2. APPLy
:APPLy
Format
：
:APPLy [CH1|CH2|CH3|SER|PARA],[<volt>|MINimum|MAXimum], [<curr>|MINimum|MAXimum]
Function
：
Set the specified channel as the current channel, and set the voltage and current value for this
channel.
Description
：
“CH1, CH2”can only be selected in normal mode; “SER”can only be selected in serial mode;
“PARA”can only be selected in parallel mode. When“volt”and “curr”parameter is ignored at the same time, it
only sets the the specified channel as the current channel, not change the voltage and current value of
the channel.
For Example
：
:APPLy CH1,15.00V, 2.000A
:APPLy?
Format
：
:APPLy? [CH1|CH2|CH3|SER|PARA],[CURRent|VOLTage]
Function
：
Query the voltage and current value of a certain channel.
Description
：
If the channel parameter is ignored, then the current channel is the channel which need to be
queried by default. If it assigns “CURRent”, then return the current value; If it assigns “VOLTage”, then
return the voltage value; If it has no specified assignment, then return the voltage and current value.
For Example
：
:APPLy? CH1, VOLT
Return
：
CH1

15.00
3. INSTrument
:INSTrument[:SELEct]
:INSTrument[:SELect]
Format
：
:INSTrument[:SELect] {CH1|CH2|CH3|SER|PARA}
:INSTrument[:SELEct] {CH1|CH2|CH3|SER|PARA}
Function
：
Set the specified channel as the current channel.
Description
：
“CH1, CH2”can only be selected in normal mode; “SER”can only be selected in serial mode;
“PARA”can only be selected in parallel mode.
Set the power mode refer to the command “:SOURce:Mode {NORMal|SER|PARA}”
For Example
：
:INSTrument:SELE Ch3
:INSTrument[:SELEct] ?
:INSTrument[:SELect] ?
Format
：
:INSTrument[:SELEct] ?
:INSTrument[:SELect] ?
Function
：
Query the current channel.
Description
：
Return“CH1|CH2|CH3|SER|PARA”.
For Example
：
:INSTrument:SELE?
Return
：
CH1
