nollaus

Nollaus is a Finnish term meaning the act of returning something to zero or establishing a zero reference. Derived from the word nolla (zero) with the agentive suffix -us, it is widely used in technical and everyday language to describe calibration, offset correction, or resetting procedures that create a baseline for subsequent measurements or operations.

In metrology and instrumentation, nollaus refers to zeroing a measurement device to remove drift or offset. Common examples include taring a weighing scale (setting zero with an empty container) and zeroing electronic instruments such as voltmeters or digital readouts before taking measurements. The goal is to ensure accuracy by starting from a known reference point.

In manufacturing and engineering, nollaus is used to recalibrate equipment to define a machine’s or process’s zero point. For instance, a CNC machine or robotic system may undergo nollaus to establish the origin of coordinates prior to production runs, ensuring consistent and repeatable results.

In everyday and consumer contexts, the term can describe a reset or calibration step in devices or software, often performed to restore normal operation after errors or drift.
