8 Application Operations (Continued) Graph displays (names and functions of parts) When data is received, the first display to appear shows graphs for all channels (ALL display). This section explains the parts shown in ALL display and individual display .
9 1 Menu bar and menu icons Y ou can choose the following commands from the application menus. File Open Opens a file that has been saved on the PC (see page 13) . Close Closes a file. Save Save measurement data in a file (see page 12) . Save As Receive Receives measurement data (see page 7) .
10 Application Operations (Continued) 2 Date and time Display the date and time when the measur ement data was transferred to the PC. 3 Channel and frequency switch buttons Ch: Selects channel display mode (frequencies ar e displayed along graph depth axes).
11 9 Bar Graph Changes the type of graph display . The display switches between the band graph and bar graph by pressing this button. 10 File memo Allows you to recor d memos about conditions when the measurements wer e made. 11 Fr eq [Hz]/Channel In channel display mode, it becomes the fr equency axis.
