7. Our advice

7.1 Take the time

Before choosing a periodicity, don't hesitate to spend time analysing the situation of each measuring instrument. The time spent on this analysis should be seen as an investment that will help determine the most appropriate frequency. It should also be borne in mind that not all measuring instruments are required to undergo periodic inspection; for some, regular monitoring can help guarantee measurement quality. This analysis of the situation of each instrument results in a gain in current practice that rapidly recoups the investment in time made.
