10. Troubleshooting
A common cause for erroneous, turbidity-sensor data is poor sensor
connections to the datalogger.
Problem:
Unit will not respond when attempting serial communications.
Suggestion:
Check the power (Red is +V and Black is Ground) and signal (White is SDI-12
Data) lines to ensure proper connection to the datalogger. Check the
datalogger program to ensure that the same port the SDI-12 data line is
connected to is specified in the measurement instruction.
