ABSTRACT:
A test probe having only two substantially rigid electrically conducting members which are insulated from each other, these members terminating in respective contact portions. When the probe is in use, these two contact portions simultaneously contact spaced apart areas of a current conducting segment then being tested. An insulated handle is formed by a protecting layer of insulation coupled to the two conducting members; and a pair of conducting leads pass through the handle and are electrically connected to the respective conducting members. In a preferred embodiment, the two conducting members are constituted by a cylindrical shaft which is longitudinally bisected into separate longitudinal portions that are bonded to each other by a layer of insulating adhesive. The cylindrical shaft terminates in a conical contact tip which also is longitudinally bisected, the two bisected portions of this tip constituting the contact portions of the probe.
