Abstract: An assembly for transferring data comprises a measurement data acquisition unit in the form of a portable measuring device, a measurement data processing unit, and an auxiliary unit for transferring data between the acquisition unit and the processing unit. Contact-less coupling elements are operatively associated with the acquisition and auxiliary units respectively for transferring measurement data between the acquisition unit and the auxiliary unit by contact-less coupling. Data are transferred between the auxiliary unit and the processing unit. The auxiliary unit includes a connecting member for mechanically detachably connecting the auxiliary unit with the acquisition unit such that the contact-less coupling elements face one another at a predetermined spacing and such that the connected acquisition and auxiliary units together form a portable measuring device.

Abstract: In multimeters having a plurality of input connections there is a danger of the measuring conductors being incorrectly connected in such a manner that the setting of the measurement range switch does not correspond to the input connections to which contact is made. In order to avoid damage which may be caused by making an incorrect contact to the input connections, an electrically and/or mechanically acting disabling device is coupled to the measurement range switch for permitting a disabling of particular input connections. The disabling is carried out in such a manner that contact can always only be made to that input connection for receiving a test signal through the measuring conductors, to which a measurable variable is assigned that corresponds to the measurable variable set with the measurement range switch.

Abstract: A housing for a portable measuring instrument includes inherently stable supporting housing parts formed of hard plastic, the supporting housing parts including a front and a back with relatively long right and left sides, relatively short sides and two opposite outer edges, an operating surface on the front, a display on the front, and operating elements on the front; and a flexible, frame-like shock protector in the form of two side parts formed of soft plastic integrated in the housing, the side parts protruding beyond all of the sides of the supporting housing parts and extending at the right and left sides between the front and back, the side parts being permanently secured to the housing parts, and beads each being disposed at a respective one of the outer edges of the front, for protecting the front including the display and the operating elements, the beads protruding along the long sides beyond the front defining a recessed grip along with the operating surface, for accommodating the thumb of an oper

Abstract: A measuring device housing includes two mutually assembled housing shells having mutually engaged dust protection edges, a trowel shape with a relatively narrow handle-type holder part changing into a relatively wide plate-type indicator part, an operating surface having sides, a switching wheel operating element mounted on the operating surface and extending beyond one of the sides thereof, and another operating element disposed on the operating surface laterally of the switching wheel, the operating elements being disposed within the swinging range of a thumb of the right hand of an operator of the measuring device gripping the holder part from behind for actuating the operating elements.

Abstract: Portable measuring device, including a measuring instrument, a carrying strap fastened to the measuring instrument for hanging the measuring instrument around the neck, measuring lines electrically connected to the measuring instrument and passing through at least part of the carrying strap, measuring probes connected to the measuring lines, the measuring lines being in the form of flexible spiral cables between the carrying strap and the measuring probes, and at least one mounting disposed on the measuring instrument for fastening unused measuring probes hanging on the measuring lines.

Abstract: Multi-purpose measuring device with a tilting display which includes a display assembly with a housing for visually indicating a measured value of a variable to be analyzed, an auxiliary assembly with another housing separate from the display assembly housing for performing measurements, a hinge interconnecting the housings permitting relative tilting of the housings in two directions into different planes at an angle relative to each other and into a common plane, and a carrying strap fastened in vicinity of the hinge, the auxiliary assembly having dimensions and weight in proportion to the display assembly causing the center of gravity of the measuring device to lie in vicinity of the auxiliary assembly and causing the auxiliary assembly to hang downward from the carrying strap with the display assembly disposed above the auxiliary assembly.

Abstract: Portable multimeter, including an indicating subassembly for visualizing a measured value of a measuring variable to be examined, a processing subassembly for converting or adapting the measuring variable, separate housings for the subassemblies being connected to each other and having edges about which the housings are swingable for folding together into a rest position, control and indicating parts to be protected being disposed toward the inside of the housings in the rest position, a bead disposed in the vicinity of the edges forming a hinge and increasing the useful interior space of the housings, the hinge including at least one interacting hinge element being integral with each housing and rotatably connecting the housings together.
