R,X graph - series model R||,X|| graph - parallel model
In these graphs, positive values of reactance (X) correspond to inductive load, while
negative values correspond to capacitive load. Please notice the difference in the plots
when series or parallel model of impedance is selected through the Settings menu.
[Please notice that RigExpert AA-500 displays absolute value of the reactance, |X|.]
4.3.3. Memory operation
In the SWR graph and R,X graph modes, you may choose to scan to memory (the 6
key). There are 100 memory slots available. Later, you may recall ( 9 ) the plots from
