RECALIBRATION
AFTER
REPAIR
After
any
electrical
component has been
replaced
the
performance
of that
particular
circuit
should
be
checked, as
well
as
the
performance
of
other
closely- related
circuits.
If
necessary
a recalibration
must be
performed. Since the
power
supply
influences
all
circuits,
the
performance
of the entire
instrument should
be
verified
if
work has been done
in
the
power
supply or
if
the transformer
has been
replaced.
If
necessary
a
recalibralion
must be
done.
If
parts
of
the attenuator
circuits
and/or the
Artaiog
AStC
have been
replaced,
It
might
be necessary
to
do Hardware
SCOPE
Calibration
Adjustments. Refer
