%%% NOT sure I should leave this in
FC4: presents an interesting dilemma.
The {\fm}, Pt100:VAL\_ERR, could cause an out of range error, but may
cause an incorrect temperature reading.
An out of range error, has less consequences than an incorrect reading, because
an out of range error is detectable.
Because FMMD forces the analyst to choose only one symptom to tie the {\fm} to,
the worst, or most dangerous possible
symptom must be chosen.
