The Fluke 345 Single-Phase Power Quality Clamp Meter is ideal for commissioning and troubleshooting modern electrical loads. With a bright color display to analyze the harmonic spectrum, a low-pass filter to remove high frequency noise, and a high EMC immunity design, the 345 is ideal for measurements on switching loads such as variable frequency drives, electronic lighting and UPS systems. Additionally, the Hall Effect measurement system makes measurement of DC current possible without the need to break the circuit; its internal memory enables long-term logging for analysis of trends or intermittent problems.
