Instrument
Measuring instrument · Tool
Extended note
An instrument may be physical, technical, linguistic, statistical, or organisational. It does not provide neutral access by itself; calibration, limitation, resolution, categories, and user practice must be documented.
Limitations
Not the same as
- actuality itself
- guarantee of truth
- interpretation-free access

Methodological relevance
