Abstract

A calibration device for calibrating a motor for providing a substantially constant airflow in a ventilation system is disclosed. In one embodiment, a calibration device (664) includes an adjusting module configured to adjust an electric current supplied to a motor until a monitored airflow rate reaches a target value; a determining module configured to determine a difference between values of the electric current before and after adjusting; and a communication module configured to cause to store, in a memory of the motor or ventilation system, the difference as one of adjustment values corresponding to one of a plurality of predetermined rotational speed ranges of the motor.
