Hello,
your idea sounds good and handles the exception on teardown as well.

I will now provide each of the instruments with an explicit shutdown()
method which frees the interface card as well.
These methods will be called in a finally

Different objects in this class represent laboratory equipment, which
might raise an exception (e.g. overtemperature).
In any case the equipment has to be switched off after the experiment,
since if a
