Measurement Configuration
This section contains information to help you configure the multimeter
for making measurements. You may never have to change any of the
measurement parameters discussed here, but they are provided to give
you the flexibility you might need.
AC Signal Filter
The multimeter uses three different ac filters which enable you to either
optimize low frequency accuracy or achieve faster ac settling times.
The multimeter selects the slow, medium, or fast filter based on the
input frequency that you specify.
Applies to ac voltage and ac current measurements only.
• The ac filter selection is stored in volatile memory; the multimeter
selects the medium filter (20 Hz) when power has been off or after a
remote interface reset.
• Front-Panel Operation: Select from the menu the slow filter (3 Hz),
medium filter (20 Hz), or fast filter (200 Hz). The default is the
medium filter.

• Remote Interface Operation: Specify the lowest frequency expected in
the input signal. The multimeter selects the appropriate filter based
on the frequency you specify (see table above). The CONFigure and
MEASure? commands select the 20 Hz filter.
