OPTIONS:
This box lists at least one way of getting the answer
to the question. When there is more than one way
to get the answer, the different options will be
given. Usually the easiest or best option is first.
REASON FOR
QUESTION:
If you know why the question is being asked, it
should be easier to understand
the diagnostic logic
and easier to answer the question. This is
especially helpful when a measurement
is just
a
little bad. Knowing why the question is being asked
should help you decide if the answer should be
YES or NO.

that doesn’t work. DO NOT USE THIS BOX TO PICK A JUMP-IN
POINT. ALWAYS
RUN A COMPLETE
CHAIN WHEN
INSTRUCTED
TO DC SO.
