Data analysis in tandem with a PC Dedicated PC application program bundled as standard accessory n Pseudo real-time MEM data recording to media With automatic saving, the memor y recorder saves instantaneous waveform data into the media in batches. Data is saved to media using a method designed to minimize the time for which measurement is not possible (dead time).
