Features
1. Wide detection range, it can respond to the spectral range of 400700nm, widely used in the research of meteorology, agriculture, air pollution and other fields.
2. With an allaluminum shell, its protection grade is IP67, which is compact and beautiful, making it more convenient for research.
3. Equipped with a level gauge and an adjustment handwheel, it is convenient for onsite adjustment and can cope with research in different situations.
4. Adopt highquality cosine corrector, it uses wide voltage power supply DC 730V to ensure the cosine response standard.
5. Proportional rightangle cosine, when there is light, it produces a voltage signal proportional to the strength of the incident radiation, and its sensitivity is lower than that of incident light.
6. Adopting a specially treated dust cover, it can reduce dust absorption, effectively prevent environmental factors from interfering with internal components, and can more accurately measure photosynthetic active radiation.
7. Using standard RTU 485 communication protocol, it can directly read the current effective radiation value, and the wiring method is simple.

Using RTU communication rules, the format is as follows:
Initial Structure: 4 Bytes Time
Address Code:= 1 Byte
Function Code:= 1 Byte
Data Area:= N Bytes
Incorrect Version:= 16 Bytes CRC Code
End Structure: 4 Bytes Time
Address Code: The address of the transmitter, which will be the only one in the communication network (factory default 0x01).
Function Code: Command function commands from the host, this transmitter only uses function code 0x03 (read register date).
Data Area: The data area is the specific communication data. Pay attention to the high byte of the previous 16-bit data.
CRC Code: Double-Byte Correction Code.
Troubleshooting:
-
If the read value is 0, check whether there is a light source, and check whether the product protective cover has been removed.
-
Please check whether the 485 wiring is correct and whether the wiring is reversed.
-
Check whether the device address of the vehicle is wrong, or there are devices with duplicate addresses (the factory default is 1).
-
Check whether the power supply meets the mark.
-
The equipment is damaged.
Product Maintenance:
-
The shell of the product should be kept fluent and clean, and wipe it regularly with a soft cloth.
-
Please regularly check whether it is level and whether the screws are loose.
