correct functioning as well as their “metrological”
performances. This procedure testifies the status of
each instrument and particularly if their metrological
performances remained within acceptable limits for the
service they are supposed to do.

The “calibration” operation consists in a comparison
between the indications given by the instrument under
test against that of a reference instrument of a higher
accuracy class.
All readings are then processed according to a
recognized procedure.

That’s all!
The basic difference between a "common" calibration
procedure and a calibration executed by a SIT Center
is that the SIT center ensures the traceability of the
measurements, which are made using reference
instruments approved and constantly monitored by the
national metrological bodies (in our case IMGC). At the
