Precautions and maintenance
1. Please check if the packaging is intact and verify that the product model matches the selected model;
2. Never connect wires while the circuit is live. Power can only be applied after the wiring is completed and checked to ensure that everything is correct.
3. Do not arbitrarily modify the components or wires that have been soldered on at the factory when using the product;
4. Lightning protection measures: The integrated meteorological station system needs to be within the lightning protection range and will also take corresponding measures to protect against the hazards of other induced lightning. During the installation process, attention should be paid to reliable and reasonable grounding to eliminate overvoltage, overcurrent and lightning magnetic pulse outside the equipment.
5. For the wiring of 220V mains power, both electrical safety and the appearance of the building where it is installed must be taken into account.
6. Users should not disassemble the sensor themselves during use, nor should they use sharp objects or corrosive liquids to contact the sensor surface to avoid damaging the product;
7. Regularly monitor and clean the Stevenson screen to check for any foreign objects covering it. Power must be disconnected during cleaning. Pay special attention to cleaning the dust on the panel and the dirt inside the aviation socket.
8. Please keep the calibration certificate and certificate of conformity safe, and return them with the product during repair.
9. During installation, the Stevenson screen must be installed perpendicular to the ground. If it is installed at an angle, rain or snow will enter during rainy or snowy weather, and the moisture will easily affect the data.
