Change
the input voltage
and
the
setting
of
chanrtet
B according
to table
4.2
and check
that the
amplitude
of
the
signal
agrees
wi^
the value
fisted
.
Use
the
setect/adjust
keys
to select
each
step
number.
NOTE:
The
AC
voltages
listed
in this
are peak-ta-peak
voltages
(sine

The
values
listed
between
brackets
()
are
the
RMS
values
that
have
to
be chosen on
the
Fluke
