the handheld oxygen detector is low, it means that the rechargeable battery is almost out of power. You should turn off the machine immediately and use the charging head to charge the battery. Each time the battery is charged, it takes 10-14 hours!
5. Battery charging method: Insert the switching power supply charging head into the AC220V power plug, then insert the charging plug into the battery charging jack of the detector, and then turn on the main power switch of the four-in-one oxygen detector to charge the detector battery. Charging, the environmental protection work light is on, the rechargeable battery light is flickering, and the display shows the message '----', after the battery is charged, turn off the main power switch, and pull out the charging head
