Syntax [SENSe:]FRESistance:RESolution {<resolution>|MIN|MAX}[,(@<ch_list>)]
[SENSe:]FRESistance:RESolution? [{(@<ch_list>)|MIN|MAX}]
[SENSe:]RESistance:RESolution {<resolution>|MIN|MAX}[,(@<ch_list>)]

Description Set or query the resolution of the 2-wire or 4-wire resistance measurements on the
specified channels.
Parameters
Name
Type
Range
Default
<resolution> Numeric
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>
<ch_list>
Channel
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.
If the parameter
is omitted, this
command will be
applied to the
whole scan list.
Explanation  MC3164 and MC3264 do not support the 4-wire resistance measurement function.
 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 use MIN or MAX to set <resolution>. Wherein, MIN selects the smallest
resolution; MAX selects the largest resolution.
 <resolution> is related to the current integration time and range (<range>). The
relations are as shown in the table below.
Integration time
Resolution (ppm range)
0.02PLC
3ppm× <range> (MAX)
0.2PLC
0.7ppm× <range>
1PLC
0.3ppm× <range> (DEF)
2PLC
0.2ppm× <range>
10PLC
0.1ppm× <range>
20PLC
0.06ppm× <range>
100PLC
0.035ppm× <range>
200PLC
0.03ppm× <range> (MIN)
 When the range is set to autoranging, an error will be generated when <resolution> is
set to a numeric value (except MIN and MAX).
 The instrument sets the resolution to 0.3ppm× <range> after a Factory Reset (send
