Fluke's 345 Power Quality Clamp Meter combines the features of a clamp meter, oscilloscope, data logger and digital power meter
Combining the functions of a clamp meter, oscilloscope, data logger and digital power meter, the Fluke 345 Power Quality Clamp Meter is designed for working with variable frequency motor drives, high efficiency lighting and other loads using switching electronics. The Fluke 345 features a color display to analyze the harmonic spectrum, a low-pass filter to remove high frequency noise and a high EMC immunity design. The meter's internal memory is designed to enable long-term power quality logging for analysis of trends or intermittent problems. The Hall Effect clamp meter design makes measurement of DC current possible without the need to break the circuit.
