[SOURce:]VOLTage:PROTection:TRIGgered? 
This command is used to inquire the executing state of over voltage protection.If return 
“1”,this indicates the OVP circuit has been triggered and the OVP state does not be cleared.If 
return “0”,which means OVP circuit is not be triggered. 
Command syntax:[SOURce:]VOLTage:PROTection:TRIGgered? 
Return value:0|1 
 
[SOURce:]VOLTage:PROTection:CLEar 
This command is used to clear the OVP state.Before sending this command,please increase 
the upper limitation of OVP or you can also reduce the output voltage. 
Note:Please remove the external power supply which caused this protection and then send 
this command.
