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.
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
