VOLTage:PROTection? {MINimum|MAXimum};
This query returns the overvoltage protection trip level presently programmed. 
VOLT:PROT? MAX
 and 
VOLT:PROT? MIN
 return the maximum and minimum 
programmable overvoltage trip levels.
VOLTage:PROTection:STATe {0|1|OFF|ON}
This command enables or disables the overvoltage protection function. An 
overvoltage condition can be cleared with the 
VOLT:PROT:CLE
 command after 
the condition that caused the OVP trip is removed. At 
*RST
, this value is set to 
“ON”.
VOLTage:PROTection:STATe?
This query returns the state of the overvoltage protection function. The 
returned parameter is “0” (OFF) or “1” (ON).
VOLTage:PROTection:TRIPped?
This query returns a “1” if the overvoltage protection circuit is tripped and not 
cleared or a “0” if not tripped.
VOLTage:PROTection:CLEar
This command causes the overvoltage protection circuit to be cleared. After 
this command, the output voltage is restored to the state it was in before the 
protection feature occurred and the OVP trip level remains unchanged to the 
value presently programmed. Before sending this command, lower the output 
voltage below the trip OVP point, or raise the OVP trip level above the output 
setting. 
Note that the overvoltage condition caused by an external source must be 
removed first before proceeding this command.
