Product Instructions:
1. This product is not suitable for long-term condensation and chemical pollution environment, to prevent chemical agents, oil, dust and other direct damage to the sensor. Remember not to carry out cold and thermal shocks.
2. Check carefully before use to ensure correct wiring. The positive and negative poles of the power supply can be reversed. The power supply of this product is not divided into positive and negative poles. The communication line needs to be connected correctly according to RS485A and RS485B, otherwise it will not be able to communicate.
3. Temperature and humidity measurements are not accurate when heat transfer and temperature differences between the test area and the test area are avoided.
4.Installed in a stable environment, avoid direct lighting, away from windows and air conditioning, heating and other equipment, avoid direct to the window, door.
5. Try to avoid high-power interference equipment, so as not to measure inaccurate, such as inverters, motors, etc.
6. If you want to disassemble the product, you must first disconnect the power supply before disassembling.
7. This transmitter is indoor type to prevent water from entering inside the transmitter to avoid damage.
8. One year from the date of purchase, and the product is a lifetime service, after the warranty period we bear the cost of maintenance.
9. If you encounter some problems during use, please do not disassemble and repair the product, please contact our customer service staff to solve some problems you encounter under the guidance of the engineer.
Package Includes:
1 x WTR10-E Temperature Humidity Transmitter Sensor
