[SENSe:]CURRent:AC:RANGe
Syntax
[SENSe:]CURRent:AC:RANGe {<range>|MIN|MAX|DEF} [, (@<ch_list>)]
[SENSe:]CURRent:AC:RANGe? [{(@<ch_list>)|MIN|MAX}]
Description
This command selects the measurement range for ac current measurements on the specified channels. If you omit the optional <ch_list> parameter, this command applies to the internal DMM, independent of any channels or a scan list.
Used With:
34921A Armature Multiplexer (channels 41 through 44 only)
Parameters

Range of Values |
Default Value |
|
<range> |
Discrete |
Desired range in amps: 10 mA (MIN) |
This is a required parameter |
|
<ch_list> |
Numeric |
One or more channels in the form (@sccc). Current measurements are allowed only on channels 41 through 44 on the 34921A. |
If <ch_list> is omitted, this command applies to the internal DMM. |
Remarks
If you omit the optional <ch_list> parameter, the configuration applies to the internal DMM, independent of any channels or a scan list (any existing scan list is not redefined). An error is generated if the internal DMM is not installed or is disabled.
Selecting a discrete range will disable autoranging on the specified channels (see [SENSe:]CURRent:AC:RANGe:AUTO command).
The CONFigure and MEASure? commands automatically enable autoranging.
If the input signal is greater than can be measured on the selected range (manual ranging), the instrument gives an overload indication: "±OVLD" from the front panel or "±9.9E+37" from the remote interface.
The instrument selects autoranging after a Factory Reset (*RST command). An Instrument Preset (SYSTem:PRESet command) or Card Reset (SYSTem:CPON command) does not change the setting.
Return Format
The query command returns the range in the form "+1.00000000E-01" for each channel specified. Multiple responses are separated by commas.
Examples
The following command selects the 100 mA range on channels 41 and 42 in slot 1.
CURR:AC:RANG 0.1,(@1041,1042)
The following query returns the range selected on channels 41 and 42 in slot 1.
CURR:AC:RANG? (@1041,1042)
Typical Response: +1.00000000E-01,+1.00000000E-01
