Abstract
Abstract A positioning device for test heads, and the like, comprising: an upright stand having legs with leveling mechanisms; a vertically adjustable platform mounted on the stand; two symmetrically arranged pairs of arms mounted on the platform for articulated movement in a horizontal plane; a bracket rotatably mounted to the free end of each arm pair; and, a test head holder tiltably mounted on each bracket for movement about a horizontal axis, a test head being attachable to and between the test head holders, whereby the test head may be vertically, horizontally and tiltably positioned. Clamping devices are provided for locking the test head into place after proper positioning.
