Pressing the Save File button saves all the records downloaded from the instrument to a file on the PC. In addition to the whole contents of the recording memory the file also contains ancillary information, such as calibration, instrument information…etc.
The file is saved in a proprietary format with the extension .cil.
By default the file is saved with a name that contains the User-ID of the instrument, if any has been set, as well as the present date and time.
