Tính năng Ampe kìm Fluke 345:

• 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: 600 V CAT IV power analyzer 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
• Verify batteries: Direct measurement of dc ripple (%) for battery and dc systems
• Troubleshoot harmonics: Analyze 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
• 3-Phase power: Built in capability for balanced loads
• View graphs and generate reports: Use power analyzer with included Power Log software
