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.

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.
