Parameter
Name Type Range Default
<channel> Discrete
DP711: {CH1|P30V}
DP712: {CH1|P50V}
CH1
<value> Real
Standard: 0.01 V to 33 V
High resolution option (ordering number:
HIRES-DP700) installed: 0.001 V to 33 V
32 V
Remarks
 If the overvoltage protection function is enabled and the voltage of the output terminal equals to the
currently set overvoltage protection value, then the internal OVP flag is set to 1, and a message is
displayed on the screen, prompting you that overvoltage protection occurs and the channel output is
automatically disabled.
 For the setting command, MINimum indicates setting the channel overvoltage protection to a minimum
value; MAXimum indicates setting the channel overvoltage protection to a maximum value.
For the query command, MINimum indicates querying the minimum settable value of the channel
overvoltage protection; MAXimum indicates querying the maximum settable value of the channel
overvoltage protection.
 You can also send the
:OUTPut:OVP:VALue command to set the channel overvoltage protection value.
Example
:VOLTage:PROTection 30 /*Sets the channel overvoltage protection value to 30 V*/
:VOLTage:PROTection? /*Queries the channel overvoltage protection value*/
Return Format
A real number.

Syntax
[:SOURce[<n>]]:VOLTage:PROTection:STATe <state>
[:SOURce[<n>]]:VOLTage:PROTection:STATe?
Description
Enable or disable the overvoltage protection (OVP) function.
Queries the on/off state of the overvoltage protection (OVP) function.
Parameter
Name Type Range Default
<n> Discrete {1} 1
<state> Bool {ON|OFF} OFF
Remarks
 Overvoltage protection indicates that when the channel output voltage equals to the overvoltage
protection value, the internal OVP flag is set to 1, and a message is displayed on the screen, prompting
you that overvoltage protection occurs and the channel output is automatically disabled. At this time,
you can send the
:OUTPut:OVP:CLEAR or [:SOURce[<n>]]:VOLTage:PROTection:CLEar command to
clear the internal OCP flag and the OCP prompt message.
 You can also send the
:OUTPut:OVP[:STATe] command to enable or disable the overvoltage protection
function.
