The autorange setting is queried with the
RESistance:RANGe:AUTO?
information.
Resolution is the smallest change in voltage or resistance that can be
discerned. Assume, for example, a nominal resistance of 10 Ω is measured.
The reading might appear as:
1.084540E+001
If the multimeter is set for 0.976 mΩ resolution, resistance changes as small
as 0.976 mΩ will appear in the measurements.
When setting a resolution, consider the following:
1. Specify a resolution only when making measurements on a fixed
range. Otherwise, the resolution will be changed to correspond to the
range selected during autorange.
2. Resolution affects the reading rate. The better the resolution, the
lower the reading rate.
3. Setting the resolution also sets the aperture time and integration time.
Of these three parameters, the settings of the other two are based on
the one most recently set.
