Säätökaarteista

Säätökaarteista refers to reference charts or cards used in various technical and industrial settings to guide the adjustment of equipment parameters. They function as compact guidance tools that encode standard or recommended values, curves, or procedures intended to achieve reliable and repeatable operating performance.

The term is formed from säätö, meaning adjustment or regulation, and kaarti (kaartti, card or chart) in Finnish, with the plural possessive form säätökaarteista. In practice, säätökaarteista can be found in both physical card formats and digital equivalents, depending on the era and the equipment involved.

Typical content found on säätökaarteista includes parameter ranges, preset gain or sensitivity values for controllers, offsets for sensors, valve position references, or calibration curves. They may present these data as tables, graphs, or step-by-step procedures. In automation and process control, such charts often relate to tuning or configuration tasks, for example guiding the adjustment of PID controller parameters, and they can be specific to a machine, device model, or process condition.

Creation and maintenance of säätökaarteista are usually the responsibility of equipment manufacturers or process engineers. Charts should reflect current hardware capabilities and process requirements; outdated cards can lead to suboptimal performance or safety concerns. Users are expected to verify applicability to their specific setup and to supplement charts with on-site measurements or supervisor guidance when necessary.

Related concepts include calibration sheets, configuration guides, and parameter libraries. See also scaling charts and process control documentation for further context.
