mõõtmisel

Mõõtmisel is an Estonian term that denotes the act or process of measuring, typically translated as "during measurement" or "in the act of measuring." It is derived from the verb mõõtma (to measure) and the nominalization mõõtmine, with the suffix -misel forming a form used to indicate the time or manner of measurement. In Estonian, mõõtmisel appears mainly in scientific, technical, and procedural texts to link statements to the phase in which data is collected.

In practice, a measurement process involves selecting an appropriate instrument, ensuring calibration, establishing suitable range and resolution, controlling environmental conditions, performing the measurement, recording results, and assessing uncertainty. The phrase mõõtmisel is used to describe conditions or steps that apply during this phase, for example: "Mõõtmisel kontrolliti kalibreerimisvigu" (During measurement, calibration errors were checked).

Relation to related terms: mõõtmine is the noun for the act of measuring, while mõõtja refers to the person or device that measures, and kalibreerimine means calibration. In formal contexts, measurement results are presented with uncertainty estimates and traceability to standards; mõõtmisel emphasizes the procedural and temporal aspect of obtaining data rather than the numerical outcome alone.

See also conceptually connects to metrology, instrumentation, and quality assurance, where careful attention to procedure and environment during mõõtmisel is essential for reliable measurements.
