Test & Measurement
October 10, 2013 - Extech Instruments’ MA430 Series of digital clamp meters (MA430 400A AC, MA430T True RMS AC and MA435T True RMS AC/DC) are compact and easy to hold, says the company, while offering a 1.2-in. jaw opening to accommodate conductors up to 350MCM.
October 7, 2013 - The new FLIR DM93 digital multimeter promises to help technicians obtain accurate readings on VFD-controlled equipment.
(UPDATED September 11, 2013, with cool VIDEO) August 29, 2013 - Klein Tools says it has introduced its MM500 auto ranging multimeter in response to increasing requests from professionals for meters that stand up to real-world environments. The tool is suitable for verifying or troubleshooting electrical circuits, and features a sealed IP67 dust and waterproof rated case with 3 m/10 ft. drop protection and CAT IV (600V) safety rating. Measuring up to 750V AC and DC, MM500 boasts a user-friendly three-button functionality, detects AC or DC voltage automatically, and includes both visual and audible continuity indicators. Auto-Hold automatically locks readings on the display when measuring in hard to access areas.
August 9, 2013 - Megger has developed a new series of insulation and continuity testers that conform to IEC1010-1 standards. Rated to CAT IV 600 V, the MIT400 series boasts greater user safety when testing in higher voltage environments and suitable for use in high energy systems throughout the electrical, power and telecommunications industries. The series, which includes the MIT400, MIT410, MIT415, MIT420, MIT430 and MIT40X, offers a measurement range from 20 GΩ to 200 GΩ and features adjustable insulation test voltages from 250V to 1000V and 50V to 1000V. The testers take DC voltage measurements, as well as TRMS measurements, for data monitoring on noisy lines.
July 23, 2013 - When a voltage problem is suspected as a cause of equipment failure, Ideal Industries suggests using its VPM voltage performance monitor, which works at the point where equipment is connected. The VPM offers real-time monitoring of TRMS voltage, frequency and harmonics. Once plugged into an outlet, it will measure, categorize and list each voltage event, including its magnitude, duration and exact time of occurrence. With this information, the technician can identify whether voltage is the cause of the equipment failure or some other issue exists. Up to 512 events can be logged onto the VPM for analysis. The VPM can also be used to determine whether voltage is stable enough to connect additional equipment to a circuit, or if power conditioners—such as a UPS or surge protector—are required.
July 23, 2013 - T3 Innovation is now shipping its dual-mode Arc Chaser cable tester and TDR, which is capable of finding faults (e.g. opens, shorts, arc faults) on energized cables up to 600V up to 12,000 feet. It can monitor live cables for intermittent conditions, capturing these events and reporting where and when they occur. Using Spread Spectrum Time Domain Reflectometry (SSTDR), Arc Chaser promises accuracy to better than 1%. Arc Chaser features a colour, touchscreen that displays results in graphical or text format, and saves reports saves reports that can be transferred to PCs. The unit self-calibrates, says T3, and provides imperial or metric measurements.
July 9, 2013 - Megger now offers four “enhanced” 4-terminal earth/ground resistance and soil resistivity testers promising greater testing flexibility: the DET4 series. The DET4TC2 and DET4TCR2 include ART (attached rod technique) capability that is already included in Megger’s DET3TC, as well as stakeless (clamp-on) testing for applications where traditional fall-of-potential testing is not possible. ART testing allows onsite grounds to be tested separately without having to remove the utility connection. Stakeless testing allows the operator to use the instrument like a clamp-on ground tester in applications where that method is viable, while also being able to operate a fall-of- potential tester when necessary. All four models offer selectable output voltage of 25V and 50V, and are rated to 100V Cat IV. DET4TC2 and DET4TCR2 have a resistance measurement range up to 200,000 ohms, while the DET4TD2 and DET4TR2 have a resistance measurement range up to 20,000 ohms. All of the units are IP54-rated and are designed to meet safety standards.
June 20, 2013 - EA Technology has launched an instrument for identifying defects in live cables of distribution voltages. The CableData Collector tests for Partial Discharge (PD) activity in live cables by measuring radio frequency currents. It works with most types of single and three phase insulated cables at distribution voltages, up to several miles/kilometres in length. Information about PD activity is recorded by the CableData Collector hardware and can be sent to EA Technology for analysis. Alternatively, users can buy EA Technology’s software package to perform their own data analysis.
June 20, 2013 - Introducing Test Results Manager 2.0, a comprehensive analysis and reporting software from AFL, designed for use with Noyes fiber optic test and inspection products. TRM 2.0 Basic is included with every Noyes OTDR and OPM5 test sets and additional copies are available for purchase. TRM 2.0 Advanced adds powerful new automatic bi-directional analysis and macrobend detection capabilities, says AFL. Both versions support industry standard GR-196 v1.1 and SR-4731 Issue 1 and 2 OTDR files and permit fiber inspection images from the Noyes Focis inspection system to be included in test reports.
June 19, 2013 - Fluke Networks says its new family of Versiv cable certification testers will allow data communications installers to more quickly, accurately and profitably achieve system acceptance for copper and fiber jobs. Versiv is a powerful platform offering interchangeable modules for copper, fiber and Optical Time Domain Reflectometer (OTDR) testing, as well as new software innovations that speed test time and accuracy, and simplify testing setup, planning and reporting, Fluke says.
June 19, 2013 - Fluke Corporation with Hart Communications introduce the Fluke 709H Precision Current Loop Calibrator, a tool with a user-friendly interface and Hart capabilities that reduces the time it takes to measure or source, voltage or current, and power up a loop, says Fluke. It features a built-in, selectable 250-ohm resistor to tune the loop for Hart Communications. The 709H and non-HART 709 models also offer an interface with dedicated buttons, a Quick-Set rotary encoder knob, and two wire connection for measurements.
June 12, 2013 - Greenlee Communications has launched the 500XP Pair Tracing Probe with acAlert hazardous AC voltage detection. The 500XP is designed to help cable technicians trace wires when installing, servicing, and maintaining voice, data and video (VDV) services. The acAlert feature emits audible and visible alerts when brought near wires and cables that contain harmful levels of AC voltage. Updated electronics also reduce unit power consumption and increase battery life, says Greenlee.
