INTEGRATION TIME

Where measurement results are affected by noise, it is advantageous to use a
longer integration time.
5.4

RANGE/AUTORANGE

The use of auto-ranging may lead to ranging transients. Using a fixed range
avoids this problem and the time penalty incurred in range searching. However,
you must be sure to select a range that is suited to the experiment to be run.
5.5

MAINS HARMONICS

There may be measurement interference at mains frequency, and harmonics of the
mains frequency. This is a natural consequence of the ac supply frequency and is
not a cause for concern. To some extent, these disturbances can be avoided by
choosing sweep frequencies that do not coincide with the power supply frequency
or its harmonics, by the use of increased integration time, by better screening of
the sample under test, or a combination of all of these.
