:FRESistance
CONFigure:FRESistance [<range>|MIN|MAX|DEF|AUTO
[,<
resolution>|MIN|MAX|DEF]] selects the 4-wire ohms function and allows you to
specify the measurement range and resolution.
Parameters
Comments • To select a standard measurement range, specify range as the input signal’s
maximum expected resistance. The multimeter then selects the correct range
that will accept the input.
• The AUTO or DEFault option for the range parameter enables autorange. The
DEFault option for resolution defaults the integration time to 10 PLC.
• The MIN and MAX parameters select the minimum or maximum values for
range and resolution:
For range:
MIN = 100
Ω
; MAX =100M
Ω
For resolution:
MIN selects the best resolution (the smallest value) for the
selected range.
MAX selects the worst resolution (the largest value) for the
selected range.
• To select autorange, specify DEF for range or do not specify a value for the
range and resolution parameters. In the autorange mode, the multimeter
samples the input signal before each measurement and selects the appropriate
range.
• To specify a MIN or MAX resolution while autoranging, you must
specify the
AUTO or DEFault parameter; CONF:FRES DEF,MIN or
CONF:FRES DEF,MAX or CONF:FRES AUTO,MIN or
CONF:FRES AUTO,MAX (you cannot omit the range parameter). This
prevents the
MIN or MAX resolution from being interpreted as a range setting.
