After pressing Measure, the Channel Selection Window appears. Choose the new file name for the record file. The extension will be automatically added. An automatic filename increment can be selected. If a number is added to the filename, this number is incremented each time the recording starts new. If you do not want to write the file to the default path, press the View button and select a different path. The available memory on the selected volume is shown. All channels which were defined by an instrument are listed here and can be selected (green LED = on). Use the vertical slider on the left side to move to higher channel numbers. The Setup file also contains all information about the selected channels and the text input in the field Diagnostics.
