Description Configure the specified channels for the 2-wire or 4-wire resistance measurement functions
with the specified range and resolution, start a scan and read the readings.
Parameters
Name
Type
Range
Default
<range> Numeric
Any numeric value between MIN and MAX.
The final range is decided by the “
Principle of
setting with greater value
”.
The standard values of the range:
{200Ω|2kΩ|20kΩ|200kΩ|1MΩ|10MΩ|100MΩ}
Wherein: MIN=200Ω, MAX=100MΩ,
DEF=AUTO
AUTO
<resolution> Numeric
Can receive any numeric value between
0.03ppm×<range> and 3ppm×<range> The
final resolution is decided by the “
Principle of
setting with smaller value
”.
The standard values of the resolution: refer to
the “Explanation”.
0.3ppm×
<range>
<scan_list>
Scan
List
One or more channels (only for the
multiplexer channels), the rules are as
follows:
(@101) :channel 01 on the module in Slot1;
(@101:103): channel 01 through 03 on the
module in Slot1;
(@101:103,301): channel 01 through 03 on
the module in Slot1 and channel 01 on the
module in Slot3;
None
Explanation  For MC3164 and MC3264, the 4-wire resistance measurement function is not
supported.
 These commands are equivalent to the
CONFigure:RESistance or
CONFigure:FRESistance command followed by the READ? command.
 For the 4-wire resistance measurement function, channel n is paired with channel
n+16 (MC3132 and MC3232, wherein the range of n is from 1 to 16) or n+10 (MC3324
and MC3120, wherein the range of n is from 1 to 10) automatically. Channel n is used
to connect the source terminal of the DMM and channel n+16 or channel n+10 is used
to connect the sense terminal of the DMM. The paired channels cannot be configured.
 You can select autoranging to allow the instrument to automatically select a proper
measurement range or you can select a fixed range to set the range manually.
 Autoranging rule: for signals under test that is between 10%*Range and
110%*Range, the instrument automatically selects Range as the current range.
 When <range> is set to DEF or AUTO, an error will be generated if <resolution> is set
to a numeric value, because the instrument cannot calculate the integration time
accurately (especially when the input signal is continuously changing) when the
autoranging is combined with a numeric resolution. If your application requires
autoranging, be sure to specify "DEF" for <resolution> or omit the parameter.
