[SENSe:]FRESistance:RANGe

Syntax

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

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

Description

This command selects the measurement range for 2-wire (RESistance) and 4-wire (FRESistance) resistance measurements on the specified channels.

Used With:

34901A 20 Channel Multiplexer (2/4-wire) Module
34902A 16 Channel Multiplexer (2/4-wire) Module
34908A 40 Channel Single-Ended Multiplexer Module (RESistance only; not FRESistance)

Parameters

Name Type Range of Values Default Value

<range> Discrete
Desired range in ohms:

100Ω (MIN)
1 kΩ
10 kΩ
100 kΩ
1 MΩ
10 MΩ
100 MΩ (MAX)
This is a required parameter.

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

(@310) - channel 10 on the module in slot 300.

(@305:310) - channels 05 through 10 on the module in slot 300.

(@202:207,209,302:308) - channels 02 through 07 and 09 on the module in slot 200 and channels 02 through 08 on the module in slot 300.
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	Desired range in ohms: 100Ω (MIN) 1 kΩ 10 kΩ 100 kΩ 1 MΩ 10 MΩ 100 MΩ (MAX)	This is a required parameter.
<ch_list>	Channel List	One or more channels, as shown: (@310) - channel 10 on the module in slot 300. (@305:310) - channels 05 through 10 on the module in slot 300. (@202:207,209,302:308) - channels 02 through 07 and 09 on the module in slot 200 and channels 02 through 08 on the module in slot 300.	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:]RESistance:RANGe:AUTO command).
Because 2-wire and 4-wire resistance are related functions, changing a measurement parameter for one function will also change the corresponding parameter for the other function (see [SENSe:]RESistance:RANGe command).
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.
For 4-wire resistance measurements, the instrument automatically pairs channel n in Bank 1 with channel n+10 in Bank 2 (34901A) or n+8 (34902A) to provide the source and sense connections. For example, make the source connections to the HI and LO terminals on channel 02 in Bank 1 and the sense connections to the HI and LO terminals on channel 12 (34901A) or 10 (34902A) in Bank 2.Specify the paired channel in Bank 1 (source) as the <ch_list> channel (channels in Bank 2 are not allowed in the <ch_list>).
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 returns the range in the form "+1.00000000E+03" for each channel specified. Multiple responses are separated by commas.

Examples

In the following examples, you can susbstitute the node name RES for FRES.

The following command selects the 10 kΩ range on channels 03 and 13 in slot 100. For this 4-wire measurement, the instrument automatically pairs these channels in Bank 1 with the corresponding channels in Bank 2.

FRES:RANG 10E+3,(@103,113)

The following query returns the range selected on channels 03 and 13 in slot 100.

FRES:RANG? (@103,113)

Typical Response: +1.00000000E+04,+1.00000000E+04
