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.
