    1) The surface of a measuring wheel is subject to wear. This depends on contact pressure, acceleration behavior in the application, traversing speed, measurement surface, mechanical alignment of the measuring wheel, temperature, and ambient conditions. We recommend you regularly check the condition of the measuring wheel and replace as required.2) No permanent operation. Decreasing signal quality.3) When measured from the top of the measuring surface.4) One cycle corresponds to an upward and downward movement of ? 3 mm from the recommended pretension position.5) When mounted from below, the encoder weight during spring pretensioning must be taken into account.
