Tips and troubleshooting

Start with these basic procedures if a system is not operating properly.

  1. Using a voltmeter, check the voltage of the primary power source at the CHG and BAT terminals on the face of the data logger, it should be 10 to 18 VDC. If connecting to a power source via the CHG terminals, voltage measured should be 16 to 32 VDC.

  2. Check wires and cables for the following:
  3. Check the ClosedCRBasicCampbell Scientific's BASIC-like programming language that supports analog and digital measurements, data processing and analysis routines, hardware control, and many communications protocols. program. If the program was written solely with ClosedShort CutA CRBasic programming wizard suitable for many data logger applications. Knowledge of CRBasic is not required to use Short Cut., the program is probably not the source of the problem. If the program was written or edited with ClosedCRBasic EditorThe CRBasic programming editor; stand-alone software and also included with LoggerNet, PC400, and RTDAQ software., logic and syntax errors could easily have crept in. To troubleshoot, create a simpler version of the program, or break it up into multiple smaller units to test individually. For example, if a sensor signal-to-data conversion is faulty, create a program that only measures that sensor and stores the data, absent from all other inputs and data.

  4. Reset the data logger. Sometimes the easiest way to resolve a problem is by resetting the data logger (see Resetting the data logger for more information).
