| Logging Rate | 1 second to 18 hours |
| Logging Modes | Fixed interval, multiple intervals with up to 8 user-defined logging intervals and durations, or event-triggered burst |
| Memory Modes | Wrap when full or stop when full |
| Start Modes | Immediate, date & time, or next interval |
| Stop Modes | When memory full, stop with HOBOmobile, date & time, or after a set logging period |
