This clamp on meter is a combination power analyzer, power quality logger, and clamp meter, and is ideal for monitoring electronic loads.

The Fluke 345 is more than an electric power meter. Combining the functions of a clamp meter, oscilloscope, data logger and digital power meter into one handy device, the Fluke 345 is ideal for working with variable frequency motor drives, high efficiency lighting and other loads using switching electronics.

One of the leading wattage meters of the world, the multi-faceted Fluke 345 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 the Fluke 345 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.

Besides effectively performing basic tasks like measuring wattage, the Fluke 345 power meters offer the ease of use, portability and flexibility needed to resolve most power issues in commercial, industrial and residential settings.

Setup and troubleshoot variable frequency drives and UPS systems - Verify correct operation by measuring key power quality parameters
Harmonics measurements - Uncover harmonic issues that can damage or disrupt critical equipment
Inrush capture - Check start-up current where spurious resets or nuisance circuit breaker tripping occurs
Load studies - Verify electrical system capacity before adding loads
