[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 (34460A/61A)
0.02, 0.06, 0.2, 1, 10, 100. Default: 10 (34465A/70A without
DIG option)
0.001, 0.002, 0.006, 0.02, 0.06, .2, 1, 10, 100. Default: 10
(34465A/70A with DIG option)

l Selecting an integration time in power line cycles overrides an aperture set with the [SENSe:]
{RESistance|FRESistance}:APERture command.
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 rela-
tionship between integration time and resolution.
l This parameter is set to its default value after a Factory Reset (*RST) or Instrument Preset
(SYSTem:PRESet).
