Carries the highest safety rating: 600 V CAT IV rated for use at the service entrance
Delivers accuracy even in noisy environments with distorted waveforms present on electronic loads with low-pass filter
Logs any power quality parameter, has harmonics, for minutes or for over a month to help identify intermittent faults
Verifies batteries with direct measurement of DC ripple (%) for battery and DC systems
Analyzes and logs harmonics digitally or graphically
Captures and analyzes inrush current nuisance tripping due from 3 seconds to 300 seconds
Makes it easy to confirm power meter setup with large backlit color display of waveforms and trends
Downloads logged data via USB with PowerLog application software making it easy to view trends and screenshots, analyze, and create reports
Powers the instrument without using the battery when performing extended logging sessions
Provides built in three-phase power measurement capability for balanced loads
Allows to view graphs and generate reports with Power Log software

Combining the functions of a clamp meter, oscilloscope, data logger and digital power meter into one handy device, It is ideal for working with variable frequency motor drives, high efficiency lighting and other loads using switching electronics.

The multi-faceted is packed with features such as a bright, color display to analyze the harmonic spectrum, a low-pass filter to remove high frequency noise and a high EMC immunity design, making this power analyzer ideal for troubleshooting power quality on switching loads. The internal memory of this electric power meter enables long-term power quality logging for analysis of trends or intermittent problems. Additionally, the Hall Effect clamp meter design makes measurement of dc current possible without the need to break the circuit.
