Use and maintenance of toxic gas detector:

 1. When the toxic gas detector is not used for a long time, turn off the power of the instrument, store it carefully, and avoid long-term strong direct sunlight or humid environment

 2. The instrument should be maintained regularly, do not drop it, and do not allow the instrument to inhale dust. Failure phenomenon cause analysis and troubleshooting methods Remarks insufficient working time. The charge is insufficient or the battery has reached the end of its life. Check the charging stand so that the contacts of the charging stand are in good contact, or replace the battery. Do not change the type, specifications and parameters of the components in the original circuit during maintenance, and do not change the original package.

All toxic gas detector must be performed on the well by professionals. If the user is unable to repair, he can return to the factory for repair or replacement. The alarm is silent, poor contact, or circuit failure. Check solder joints, wires and circuits. The nixie tube is missing or does not light up. The nixie tube is broken or the welding is loose. Replace the digital tube or repair welding.

 The maintenance specifications for toxic gas detectors have the following points:

 1. Check, calibrate and impact test the detector regularly.

 2. Keep operation records of all inspection, calibration and alarm events.

 3. Keep the surface of the instrument dry and clean, away from moisture, rain and corrosive gases and liquids.

 4. Keep away from dust and keep the surrounding environment clean.

 5. The ambient temperature is moderate, not too high or too low, so as not to affect the electronic components.

 6. Knock, shake or drop the instrument violently, or use it roughly.

 7. Irritating chemicals, detergents or high-concentration cleaning agents are also prohibited. Dip a soft cotton cloth with a little water and lightly wipe the instrument, and it needs to be wiped dry in time.

 8. The detection hole of the instrument should be wiped frequently to keep the pipeline of the hole dredged to avoid liquid flowing into the detection hole. Once the liquid flows into the detection hole, place it down to make the liquid flow out by itself.

 9. For air leakage in the air system, check whether the diaphragm of the suction pump is damaged, and check whether the sealing ring is broken, the condensate gas, and the four-way valve are damaged.

 10. The combustible gas alarm prompts to replace the filter paper, stop the suction pump, and filter the drain in the tank.

 11. Pay attention to the detection interference between various sensors.
