PHY.9:4.6 - Obtain a first result and revise the physical arrangement

Work one admissible preparation through to a predicted readout and an interpreted result. This can reveal an unresolved physical relation before an instrument is built. It also gives collaborators a concrete construction to implement or compare.

Change a condition that could defeat the intended use. Check the shared premise of a subtraction, the range of an inverse, the time available for a response or the disturbance caused by the probe. Return to the smallest implicated part of the arrangement.

Use available observations where they can change confidence or selection. C.11.DUA helps choose between another measurement, a conditional result and proceeding with uncertainty. A statistical comparison or a calibration certificate does not substitute for a missing physical response.

Return the proposed arrangement, its preparation and readout, the result it supports and the conditions that would change that use. The next work may be implementation, calibration, inference or a different measuring interaction. PHY.10 constructs a physical test when the purpose is to separate rival accounts.
