Abstract: Test and measurement systems can include a test and measurement tool configured to generate measurement data representative of at least one parameter of an object under test and an imaging tool configured to generate image data representative of a target scene. The imaging tool can be removably attachable to the test and measurement tool. The test and measurement system can include a communication link that can provide communication between the test and measurement tool and the imaging tool. The communication link can facilitate one or both of communication of image data to the test and measurement tool and measurement data to the imaging tool. Systems can include a display in communication with at least one of the test and measurement tool or the imaging tool for presenting at least one of image data or measurement data to a user.

Abstract: Systems include a test and measurement tool configured to acquire measurement data representative of at least one parameter of a device under test, an imaging tool configured to acquire image data representative of a target scene, and a display device. The display device can include a display and can be in communication with the test and measurement tool and the imaging tool. The display device can receive measurement data from the test and measurement tool and image data from the imaging tool, and present a display representative of at least one of the measurement data and the image data on the display.

Abstract: A system and method for analyzing a device that includes a mass configured for motion. The system includes a tri-axial accelerometer disposed to detect acceleration vectors of the device and to output three channels of acceleration data, and a user interface receiving the three channels of acceleration data. The user interface is configured to correlate the three channels of acceleration data with a reference frame defined by three orthogonal axes intersecting at a vertex, and includes a display and a selector. The display shows sets of options that represent dispositions of the device with respect to gravity, placements of the tri-axial accelerometer with respect to the device, and orientations of the tri-axial accelerometer with respect to the device. The selector selects one device disposition option, one tri-axial accelerometer placement option, and one tri-axial accelerometer orientation option.

Abstract: A multimeter includes a case having a rotary selector knob for selecting a multimeter function. A circuit board defining multiple switching terminals thereon is located in the case. A rotary switch assembly is operatively coupled to the selector knob. The rotary switch assembly has a plurality of contact pairs which selectively complete a galvanic connection across predetermined pairs of switching terminals. The rotary switch assembly further includes first and second switch members located in opposition on respective sides of the circuit board. Each of the switch members has at least one of the contact pair.

Abstract: A multimeter comprises a housing structure including a case defining an interior cavity in which components of the multimeter are located. The case has a shell of rigid polymeric material defining at least one groove containing a softer polymeric material. In addition, the housing structure further includes at least one rigid panel element juxtaposed to the case. The panel element has an elongate bead on an inside surface thereof in alignment with the groove such that the elongate bead presses into the softer polymeric material to provide a seal.

Abstract: A multimeter for testing a plurality of electrical parameters comprises a case having a plurality of test lead jacks. Each of the test lead jacks includes a unitary conductive socket. Preferably, the sockets are made of metal such as brass. A circuit board located in the case has jack conductors in electrical communication with each of the sockets. A jack detection arrangement is adapted to automatically determine whether a plug is inserted into a respective one of the sockets based on a change in electrical characteristics. For example, the jack detection arrangement may include a photonic emitter and a photonic detector situated such that a beam path therebetween is interrupted by insertion of a plug. The case may further have a rotary selector knob for selecting a multimeter function.
