5、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;
6、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.
