VOLT:PROTection:TRIPed? 
This order is used to inquire the execute state of OVP. If the return value is “1”, 
this represents that the OVP circuit has been triggered and the OVP state does 
not be cleared. If the return value is “0”,then it represents the OVP circuit does 
not be triggered. 
Order syntax: 
[SOURce:]VOLTage:PROTection:TRIPed? 
Return parameters: 
0|1 
VOLT:PROTection:CLEar 
This order is used to clear the state of OVP. After you executing this order, the 
output value will be restored to the previous output and the upper limit of OVP 
will be kept. Of course, before you sending this order, you should enable the 
output voltage lower than the upper limit of OVP. In addition, please note that 
making sure to remove the external power supply before you sending this 
order. 
Order syntax: 
[SOURce:]VOLTage:PROTection:CLEar 
VOLT:LIMIT <volts> 
This order is used to set the upper limit of the output voltage. 
Order syntax:

Parameters: 
MIN to MAX 
Unit: 
V 
Query syntax: 
VOLTage:LIMIT? 
Return parameters: 
<NR2>
