Return parameters 
0|1 
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.

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.

[SOURce:]VOLTage:RANGe[high/low] 
IT6860A/IT6860B/IT6870A/IT6870B series are dual-range power supply. This 
order is used to set the voltage range of the instrument.
