[SENSe:]CURRent:AC:RANGe
[SENSe:]CURRent:DC:RANGe

Syntax

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

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

Description

These commands select the measurement range for AC and DC current measurements on the specified channels.

Used With:

34901A 20 Channel Multiplexer (2/4-wire) Module (channels 21 and 22 only)

Parameters

Name Type Range of Values Default Value

<range> Discrete
Expected value in amps (ranges shown below).

10 mA (MIN)
100 mA
1 A (MAX)
This is a required parameter.

<ch_list> Channel List
One or more channels, as shown:

(@321) - channel 21 on the module in slot 300.

(@221:222) - channels 21 through 22 on the module in slot 200.

(@121:122,222,321:322) - channels 21 and 22 on the module in slot 100, channel 22 on the module in slot 200, and channels 21-22 on the module in slot 300.

Note that the channels must be of the form s21 and s22, where s is the first digit of the slot number.
If you omit the optional <ch_list> parameter, this command applies to the currently defined scan list.

Name	Type	Range of Values	Default Value
<range>	Discrete	Expected value in amps (ranges shown below). 10 mA (MIN) 100 mA 1 A (MAX)	This is a required parameter.
<ch_list>	Channel List	One or more channels, as shown: (@321) - channel 21 on the module in slot 300. (@221:222) - channels 21 through 22 on the module in slot 200. (@121:122,222,321:322) - channels 21 and 22 on the module in slot 100, channel 22 on the module in slot 200, and channels 21-22 on the module in slot 300. Note that the channels must be of the form s21 and s22, where s is the first digit of the slot number.	If you omit the optional <ch_list> parameter, this command applies to the currently defined scan list.

Remarks

Selecting a discrete range will disable autoranging on the specified channels (see [SENSe:]CURRent:AC:RANGe:AUTO and [SENSe:]CURRent:DC:RANGe:AUTO commands).
The CONFigure and MEASure? commands automatically enable autoranging if the first parameter is AUTO, DEF or omitted.
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 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 21 and 22 in slot 100.

CURR:AC:RANG 0.1,(@121,122)

The following query returns the range selected on channels 21 and 22 in slot 100.

CURR:AC:RANG? (@121,122)

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