Fluke 1746/15/EUS Power Quality Logger with 60 cm 1,500A iFlex, EUS version

Memory vs sessions vs events (Fluke 1740 series): Internal flash typically stores about 20 logging sessions of 4 weeks at 1-minute intervals. Event capacity (e.g., dips/swells/inrush) is separate from session duration—longer sessions reduce remaining room for high event counts. Warm-up / low-temperature notes follow Fluke operating specs (instrument vs battery limits).

The Fluke 1746/15/EUS Power Quality Logger is a sophisticated instrument designed for engineers and technicians who need to analyze complex electrical networks. This EUS version logger captures detailed power quality data, recording voltage, current, harmonics, and flicker across multiple circuit configurations.
