| Launch Modes : | Immediate start and delayed start | |
| Offload Modes : | Offload while logging; stop and offload | |
| Battery Indication : | Battery voltage can be viewed in status screen and optionally logged in datafile. Low battery indication in datafile. | |
| CE | The CE Marking identifies this product as complying with all relevant directives in the European Union (EU). | |
| * Water Level Accuracy: | With accurate reference water level measurement, known water density, accurate Barometric Compensation Assistant data, and a stable temperature environment. | |
| ** Raw Pressure Accuracy: | Absolute pressure sensor accuracy includes all sensor drift, temperature, and hysteresis-induced errors. | |
| *** Changes in Temperature: | Allow 10 minutes in water to achieve full temperature compensation of the pressure sensor. Maximum error due to rapid thermal changes is approximately 0.5%. | |
