6、Power on process (if the display module is not included at the factory, the transmitter will not display information)
After powering on the transmitter for 0.5 seconds, the display screen will not display. After 0.5 seconds, the display screen will be fully lit to check the status of the display screen. Display temperature range code tEP after 0.5 seconds; Display customer customized code Fad after 0.5 seconds; If the transmitter has a malfunction, a fault code Err will be displayed. If the transmitter is in a normal state, there will be no error code Err displayed and the temperature and humidity display mode will be entered directly.
7、Display code description: (If there is no display module at the factory, the transmitter will not display information)
TEP: represents the humidity range set by the current encoder of the transmitter, with values ranging from 000 to 007, as shown in Table 2.
FAd ：Indicates the custom code for the transmitter, with values ranging from 000 to 999, and the standard version code is "000".
Err：Fault codes. When displaying 005, it indicates that the sensor connection wire is disconnected or the sensor is faulty

9、Dimension：
10、Dimension
1. Please read this manual carefully before use to ensure correct wiring. This product has anti reverse connection protection measures, but incorrect wiring that exceeds the rated parameters for a long time can still cause product malfunctions.
2. Please install in a well ventilated area, away from areas with local heating.
3. Prevent direct infringement of sensors by chemical reagents, oil, dust, etc
4. Long term use of the transmitter may cause offset, and to ensure measurement accuracy, it is best to calibrate it once a year.
5. Try to stay away from high-power interfering equipment to avoid measurement errors, such as frequency converters, motors, etc.
