[Elecraft] KXAT2 ATU MD Menu

[VE2PID]

Hi ... In the KXAT2 menu, there is an option to check relays:  In ATU MD 
Modes L1-L7, C1-C7 and Ct are used to test the KXAT2's relays and 
L-network. However, I dont see any detailed infos of how to use it and 
what results should be expected ??

Any information would be welcome.
