Abstract: A handle for an electronic instrument housing includes an elongated grip portion. The grip portion includes two elongated elements each having opposed ends. The elements are connected to each other to form an elongated chamber. An elastomeric layer encompasses an intermediate portion of the grip portion, and the grip portion has a vent aperture communicating with the chamber. The vent aperture may be beyond the elastomeric layer, at one or both ends. One of the elongated elements may form a channel with tapered edge surfaces receiving the other element, so that pressure of elastomeric molding tends to wedge the parts together to form a seal against incursion of the elastomer.

Abstract: A simplified user interface for an electronic test and measurement device comprises an arrangement of a segmented LCD device and a plurality of keys used to implement a softkey system, in combination with a single AMPs input connector and a rotary selector having only a single position for each basic kind of parameter to be measured. The segmented LCD device includes, at each location adjacent to a key, a plurality of segments representing a vertically-arranged list of functions to be controlled. In one embodiment of the invention, the housing of the electronic test and measurement device is fabricated to have finger-like projections overlaying a portion of the LCD screen for creating the appearance of the continuation of displayed LCD softkey separation lines.
