Fluke 345 Power Quality Clamp Meter

The Fluke 345 measures a wide range of electrical parameters for troubleshooting power disturbances in single- and three phase electrical loads. With a bright colour display to see waveforms and trends, 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 speed drives, electronic lighting and UPS systems.

Clamp-on measurement of ac current up to 1400A rms and dc current up to 2000A without breaking the circuit
Low pass filter ensures the clamp meter is accurate in noisy environments even with distorted waveforms present on electronic loads
Identify intermittent faults by logging any power quality parameter for minutes, or over a month, including harmonics
Direct measurement of dc ripple (%) for battery and dc systems
Analyse and log harmonics digitally or graphically
Inrush current measurement to capture and analyse nuisance tripping, from 3 to 300 seconds
Large backlit colour display of waveforms (scope function) and trends
Balanced 3-phase power measurement capability
Power Log software supplied to view graphs and generate reports on a PC
USB interface
Harmonic analysis: Analyse, display and log harmonics up to the 30th harmonic (40th harmonic for 15Hz to 22Hz)
Verify batteries: Direct measurement of dc ripple (%) for battery and dc systems
EN61010 safety rating: 600V CAT IV / 1000V CAT III rated for use at the service entrance
