Servicing
Information—SC 501
TEST
EQUIPMENT REQUIRED
The
following test equipment and accessories,
or its
equivalent, is
required
for
complete
calibration
of
the
SC
501.
Specifications
given
for
the test
equipment
are
the
minimum
necessary
for accurate
calibration
or
measure-
ment. All test
equipment
is assumed
to
be correctly
calibrated
and operating
with specifications.
If other
test
equipment
is substituted, control settings or
calibration setup may
need
to
be altered to meet
the
requirements of
the
equipment
used.
Detailed
operating
instructions
for the test
equipment used
are not given in
the
adjustment
or
calibration procedures.
Refer
to
the
instruc-
tion manual
for the test
equipment if more
information is
desired.
