1、High Accuracy Measurement: The photoelectric total radiation sensor can measure solar total radiation in the spectrum range of 0.3-1.1μm. When the sensing surface is downward, it can measure reflective radiation. Additionally, with shading rings, it can measure diffuse radiation. 2、Advanced Core Device: At the core of the radiation sensor is a high accuracy photosensitive elements, which boasts excellent stability and high accuracy. It is enough to measure the amount of solar radiation more accurately. 3、Protective Quartz Glass Cover: A precisely optically cold processed quartz glass cover has been installed outside the sensing elements to effectively prevent external environmental factors from impacting its performance. 4、Protective: This cover protects the sensor during transportation and under extreme weather conditions. In order to use the sensor, this cover needs to be unscrewed and removed. 5、Wide Application: Photoelectric total solar radiation sensor is suitable for various fields including meteorology, energy, and construction. Small and beautiful appearance, small installation space.

For Modbus CRC Verification Steps:
1. Pre set a 16bit register to hexadecimal FFFF, this register is called the CRC register.
2. XOR the first 8-bit data with the low end of the CRC register and put the result in the CRC register.
3. Right shift the contents of the register by one bit (towards the low end), fill in 0 at the highest end, and check the lowest end.
4. If the lowest end is 0: repeat step 3 (shift again) if the lowest end is 1: The CRC register XORs with polynomial A001 (1010 0000 0000 0001).
5. Repeat steps 3 and 4 until you shift right 8 times. This processes the entire 8bit data.
6. Repeat steps 2 to 5 to process the next 8bit data.
The final CRC register is the CRC code (the obtained CRC code is low before high).
Troubleshooting:
The instrument shows incorrect values during output. This may be due to wiring problems or communicating port failures which prevent the correct data from being obtained. Please check whether the wiring is correct and secure, whether the serial port is occupied, and whether the settings of the serial port are correct.

Note
1. Please check whether the packaging is intact and whether the product model corresponds with the selected one.
2. Do not connect the power before finishing wiring, the sensor can only be powered up after the connection is confirmed to be correct.
3. The length of the sensor wire will affect the product's output signal, do not arbitrarily modify it during use.
4. Sensors are accuracy devices. Users should not disassemble them arbitrarily, to avoid damaging the product.
5. The cover needs to be removed when using the sensor.
