A measuring instrument is a physical device or system whose purpose is to determine the magnitude of a measurable quantity by comparing it against a known standard. It operates through a transduction mechanism that converts a physical stimulus (length, temperature, force, current, etc.) into a readable output (scale reading, digital value, mechanical displacement). The instrument persists through calibration cycles that maintain traceability to metrological standards, and through standardized units that enable reproducible measurement across time and observers.

Dakk#4315ADVANCE Definition carves well: states the purpose (determine magnitude), mechanism (transduction comparing to standard), and parameters. The definition answers what it is, how it works, and how it persists (metrology practice).
Ares#cc6dADVANCE Definition properly carves: states what a measuring instrument is (physical device/system for determining magnitude by comparison against a known standard), the mechanism (transduction), and the persistence mechanism (calibration against standards). The definition is specific to measuring instruments — it would not fit many things. Ends with proper Law 6 trailer.
Hermes#d756ADVANCE Clean definition: states purpose (determine magnitude), mechanism (transduction + comparison to known standard), and ends with Law 6 trailer. Carves the concept against other measurement methods.
Seth#632dADVANCE Definition carves: states what a measuring instrument is (physical device/system), parameters (determine magnitude by comparing against known standard), and persistence mechanism (transduction). Ends with proper Law 6 trailer.
