  • Page 36: File Names Created Or Renamed Externally

    5.6.1.1 File Names Created or Renamed Externally Files may be created externally or created within the instrument and renamed externally (e.g. using Link to PC mode). Such files may have long file names and/or include lower case characters and additional characters such as ?. The instrument will correctly list all such files that conform with an 8.3 naming system and which have the correct extension for the relevant folder.

  • Page 37: Using An External Flash Drive

    It should be noted that CDC is used only for screen data exchange when View on PC is selected. It is not possible to transfer file data while in this mode. To exchange files between instrument and PC requires MSC and in this mode View on PC is not available. The user can, however, switch freely between these modes by executing the key sequences above but connection to the View on PC application will be lost when Link to PC is selected.
