:APPLy Command
The :APPLy command provides the most straightforward method to program the power supply over the
remote interface. You can set the output voltage and current in one command. As long as their setting
values are within the settable range, after you execute the command, the output voltage and current will
make changes accordingly.
:APPLy
Syntax
:APPLy [<channel>,]{<voltage>|MINimum|MAXimum|DEF}[,<current>|MINimum|MAXimum|DEF]
:APPLy? [<channel>[,<item>]]
Description
Sets the channel output voltage and/or current.
Queries the channel voltage and/or current setting value.
Parameter
Name Type Range Default
<channel> Discrete
DP711
：
{CH1|P30V}
DP712：{CH1|P50V}
CH1
<voltage> Real
DP711: 0 V to 32 V
DP712: 0 V to 53 V
0 V
<current> Real
DP711: 0 A to 5.3 A
DP712: 0 A to 3.2 A
DP711: 5 A
DP712: 3 A
<item> Discrete {VOLTage|CURRent} --
Remarks
 <voltage> indicates the channel output voltage, and <current> indicates the channel output current.
If you specify only one parameter for the command, by default, the power supply regards it as the
voltage setting value.
 MINimum indicates setting the channel output voltage/current to a minimum value; MAXimum
indicates setting the channel output voltage/current to a maximum value; DEF indicates setting the
channel output voltage/current to a default value.
 If <item> is omitted, the command queries both the channel voltage and current setting values.
 You can also use the
[:SOURce[<n>]]:VOLTage[:LEVel][:IMMediate][:AMPLitude] command to set the
channel output voltage, and use the
[:SOURce[<n>]]:CURRent[:LEVel][:IMMediate][:AMPLitude]
command to set the channel output current.
Example
:APPLy CH1,5,1 /*Sets the channel output voltage to 5 V, the output current 1 A*/
:APPLy? /*Queries the channel voltage and current setting value*/
:APPLy 3 /*Sets the channel output voltage to 3 V*/
:APPLy? CH1,VOLTage /*Queries the channel voltage setting value*/
Return Format
A string
If all parameters are omitted or only the parameter <item> is omitted, the command returns both the
channel voltage and current setting values. For example, 5.00,1.00
Otherwise, only the channel voltage or current setting value is returned. For example, 3.00
