GDM 8342 provides USB flash drive storage function which allows users to conveniently save data into a USB flash drive through a simple and proper setting This unique function different from other digital multimeters which must first save data into its own internal memory then transfer out the file or connect multimeters with a computer to retrieve data not only saves operational time but also cuts down the cost and time of developing programs The USB flash drive storage function incorporates two modes basic and advanced which can be selected from the front panel When the basic mode is on data will be saved into an automatically established new folder time of established file will be determined by system default and the starting time of data logging will use a fixed time marker OOhr OOmin OOsec For advanced mode users can designate a file path to save data or establish a new folder and the starting time of data logging is determined by users inputs for instance 23hr 45min 32sec The number of data files can be saved in one second is determined by the speed of selected function The USB storage function allows each flash drive to establish 100 folders GW000 GW099 Each folder has a capacity of saving 5 000 000 data files which are divided into 100 sub file names therefore each sub file name can save 50 000 data files Take folder GW000 as an example internal file names are GDM834x Series NPI Announcement
