3. logger can be configured to start at your command using the magnet in the coupler to trigger a start 1 Use HOBOware to launch the logger with Using Coupler selected Remove the logger from the coupler 2 Bring the logger and an empty coupler or strong magnet to the deployment location Important Any magnet can trigger a start This can be helpful but it can also cause a premature start Keep the logger away from strong magnetic fields until you are ready to begin logging 3 When you are ready for the logger to start logging for example after connecting the logger to an external device such as a rain gauge insert the logger into the empty coupler or place it next to a strong magnet and remove it after three seconds Important The logger will not launch if the base station is in the coupler 4 Verify that the logger s light is blinking at least every four seconds Event Logging The external event channel records the times of transitions from an open contact to a closed contact The logger checks continuously for transitions When a transition occurs it is recorded as an event with a resolution of one second The external event channel has a built in lockout time of 500 milliseconds The lockout time serves to debounce mechanical switches To guarantee event capture the pulse must have a minimum duration of 1 millisecond Important If the logger is configured to log events only no temperature or battery

10. logging there may be a delay of up to an hour before logging begins or when relaunching Keep this delay in mind for deployment purposes Deploy the logger or relaunch it at a time when you will not need any data for an hour In addition if at least one channel is enabled for logging either temperature or battery and you are relaunching the logger with the HOBO Waterproof Shuttle the logger will use the logging interval to determine when to relaunch For example let s say the logging interval was set to 3 hours and only the battery channel was selected for logging When the logger is read out and relaunched with the shuttle logging including event logging will not begin for three hours the previously selected logging interval If you want to log temperature data it is recommended that you use a shorter logging interval to minimize the delay when relaunching with a logger It is not necessary to log battery data it is recommended that you disable that channel 1 800 LOGGERS HOBO Pendant Event Data Logger UA 003 Manual Like other U Series loggers this logger stores internal events that are unrelated to the external event inputs Internal events are stored when the coupler is attached or detached when the battery drops below approximately 2 7V when the battery rises above 2 8V when a host computer is connected and when the logger is stopped by a command from the host software Operation A light LED on the fr
