Abstract: A positionable holder assembly for an electrostatic discharge plate includes a commercially available photographic-type tripod having a geared lateral arm. A non-conductive plate holder is attached to the lateral arm through a non-conductive intermediate support member so that no conductive material is horizontally closer to the plate than the electronic equipment being tested.

Abstract: An adaptor for use with a magnetic clamp device to ground electrical apparatus to a metallic ground plane. The adaptor has a conductive baseplate and at least one clamp member secured to the baseplate for clamping a ground plate flange of the apparatus to the baseplate. The baseplate has a planar region dimensioned to cooperate with the magnetic clamp device so as to be grounded to the ground plane.

Abstract: A magnetic clamp device which allows the grounding of a conductive flange of test equipment to a metallic ground plane in a quick and efficient manner. The device includes a top plate and a spring-loaded bar secured to the top plate. The bar is straddled by a pair of magnet assemblies so that when the bar is placed over the conductive flange of the test equipment, the magnet assemblies straddle the flange and are magnetically secured to the ground plane, with the spring-loaded bar pressing the flange into conductive engagement with the ground plane.
