Tips and troubleshooting
Using a voltmeter, check the voltage of the primary power source at the
CHG and BATterminals 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.
- Check wires and cables for the following:
- Incorrect wiring connections. Make sure each sensor and device are wired to the terminals assigned in the program. If the program was written in Short CutA CRBasic programming wizard suitable for many data logger applications. Knowledge of CRBasic is not required to use Short Cut., check wiring against the generated wiring diagram. If written in CRBasic EditorThe CRBasic programming editor; stand-alone software and also included with LoggerNet, PC400, and RTDAQ software., check wiring against each measurement and control instruction.
- Loose connection points
- Faulty connectors
- Cut wires
- Damaged insulation, which allows water to migrate into the cable. Water, whether or not it comes in contact with wire, can cause system failure. Water may increase the dielectric constant of the cable sufficiently to impede sensor signals, or it may migrate into the sensor, which will damage sensor electronics.
Check the CRBasicCampbell 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 Short 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 CRBasic 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.
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).
