Common failure analysis:
۱٫ Turn on the power indicator light but the host computer software can not connect the module:
Encountered the general inspection of the following key points:
۴۸۵ communication A, B line connection is correct
Serial port baud rate, stop bits, parity and other parameters are correct
The DIP switch address of the device is the same as that of the PC software
۴۸۵ cable length is not shielded
۲٫AD word is fixed to a large number, the value does not change with the sensor
Sensor connection error
The sensor has been damaged
۳٫AD word fluctuations can not be calibrated, measurement
Module supply voltage is low, or ripple large
Defective sensor wiring
Sensor cable length, without shielded wire
