To select a standard measurement range, specify range as the input signal’s maximum expected resistance. The multimeter then selects the correct range.

FRESistance:RANGe

[SENSe:]FRESistance:RANGe <range> selects the range for 4-wire resistance measurements.

Parameters


Parameter Name	Parameter Type	Range of Values	Default Units

<range>	numeric	100Ω1kΩ10kΩ100kΩ1MΩ	ohms
		10MΩ100MΩMINMAX

Comments •

•MIN selects the minimum range available with the FRESistance:RANGe command: 100 Ω. MAX selects the maximum range available: 100 ΜΩ.

•You must select a range using FRESistance:RANGe before specifying resolution.

•Specifying a fixed range disables the autorange mode set by the

FRES:RANG:AUTO command.

•The FRES:RANG command overrides the range setting from a previous CONFigure command on the same function. The multimeter uses the same aperture time to set the resolution on the new range as was selected by

CONFigure.

•*RST Condition: FRES:RANG 1kΩ (1E+03)

Example Set Four-Wire Resistance Range to 10MΩ

FRES:RANG 1E+07

4-wire resistance range is 10MΩ.

FRESistance:RANGe?

[SENSe:]FRESistance:RANGe? [MINMAX] returns one of the following numbers to the output buffer:

•The present resistance range selected if MIN or MAX is not specified.

•The minimum resistance range available (100Ω) if MIN is specified.

•The maximum resistance range available (100MΩ) if MAX is specified.

Example Query the Measurement Range

FRES:RANG 100	Select 100Ω range.
FRES:RANG?	Query multimeter to return the present range.
enter statement	Enter value into computer.
