The functionality of the devices and the associated higher complexity increase with each generation of devices. At the same time users‘ expertise is dwindling. The willingness to keep the number of experienced employees available is decreasing. When new positions are filled, there is a growing gap in experience in dealing with the various devices.
Probably the strongest requirement to the measuring devices is the security of their availability, ideally paired with an early warning if there is a need for interaction with the devices or even for service calls. It can be assumed that the devices operate within the limits (or better) permitted by calibration law.
