For the FMMD analysis in table \ref{tab:testaddition} we have two failure modes for its derived component
`no~test~effect' or `reading~out~of~range'.
`no~test~effect' or `open~circuit'.
%~out~of~range'.
The next stage is to combine the two derived components we have made into
a functional group.
\section{FMMD Hierarchy, with milli-volt amp and safety addition}
The next stage is to take the two derived components
and place them into a functional group.
We can now analyse this functional
grou w.r.t the failure modes in the two derived compoennts.
