6. Things to note
1、When the transmitter is connected to the controller, it is recommended to use 18-24 to prevent noise interference. AWG Shielded cables;
2、Before turning on the power supply, it is necessary to confirm that the analog input of the controller matches the output of the transmitter;
3、Do not install a transmitter when the temperature exceeds the operating range;
4、The transmitter should be installed at a position that can effectively reflect the temperature of the measured area, and be careful to stay 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 live;
6、If there is a large temperature difference between the installation surface and the environment under test, it is recommended to use a bracket distance of 20 CM Install;
7、Some technical indicators of the product may be modified, and the indicators on the product logo shall prevail.
