:PRESet:USER[n]:SET:OVP
Syntax :PRESet:USER[n]:SET:OVP {ON|OFF}[,<voltage>|MINimum|MAXimum]
:PRESet:USER[n]:SET:OVP? [MINimum|MAXimum]
Description Enable or disable the overvoltage protection function of the specified user-preset
state and set the overvoltage protection limit.
Query the status and limit of the overvoltage protection function of the specified
user-preset state.
Parameter
Name Type Range Default
[n] Discrete 1|2|3|4 None
{ON|OFF} Bool ON|OFF OFF
<voltage> Real
Voltage range of the
current channel
Maximum voltage of the
current channel
Explanation By default, this command sets the parameter of the channel currently selected. If
you want to set the parameter of other channel, please use
the
:INSTrument[:SELEct] command to select the desired channel.
Return Format The query returns OFF or ON,limit of overvoltage protection,for example, ON,8.800.
Example :PRES:USER1:SET:OVP ON,8.8
:PRES:USER1:SET:OVP?
:PRESet:USER[n]:SET:OTP
Syntax :PRESet:USER[n]:SET:OTP {ON|OFF}
:PRESet:USER[n]:SET:OTP?
Description Enable or disable the over-temperature protection function of the specified
user-preset state.
Query the status of the over-temperature protection function of the specified
user-preset state.
Parameter
Name Type Range Default
[n] Discrete 1|2|3|4 None
{ON|OFF} Bool ON|OFF ON
Return Format The query returns ON or OFF.
Example :PRES:USER1:SET:OTP ON
:PRES:USER1:SET:OTP?
