Ohms
Calibration
4-30.
The
calibration
procedure
for
the
Kf2
function of
the
8600A
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,
make
the adjustments
to
meet
the
specified display
limits.
CAUTION!
Remove
any
applied voltage
from
the
8600A
input terminals before
starting the
Ohms
Calibration.
4-31.
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 the
VS2
INPUT
terminals and, where
required,
make
the adjustments
to
meet
the
specified display
limits.

The
following information
is
provided to
assist in
locating malfunctions
in
the
8600A.
It is
recommended
that the theory of operation
in
Section 3 be
read
com-
pletely before attempting to troubleshoot the instrument.
