Abstract
An apparatus capable of testing a displacement transducer having an extendable portion includes a slide capable of being moved along an axis and a measuring unit capable of determining a displacement of the slide along the axis. The extendable portion is connectible to the slide so that, when the extendible portion is connected and the slide is moved, the extendable portion is extended and retracted along a path. A method capable of testing a displacement transducer includes determining electrical signal values outputted from the transducer corresponding to displacements of the transducer and creating a statistical model based upon the electrical signal values and the displacements of the transducer. The method further includes determining a displacement error for each of the electrical signal values and the displacements of the transducer based upon the statistical model. Displacement errors that exceed a predetermined tolerance are determined.
