[Elecraft] Identifying KAT500 fault condition

[Andy Durbin]

When the KAT500 trips a fault the fault light is lit but, unlike KPA500, there is no front panel indication of which fault is active.  One would expect the KAT500 Utility to display information on the active fault but it does not.  E.g. -

KAT500 Utility (for Windows) ver 1.19.8.5 displays "No Fault" when FLT1 - No Match is active.

The currently active KAT500 fault can be identified by using the utility command tester.  Select the Command Tester tab.  Press "Clear".  Enter FLT;  in the command entry box.   The display box will then show FLT; and FLTx; where x is the current fault code.  Fault codes are documented in KAT500 Serial Command Reference.
