International Classification:

G01R 31/02

US Classification:

324 725

Abstract:

The invention provides a non-contact voltage detector (“NCVD”) that includes a housing, a power switch, and an LED flashlight. The housing includes an upper portion and a lower portion which are slidably attachable to one another. A voltage sense circuit is positioned within the housing and illuminates a voltage sense indicator when it detects an AC voltage. The power switch is operable to activate the voltage sense circuit and the LED flashlight. The NCVD includes a first set of rails and a second set of rails for slidably attaching the NCVD to a test and measurement device, such as a digital multimeter (“DMM”) or an infrared (“IR”) temperature gun.

International Classification:

G01R 1/20

US Classification:

324126, 324127, 173170

Abstract:

In another embodiment, the invention provides a clamp meter configured to receive a removable and rechargeable battery pack. The clamp meter includes a main body having a first axis, a handle, a clamp, a trigger, and a display. The handle has a second axis and includes a first recess configured to receive the battery pack. The first recess includes at least first and second electrical terminals which are exposed when the battery pack is not inserted into the first recess. The second axis forms an oblique angle with the first axis, and the battery pack is inserted into the first recess along the second axis. The clamp is coupled to the main body, aligned with the first axis, and operable to measure an electrical characteristic of a conductor based on an induced current. The trigger is operable to selectively open and close the clamp, and the display configured to display an indication of the electrical characteristic.

US Classification:

374133, 374208, 374E01001

Abstract:

The invention relates to an infrared (“IR”) thermometer that includes a pistol-grip handle which is operable to receive a high-voltage removable and rechargeable battery pack. In one embodiment, the thermometer includes a main body, a handle portion, a trigger, a display, a control section, an LED flashlight, a plurality of sensors, and a high-voltage removable and rechargeable battery pack. The handle forms an oblique angle with respect to the main body and includes a first recess for receiving the battery pack. The trigger is operable to initiate a temperature measurement, and the display is operable to display, among other things, a measured temperature. The plurality of sensors include, for example, an IR temperature sensor, a thermocouple, a humidity sensor, and an ambient temperature sensor.

G01R 19/00

US Classification:

324 67

Abstract:

Embodiments of the invention relate to a wall scanner that includes a housing, a plurality of sensors, a display, and a control section. The housing includes a handle portion and a body portion. The handle portion is adapted to receive a removable and rechargeable battery pack such as a high-voltage lithium-ion (“Li-Ion”) battery pack. The body portion of the housing encloses the plurality of sensing devices, such as, for example, capacitive plate sensors for sensing the presence of a stud behind a surface, a D-coil sensor for identifying the presence of metal behind the surface, and a non-contact voltage sensor for detecting the presence of live wires carrying AC currents. The display is configured to display, among other things, the location of an object behind the surface in real-time, the depth of an object behind the surface, and whether an object behind the surface is ferrous or non-ferrous. The control section includes a plurality of actuation devices for controlling the functions and operations of the wall scanner, such as the scanning mode.

International Classification:

G01R 31/44

US Classification:

324414

Abstract:

A combination lighting tester tool. The combination lighting tester tool includes at least three independent testing tools for identifying and diagnosing a problem in a lighting system. For example, the tester includes a lamp testing function in which a high voltage test signal is generated and transmitted using an antenna. When the test signal is in proximity to a gas filled lamp, the voltage is of sufficient magnitude to ionize the gas inside the lamp, causing the lamp to illuminate. The tester also includes a ballast testing function in which the power lines or wires connecting a ballast to a lamp or lighting fixture are tested, and a filament tester for testing the filaments in a lamp for continuity or resistance. The tester also includes a worklight for illuminating an area under test and one or more display devices (e.g., LEDs, an LCD display, or the like) which provide an indication of, for example, a test being performed or a result of a test.

International Classification:

G01R 1/04

US Classification:

324126

Abstract:

Clamp meter with detachable clamp and a clamp storage area. The clamp meter includes a clamp and a housing. The clamp includes a measurement end and a handle portion. The measurement end includes a first measurement portion and a second measurement portion. The handle portion includes a first handle and a second handle. The housing includes a recess configured to removably receive the clamp when the clamp is not in use. The housing is connected to the clamp via a cord. When the clamp is received in the recess, the first measurement portion and the second measurement portion are positioned completely within the recess, the first handle and the second handle extend at least partially from the recess, and the recess prevents the clamp from being used. The clamp is capable of being removed from the recess in a one-handed use position.
