All HOBO and StowAway data loggers shut off when the memory is full (unless wrap-around is selected) or the data is downloaded to a computer. Once the data is downloaded to the computer, the data logger is in off mode and will need to be relaunched to continue data collection. If the data logger you are using is shuttle-compatible and you are downloading to a shuttle, the shuttle will automatically relaunch the data logger using the previous settings. The HOBO Weather Station, Micro Station, and Water Temp Pro give you the option at readout to "Stop Logging and Off-load Data," or to "Off-load While Logging." Off-load While Logging will allow the data logger to continue recording data in the current deployment.
