Incorporated into the CFL510G is an auto set-up feature that determines the impedance of the cable under test, sets the instrument accordingly and selects the optimum gain and pulse width chosen by the operator. A large, high-resolution backlit display comes standard, and the unit features four output impedances, and a velocity factor between 0.20 and 0.99. The IP54-rated CFL510G is lightweight, powered by AA batteries and comes standard with a three-year warranty.
April 2, 2013 - Ideal Industries—a manufacturer and supplier of tools, connectors and testing products for the electrical and datacom trades—introduced its next-generation SureTrace circuit tracer, which helps electricians locate wires or cables behind walls, pinpoint opens/shorts, and identify fuses and breakers on both energized and de-energized circuits from 0-600V AC/DC. SureTrace circuit tracers have four defined ranges that allow you to select the proper sensitivity for a specific job. Rather than blinking lights and beeps, its display provides a numeric value between 0 and 99, and a variable pitch/tone audible indication as fast-response tracing feedback, while its peak detector instantaneously registers signal strength. Another time-saving advantage, says Ideal, is that handset signal communication is tuned tighter to reduce false signalling on noisy circuits.

February 19, 2013 - Circuit Breaker Analyzer claims it has introduced the world’s first app for iPhone capable of capturing vibration signatures from working circuit breakers to provide quantifiable data for computerized maintenance management systems (CMMS) and other preventive maintenance programs. Using the accelerometer inside every iPhone or new model iPod, the app captures vibration data in all three axes, as well as across time, at sample rates of 100Hz to 400Hz, depending on the version. Both sample rates provide ample data, says the company, for a detailed vibration signature for later analysis of potential mechanical faults inside the circuit breaker. By comparing the newly acquired vibration signature to a database of known good profiles, and/or the vibration signature of the breaker’s ‘first trip’ operation, pattern recognition algorithms can determine when changes in the ‘envelope’ or shape of the vibration signature indicate a hidden mechanical problem.
