6. Our advice

6.1 Choose the right C2I perimeter

The selection of measuring equipment is of paramount importance. Take the trouble to do it carefully. In addition to the measurement range or technology, you can consider the resolution, brand or range (in the sense of quality) of the instrument. Indeed, when comparing equipment with too different resolutions and/or ranges, the possible anomaly of the "best" instrument runs the risk of being masked by the noise (variance) produced by "low-end" instruments.
