Remarks
This command affects both 2-wire and 4-wire resistance measurements. All
FRES and RES commands affect the equivalent settings for all resistance
measurements.
Setting the resolution with this command changes any aperture set with
the [SENSe:]RESistance:APERture command.
For the <resolution> parameter, you can substitute MIN or MAX for a
numeric value. MIN selects the smallest value accepted, which gives the
highest resolution; MAX selects the largest value accepted, which gives the
least resolution.
To achieve normal mode (line frequency noise) rejection, use a resolution
that corresponds to an integration time that is an integral number of
power line cycles (see table below). Specify a resolution of 0.3 ppm x
Range (which corresponds to 1 PLC) or better to ensure normal mode
rejection.
The instrument sets the resolution to 1 PLC after a Factory Reset (*RST
command) or an Instrument Preset (SYSTem:PRESet command).
