NOTE:
Nominal Specs
represent the design specs; all
units should
be
able
to approximate
these-some
will exceed
and some
may drop slightly
below these specs.
Limit Specs represent
the absolute
worst condition
which still might
be considered
acceptable;
in no case
should a unit
perform
to
less than
within any
Limit Spec.
