Why does the alarm, Red, LED on the logger still blink even when the logger has finished?
This feature is provided so that you are aware that the logger was in alarm mode when the logger finished its logging. When monitoring temperature sensitive cargo, for example, this feature is extremely useful to give an immediate indication that the cargo may not be in an acceptable condition. You may stop the alarm, Red, LED flashing by swiping a magnet over the logger in a similar fashion to starting the logger.
