For Modbus CRC Checksum Steps:
1. Initialize a 16 bit register to hex FFFF, referred to as the CRC register.
2. XOR the first 8 bits of data with the low byte of the CRC register and store the result in the CRC register.
3. Right shift the contents of the register by one bit, filling the highest bit with 0, and check the lowest bit.
4. If the lowest bit is 0: Repeat step 3 (shift again). If the lowest bit is 1: XOR the CRC register with the polynomial A001 (1010 0000 0000 0001).
5. Repeat steps 3 and 4 for a total of 8 shifts, processing the entire 8 bit data.
6. Repeat steps 2 to 5 for the next 8 bit data. The final CRC register obtained is the CRC code (low byte first, high byte last).
Troubleshooting:
The displayed value on the instrument is incorrect during output. This may be due to wiring issues or communicating port failure, preventing the correct data acquisition. Please check the wiring for correctness and stability, make sure the serial port is not being used by other devices, and verify the serial port settings are correct.
How to Use:
1. Make sure the mounting bracket is parallel to the ground.
2. Secure the sensor to the mounting bracket through the two mounting holes on the sensor using M3 screws and nuts.
3. Avoid disassembling the sensor during installation.
