The Datalogger retains its stored readings even when the battery is discharged or when the battery is replaced; the data logging process will
however be stopped and cannot be re-started until the battery has been replaced and the logged data has been downloaded to PC.
Use only one (1) 3.6V lithium battery (1/2 ‘AA’). Before replacing the battery, disconnect the datalogger from the PC.
NOTE: Leaving the datalogger plugged into the USB port for longer than necessary will shorten the battery life.
