Fluke 345 Power Quality Clamp Meter

END OF LIFE ANNOUNCEMENT The Fluke 345 has not been available since May 2021 due to the discontinuation of key components and supply chain issues. Fluke have worked with suppliers since then but have failed to kind key components. Replacement Products The suggested replacement for this product is the Fluke-125B with AC/DC current measurement clamp. The Fluke 345 is more than an electric power meter. Combining the functions of a clamp meter, oscilloscope, data logger and digital power meter into one handy device, the Fluke 345 is ideal for working with variable frequency motor drives, high efficiency lighting and other loads using switching electronics. With a bright colour display to analyse the harmonic spectrum, a low-pass filter to remove high frequency noise, and a high EMC immunity design, the Fluke 345 is ideal for measurements on switching loads such as variable frequency drives, electronic lighting and UPS systems. Additionally, the Hall Effect measurement system makes measurement of dc current possible without the need to break the circuit, and the internal memory enables longterm logging for analysis of trends or intermittent problems. All voltage, current, power, and harmonic measurements can be logged for minutes, hours, or months. Measurement averaging periods from 1 second to 15 minutes can be selected depending on the application. FEATURES Highest safety rating: 600 V CAT IV. Accurate in noisy environments: Performs even with distorted waveforms present on electronic loads with low-pass filter. Data logging: Identify faults by logging any power quality parameter for minutes, or over a month, including harmonics. Verify batteries: Direct measurement of dc ripple (%) for battery and dc systems. Troubleshoot harmonics: Analyse and log harmonics digitally or graphically. Inrush current: Capture and analyze nuisance tripping, from 3 seconds to 300 seconds. Easy to use: Easily confirm power meter setup with large backlit color display of waveforms and trends. USB download: Download logged data with PowerLog application software. Battery eliminator: powers the instrument when performing extended logging sessions. 3-Phase power: Built in capability for balanced loads. View graphs and generate reports: Use power analyser with included Power Log software.
