Zooming In or Out on the Time Axis
You can adjust the time span. The zoom factor of the time axis is displayed at the lower

Time-Axis menu.
Zoom In
Zoom Out
The waveform is displayed after zooming in or out of the time axis.
Note
• There are 14 zoom factors: 1/1000, 1/500, 1/200, 1/100, 1/50, 1/20, 1/10, 1/5, 1/2, 1, 2, 5,
10, and 20.
However, the minimum zoom factor that can be displayed varies depending on the number
of pixels in the waveform display area. Therefore, the minimum zoom factor that can be
displayed varies depending on the monitor screen size.
• The absolute and relative time format (example: MM/DD HH:MM or HH:MM:SS)
automatically switches depending on the zoom factor.
Choose Time-Axis > Scale from the menu bar to open the Time Axis Scale dialog box.
You can expand or reduce the time axis at an arbitrary factor that you enter.
• Zoom in range: 1 to 20 (whole number)
• Zoom out range: 1/1 to 1/1000 (the denominator is a whole number)
Choose All from the Time-Axis menu to adjust the zoom factor so that all the data can be
displayed on the waveform display screen.
