is
presented
in Table 4-7.
Use
the
recommended
resistor
decade
(see
Table
4-1)
to
apply
the
prescribed
re-
sistances
to
the Vf2
INPUT
terminals
and,
where
required,

AC
Volts
Calibration
4-32.
The
calibration
procedure
for the ACV
FUNCTION
of the
8600A is
presented
in
Table
4-8.
Use the
recommend-
ed ac
voltage
calibrator
(see
Table
4-1)
to
apply the
pre-
scribed
ac voltages
at
the
indicated
frequencies
to

INPUT
terminals and,
where
required,
make
the
adjustments
to
meet the
specified
display
limits.
