Test steps:
1. The default 16-bit register is hexadecimal and will called CRC register;
2. The first 8-bit data is different from the lower part of the CRC register or enter the result into the CRC register;
3. Shift the contents of the register to the right (down) by one bit, fill the highest bit with 0 and check the lowest bit;
4. If the lowest position is 0: repeat step 3 () If the lowest position 1 is: The CRC register is The result of the CRC register is the CRC code (the result of the CRC code is low before high after).
Installation location requirements:
1. Good air circulation around
2. Keep away from exhaust vents, motors and other equipment
3. Keep away from areas such as water, fountains and sprinklers

How to use:
Install and use it according to the applicable voltage
