afregelen

Afregelen is a Dutch verb meaning to regulate, tune, or calibrate a device or process by adjusting its control parameters to achieve a specified performance or output. The term is commonly used in engineering, automotive maintenance, process automation, and metrology. It denotes an active adjustment within a feedback or control loop to bring the system’s behavior in line with a reference value, rather than a one-off measurements.

Etymology and scope: The word combines the prefix af- (down or to a target state) with regelen (to regulate). In practice, afregelen can refer to adjusting regulators, electronic setpoints, or mechanical components such as screws and valves. Technicians typically measure outputs—such as speed, pressure, or voltage—and iteratively modify settings until readings fall within tolerance bands. The resulting configuration is usually documented and, if required, certified for traceability.

Relation to related terms: Kalibreren (calibration) determines the accuracy of a measurement system, whereas afregelen concentrates on achieving correct operation of a system through its control mechanism. Afstellen (adjustment) is a broader term for tuning or aligning equipment, of which afregelen is a more specific subtype focused on regulation and control.

Examples: In automotive service, an engine may be afgeregeld to meet emissions and performance specifications. In industrial process control, a PID controller might be afgeregeld to maintain a target process variable. In instrument calibration, the instrument is afgeregeld to ensure its output tracks the reference.
