4.1.3 Display mode
In the display mode setting, representation methods of graphic display for analyzed data on the
LCD screen, i.e., gain (or amplitude) vs. phase, are specified/set.
The display mode is set through the menu [Graph][FORMAT][DISPLAY MODE]. The data
displayed in the graph depend on the analysis mode setting.
