This Fluke 1748 Three-Phase Power Quality Logger is in very good cosmetic condition and has been tested and confirmed fully working.

The unit carries a current Fluke factory calibration: calibration date 29 September 2025, due date 29 September 2026 (certificate no. SA01456795).

The rear label option tick-boxes are all unmarked (IEEE 519, Wi-Fi Infrastructure, Remote Monitoring, and upgrade options are not ticked). This is a native 1748 instrument with full 1748-level measurement and event capture functionality enabled as standard.

This item is supplied with a comprehensive accessory kit:
• Fluke 1748 Power Quality Logger (main unit)
• 4x Fluke iFlex 300/24P/IS flexible current probes (24"/60 cm)
• 3-phase and neutral voltage test lead set (flat tangle-free cable with alligator clips)
• 2x sets of blue banana extension leads
• Fluke MA-C8 mains power adapter/connector
• Mains power cable (UK plug)
• USB cable (Mini-USB to USB-A)
• Magnetic hanger kit (strap and magnetic hanger)
• 6x alligator clip adapters
• Accessory bag with spare fuse and miscellaneous hardware
• Soft carry case with shoulder strap

The Fluke 1748 is a high-performance three-phase power quality logger designed for technicians and engineers who need to troubleshoot, quantify energy usage, and analyse power distribution systems with premium accuracy. Fully compliant with IEC 61000-4-30 Class A Edition 3, it simultaneously logs over 500 parameters per averaging period and captures voltage events including dips, swells, and interruptions.

Key features and highlights:
- Logs over 500 different power and power quality parameters for each averaging period
- Event waveform capture and RMS event profile with date, timestamp, and severity information (1748 exclusive)
- Measures harmonics and interharmonics (voltage and current, 2nd to 50th), unbalance, flicker, and rapid voltage changes
- Intelligent 'Verify Connection' function with auto-correction — connection errors indicated by amber power button light
- Powers directly from the measured circuit (100–500 V) or from a wall line cord
- Ethernet and built-in Wi-Fi Hotspot for remote data download and real-time monitoring
- Dual USB ports: one for PC connection, one for direct USB flash drive download without disrupting logging
- IP65-rated ports (Ethernet, USB, AUX, I/O) and IP65-rated iFlex current probes
- More than 20 separate logging sessions storable in the instrument
- Included Fluke Energy Analyze Plus software supports one-touch reporting to EN 50160, IEEE 519, GOST 33073; exports PQDIF and NeQual formats
- Compact form factor designed to fit inside electrical panels
