The combustible gas alarm detector is a safety instrument that detects and alarms the combustible gas that appears and is used in production. It is an important guarantee to ensure production safety. Installing a gas alarm in a place where flammable gas exists can effectively avoid the hazards caused by gas leakage. Protect the personal safety of staff. When the user purchases a new combustible gas alarm device, needs to do test after the installation to ensure the alarm system can work normally.
The steps to test the combustible gas detector can be used normally are as follows:
1. First, the user needs to read the instruction manual of the combustible gas detector carefully after receiving the goods, and have a general understanding of the basic principle, structure, and wiring method of the combustible gas detector in order to proceed to the next step.
2. When testing the combustible gas detector, the user should test before installing the device, so as to avoid unnecessary effort such as disassembly after the installation is unsuccessful.
3. When testing, connect the combustible gas detector's detector and the combustible gas detector's controller with a corresponding cable according to the instructions.
4. It is necessary to use high-concentration alcohol to test when testing, so that the combustible gas sensor is less harmful. Hold the combustible gas detector in one hand and lift it slightly with the sensor part facing down. Hold the high-concentration liquor in the other hand and gently release some gas under the sensor. If the test is successful, the gas concentration reading on the display of the controller will continue to rise. When it rises to the lower limit alarm value, the alarm controller will emit a high-decibel alarm sound to indicate that there is a flammable gas leak. It is best not to test with a lighter. Because the field testers are not very professional, sometimes the concentration of lighter gas is too high, which will directly cause the sensor to die.
5. After the test is successful, press the "return key" on the controller to cancel the alarm sound. The gas concentration value keeps dropping until it reaches the far point 0%LEL. At this time, the entire test process of the combustible gas detector is completed. After the test is successful, it can be installed and used.
