  • Answer:

    This is a data acquisition device (DAQ) not a data logger.  It is designed to send data while connected via USB to a PC.  Because of this it doesn't have any onboard memory or stand-alone functionality.

    It can be programed to record in a circular buffer mode but only to a PC running software.
