[SENSe:]FRESistance:NPLC
[SENSe:]RESistance:NPLC
Syntax [SENSe:]FRESistance:NPLC {<PLCs>|MIN|MAX}[,(@<ch_list>)]
[SENSe:]FRESistance:NPLC? [{(@<ch_list>)|MIN|MAX}]
[SENSe:]RESistance:NPLC {<PLCs>|MIN|MAX}[,(@<ch_list>)]
[SENSe:]RESistance:NPLC? [{(@<ch_list>)|MIN|MAX}]
Description Set or query the integration time via the power line cycles mode for the 2-wire or 4-wire
resistance measurements on the specified channels.
Parameters
Name
Type
Range of Values
Default Value
<PLCs> Numeric
Any numeric value between MIN and MAX.
The final integration time is decided by the
“
Principle of setting with greater value”.
The standard values of the range:
{0.02|0.2|1|2|10|20|100|200}
Wherein: MIN=0.02PLC, MAX=200PLC.
1PLC
<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.
 The longer the integration time is, the slower the measurement speed and the better
the measurement resolution will be; the shorter the integration time is, the faster the
measurement speed and the lower the measurement resolution will be.
 You can also set the integration time via the aperture time mode (send the
[SENSe:]RESistance:APERture or [SENSe:]FRESistance:APERture command).
 The instrument sets the integration time to 1 PLC after a Factory Reset (send the
*RST
command). An Instrument Preset (send the
SYSTem:PRESet command) or Card Reset
(send the
SYSTem:CPON command) does not affect the current integration time
parameter.
Return
Format
The query returns the integration time in scientific notation for each channel specified.
Multiple return values are separated by commas.
Example FRES:NPLC 0.2,(@103,113)
FRES:NPLC? (@103,113)
The query returns +2.00000000E-01,+2.00000000E-01.
You can replace FRES with RES to set or query the integration time for the 2-wire resistance
measurements on the specified channels.
