5.4 Operation method
FRA5087 5-8
5.4.2 Graph units setting
The impedance display option adds units setting to the menu [DISPLAY MODE] [FORMAT]
[DISPLAY MODE].
The display units setting is selected for gain and impedance.
The graph display units are determined by [UNITS] and [ANALYSIS MODE] setting. Display
units are indicated in Table 5-3.
Impedance display is fixed at voltage for CH1 input and current for CH2 input.
