6、note
1. When the transmitter is connected to the controller, it is recommended to use 18-24AWG shielded cables to prevent noise interference;
2. Before connecting the power supply, it is necessary to confirm that the analog input terminal of the controller matches the output terminal of the transmitter;
3. Do not install the transmitter when the temperature exceeds the working range;
4. The transmitter should be installed in a location that can effectively reflect the temperature of the measured area, and attention should be paid to keeping it away from heat or cold sources;
5. Construction personnel should wear anti-static gloves and cut off the power supply during installation and wiring, and should not operate with electricity;
6. If there is a significant temperature difference between the installation surface and the tested environment, it is recommended to use a bracket with a distance of 20CM for installation;
7. Some technical indicators of the product may be modified, and the indicators on the product label shall prevail.
7、quality assurance
Within 12 months of the product leaving the factory, free repair services will be provided based on normal use and non-human damage.
