Fluke 345 Power Quality Clamp Meter The ideal meter to troubleshoot modern electrical loads
Recommended Accessories
The Fluke 345 is more than just a power meter; it combines 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. • AC/DC current: Clamp-on measurement of AC current up to 1400 A RMS and DC current up to 2000 A without breaking the circuit • Highest safety rating: CAT IV 600 V power analyser is rated for use at the service entrance • Accurate in noisy environments: Clamp meter performs even with distorted waveforms present on electronic loads with low-pass filter • Data logging: Identify intermittent faults by logging any power quality parameter for minutes, or over a month, including harmonics • Troubleshoot harmonics: Analyse and log harmonics digitally or graphically • Inrush current: Capture and analyse nuisance tripping from 3 seconds to 300 seconds • View graphs and generate reports: Use power analyser with included Power Log software • Three phase power: Built-in capability for balanced loads • Verify batteries: Direct measurement of DC ripple (%) for battery and DC systems • One year warranty
