The LEDs give a status update & show whether the temp has exceeded an alarm condition at any point. When a logging session is finished, simply tear open the waterproof wallet to reveal the USB connector & plug into your PC. The logger will then automatically generate a PDF report that you can save to your PC. The "Plug & Play" functionality & compact, lightweight design of this logger make it ideal for logistics use.An alarm feature is available upon request. This is designed to trigger if the temperature has been within a specified range for a specified amount of time through the duration of the whole log. There will be an LED indication when you are in the cumulative alarm region (both LEDs flash) but an alarm will not be triggered until the specified amount of time has been exceeded.
