Abstract: Systems and methods are provided for measuring electrical parameters in a conductor without requiring a galvanic connection. A device includes a body and a clamp jaw assembly movable between an open position that allows a conductor to be moved into a measurement area, and a closed position that secures the conductor within the measurement area. The clamp jaw assembly includes sensors positioned inside a clamp jaw of the clamp jaw assembly. A user may apply a force to an actuator to move the clamp jaw assembly from the closed position into the open position so that the conductor may be positioned and secured in the measurement area. The clamp jaw assembly includes a visual indicator to guide the user to position the conductor within an optimal region in the measurement area. The clamp jaw assembly is sized and dimensioned to automatically position the conductor within the optimal region during measurements.

Abstract: Imaging tools can be fixedly or removably attached to various surfaces of test and measurement tools. An imaging tool comprising a sensor array capable of receiving electromagnetic radiation from a target scene can be configured to engage a surface of the test and measurement tool such that the imaging tool is supported by the test and measurement tool. When the imaging tool is engaged with the test and measurement tool, the sensor array can be movable relative to the imaging tool so that a target scene viewed by the sensor array of the imaging tool is adjustable without requiring movement of the test and measurement tool.

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: 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.
