  • Measuring instrument for testing voltage
    Patent number: 9188604
    Abstract: A measuring instrument, in particular a voltage tester, is provided having two probes which are arranged in separate housings through which connecting cables extend. The housings are magnetically attractive, because of either a first magnet arranged on a first one of the housings for cooperation with the magnetic material of the other housing, or a corresponding pair of opposed magnets provided in magnetically attractive relation on the two housings, respectively. Recesses are provided in the second housing opposite the corresponding magnets of the first housing. Corresponding pivot ribs extend circumferentially around the housings in the space between the first one magnet and the adjacent probe end, thereby to permit accurate spacing of the probes during the taking of a test measurement.
