[SENSe:]CURRent[:DC]:RANGe

Syntax

[SENSe:]CURRent[:DC]:RANGe {<range>|MIN|MAX|DEF} [, (@<ch_list>)]

[SENSe:]CURRent[:DC]:RANGe? [{(@<ch_list>)|MIN|MAX}]

Description

This command selects the measurement range for dc 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

Name

Type

Range of Values

Default Value

<range>

Discrete

Desired range in amps:

10 mA (MIN)
100 mA
1 A (MAX)

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[:DC]: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 enables 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:DC:RANG 0.1,(@1041,1042)

The following query returns the range selected on channels 41 and 42 in slot 1.

CURR:DC:RANG? (@1041,1042)

Typical Response:  +1.00000000E-01,+1.00000000E-01
