Parameters 
MIN to MAX 
*RST value 
the stepping resolution of voltage of this unit. 
Query order 
VOLT:STEP? 
Return parameters 
<NR2> 
VOLT:PROTection{<vaule>|MINimum|MAXimum} 
This order is used to set the upper limit of over voltage protection point. If the 
output voltage value is higher than the upper limit of OVP, then we can assume 
that internal parts has been shorted. Query state register ”OV” bit has been set. 
When power supply is protected, then we can through order VOLT:PROT:CLE 
to clear the OVP state. 
Order syntax 
[SOURce:]VOLTage:PROTection[:LEVel] <NRf> 
Parameters 
MIN to MAX 
Unit 
V 
Query syntax 
VOLT:PROT? { MINimum|MAXimum} 
Return parameters 
<NR2> 
VOLT:PROTection:[STATe] {0|1|OFF|ON} 
This order is used to open or close OVP function i.e to set the state of OVP. 
Order syntax 
[SOURce:]VOLTage:PROTection:STATe 
Parameters 
0|1|OFF|ON 
Query syntax
