The present invention is directed to a system and method for classification of media content based upon user-defined classifications. A ramp support element is rotatably coupled within the vehicle. The relay optics is modular and includes a first module with at least one optical element fixed regardless of the type of equipment and a second module with at least one optical element for which a position is predefined as a function of an angular position of the combiner. The external guidance system sends location signals indicating a location of the implement frame to the operator. The image-capturing module includes image-capturing units facing the object under measurement from different directions or angles. The chemical analyzer is configured to measure chemical concentrations of the plating solution.
