[SENSe:]{RESistance|FRESistance} Subsystem
This subsystem configures two- and four-wire resistance measurements.
Command Summary
[SENSe:]{RESistance|FRESistance}:NPLC
[SENSe:]{RESistance|FRESistance}:NULL[:STATe]
[SENSe:]{RESistance|FRESistance}:NULL:VALue
[SENSe:]{RESistance|FRESistance}:NULL:VALue:AUTO
[SENSe:]{RESistance|FRESistance}:RANGe
[SENSe:]{RESistance|FRESistance}:RANGe:AUTO
[SENSe:]{RESistance|FRESistance}:RESolution
[SENSe:]RESistance:ZERO:AUTO
[SENSe:]{RESistance|FRESistance}:NPLC {<PLC>|MIN|MAX|DEF}
[SENSe:]{RESistance|FRESistance}:NPLC? [{MIN|MAX|DEF}]
Sets the integration time in number of power line cycles (PLC) for all resistance measurements. Integration time is the
period that the instrument's analog-to-digital (A/D) converter samples the input signal for a measurement. A longer
integration time gives better measurement resolution but slower measurement speed.
This parameter is common to 2-wire and 4-wire resistance measurements. Using the FRESistance version
of this command or query is identical to using the RESistance version.
Parameter Typical Return
{0.02|0.2|1|10|100}, default 10
See Range, Resolution and NPLC for more information.
+1.00000000E+01
Configure 4-wire resistance measurements using a 10 PLC integration time. Then make and read one measurement:
CONF:FRES
FRES:NPLC 10
READ?
Typical Response: +6.27530000E+01
l Only integration times of 1, 10, or 100 PLC provide normal mode (line frequency noise) rejection.
l Setting the integration time also sets the measurement resolution.Resolution Table shows the relationship
between integration time and resolution.
l This parameter is set to its default value after a Factory Reset (*RST) or Instrument Preset (SYSTem:PRESet).
