Overview
The wireless temperature transmitter adopts FSTN high-definition segment code liquid crystal, which is suitable for up to ten kinds of thermocouple and thermal resistance signal transmission. The product uses a 24-bit ∑-△ analog front end to ensure high accuracy of measurement; perfect anti-surge, anti-lightning and anti-reverse design to avoid misinstallation and misoperation in engineering applications; enhanced software safety design, including low-voltage monitoring reset, multi-task scheduling optimization and other functions. 2.4GHz wireless communication has the characteristics of long propagation distance and fast networking speed. All imported components are used to ensure long service life and stability.

Instructions for Use (Required)
In order to ensure the normal use of the battery, the instrument is suitable for storage and use in the ambient temperature of -30 ℃ ~ 60 ℃, humidity is less than 80% occasions:
2. The instrument shall be connected to the power supply according to the wiring method of section 3. After confirming the operation is correct, the power can be connected to the operation: In addition, when the user installs the sensor by themselves, when disassembling the head, please pay attention to avoid damage to the extension line of the antenna, otherwise it will seriously affect the communication quality;
3. The transmission distance is greatly affected by the on-site environment: usually in the case of straight line transmission, can reach 1500 meters: in the workshop of cement brick structure, the transmission distance can reach about 200 meters: in the large area of metal structure in the workshop, the transmission distance may be lower. Therefore, when setting up the wireless system, the transmitter and collector should be minimized: 4. Wireless system installation, should ensure that the transmitter and concentrator antenna direction parallel.
