Abstract
A method of calibrating a monitoring device () for monitoring movement of a movable component () of an elevator system () comprises detecting () a travel time (Δt) between a starting time (t) and a stopping time (t') as well as acceleration (a(t)) of at least one movement of the movable component (); determining () a travel distance of the movable component () by integrating the detected acceleration (a(t)) twice with respect to the detected travel time (Δt); correlating () the determined travel distance (s) with the detected travel time (Δt) to form a pair of travel time and travel distance; and storing () the pair of travel time and travel distance (Δt,s) as part of a travel profile ().
