CRS451/CRS456 Submersible Water-Level Recording Sensor 

9.  Troubleshooting 

The most common causes for erroneous pressure transducer data include: 

•

 

Low battery 

•

 

Damaged CRS451/CRS456 

   Water damage 

   Damage to diaphragm due to excessive pressure 

•

 

Atmospheric pressure not subtracted from pressure reading 

Problem: 

Unit will not respond when attempting USB communications. 

Suggestion: 

Replace battery. 

Correct COM Port used for communication not selected in HydroSci.
