The Fluke 1748 is the flagship model in Fluke's 1740 Series of three-phase power quality loggers, fully compliant with IEC 61000-4-30 Class A Edition 3 — the most rigorous international standard for power quality measurement. Designed for technicians and engineers who need to troubleshoot, quantify energy usage, and analyse power distribution systems, it logs over 500 parameters simultaneously while also capturing events such as dips, swells, interruptions, and transients. Used with the included Fluke Energy Analyze Plus software, it delivers one-touch standardised reporting to EN 50160, IEEE 519, and GOST 33073, making compliance reporting straightforward.
