The "known" is the original calibration of the instrument


Purpose:

To separate the concepts of "calibration" from "control checks"

To clarify that "calibration" is something that happens at the factory, not at time of use by a qualified technician

To clarify that control tests at time of testing are simply a verification (to use the CFS scientist's words) that calibration hasn't changed over time (note Hodgson concept of "over time" in his paper referred to in St-Onge)
