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.
