The problem is to take measurements in a metrological context. It
is not sufficient just to read or record a physical quantity from a
suitable apparatus; in addition you must:
– directly or indirectly connect the instruments you use for
references;
– list, check and criticize the working conditions;
– calculate the effect of the influencing quantities; and –
determine the uncertainty of the results.
All these extra actions transform mere measuring into a
“metrological action”.
Once chosen, the instruments have to be implemented, meaning
they have to be set up in a suitable place, away from vibrations,
temperature variations and, generally speaking, protected from any
disruptive “agent”. It is highly desirable to have a large table at one’s
disposal with nothing on it but what is necessary, that is:
