:MEASure Commands
Command List:
 :MEASure:ALL[:DC]?
 :MEASure:CURRent[:DC]?
 :MEASure:POWEr[:DC]?
 :MEASure[:VOLTage][:DC]?
:MEASure:ALL[:DC]?
Syntax :MEASure:ALL[:DC]? [{CH1|CH2|CH3}]
Description Query the voltage, current and power measured internally on the specified channel.
Parameter
Name Type Range Default
[{CH1|CH2|CH3}] Discrete CH1|CH2|CH3 None
Explanation  If the parameter is omitted, the command queries the voltage, current and
power of the channel currently selected.
 You can send the
:MEASure:CURRent[:DC]?, :MEASure:POWEr[:DC]?
and
:MEASure[:VOLTage][:DC]? commands to query the current, power and
voltage respectively.
Return Format The query returns the voltage, current and power separated by commas, for
example, 5.0000,1.0000,5.000.
Example :MEAS:ALL? CH1 /*Query the voltage, current and power of CH1 and the query
returns 5.0000,1.0000,5.000*/

:MEASure:CURRent[:DC]?
:MEASure:POWEr[:DC]?
:MEASure[:VOLTage][:DC]?
:MEASure:CURRent[:DC]?
Syntax :MEASure:CURRent[:DC]? [{CH1|CH2|CH3}]
Description Query the output current measured internally on the specified channel.
Parameter
Name Type Range Default
[{CH1|CH2|CH3}] Discrete CH1|CH2|CH3 None
Explanation  If the parameter is omitted, the command queries the current of the channel
currently selected.
 You can send the
:MEASure:POWEr[:DC]? and :MEASure[:VOLTage][:DC]?
commands to query the power and voltage respectively, or send
the
:MEASure:ALL[:DC]? command to query the voltage, current and power at
the same time.
Return Format The query returns the current, for example, 1.0000.
Example :MEAS:CURR? CH1 /*Query the current of CH1 and the query returns 1.0000*/
