säätäntö

Säätäntö is a Finnish noun that denotes the act or process of adjusting, tuning, or regulating something. The word is formed from säätö (adjustment, regulation) and the suffix -ntö, which indicates a process or state. In many technical contexts, säätäntö describes the ongoing work of setting parameters to achieve a desired performance.

In control engineering and automation, säätäntö refers to the tuning of a control loop, including setting gains, time constants and filters to obtain stability and a suitable response. It is commonly discussed in terms such as säätäntöprosessi (the tuning process) or säätäntöarvo (the setpoint or reference value).

Outside technical fields, säätäntö can also refer to adjusting settings on devices, software, or systems—such as a computer, home automation, or consumer electronics—where the user carries out fine adjustments to meet preferences or requirements.

Säätäntö is related to, but distinct from, säätö (the act of adjustment) and asetus (the specific setting or parameter). In legal or normative language, more common terms are säädös or asetus rather than säätäntö. The usage is principally found in Finnish technical and professional contexts.
