Battery tester Rising impedance is a recognised indicator of pending battery failure and using an RE856 as a proactive trending tool allows technicians to monitor the condition of battery cells while they remain connected in a live circuit. A series of results can be logged, downloaded and graphed - providing a guard against any likelihood of failure being attributed to neglect. This ergonomically designed handheld device is a diagnostic tool that comes complete with a clamp meter that integrates to allow further testing and confirmation of current measurements. A major advantage of impedance monitoring over load testing is that batteries are assessed without being discharged. Results stored in the RE856’s memory can be read from its display, downloaded to a PC or issued via an optional printer. Regal Electro Contact info and more items like this at wf.net.au/L294
PXI-based digital multimeters Agilent has introduced two digital multimeters to complement its family of PXI products. The 6.5-digit instruments offer high measurement speeds within their price range, along with good accuracy and stability. The M9182A and M9183A enhanced-performance DMM measure common parameters such as DCV, DCI, ACV, ACI, two- and four-wire resistance and temperature. Each offers 30 parts-per-million basic DCV and 300 parts-per-million basic ACV 1-year accuracies and inputs up to 300 V. The devices deliver 4500 readings/s and 20,000 readings/s. These fast reading speeds translate into higher test system throughput and lower cost of test. The M9183A is capable of additional measurements, such as capacitance. Both DMMs are compatible with PXI, PXI Hybrid and compactPCI instrument mainframes, including the company’s recently announced PXI mainframe products. Each DMM is supplied with a full suite of software to enable easy system integration regardless of what software environment end users have on their PCs. An intuitive software front panel enables DMM set-up, measurement and system troubleshooting without programming. The DMMs include IVI-COM, IVI-C, and LabVIEW G-drivers that are compatible with C++, Visual Basic, NI LabVIEW and many other PC software environments.
