- Reliable tracking of energy consumption profiles for identifying energy-saving opportunities
With Energy Analyse Plus software, you can download, review, and generate automated reports across multiple standards (EN 50160, IEEE 519, GOST 33073). The software supports data exports in formats like PQDIF and NeQual for integration with third-party platforms.
This enables deep, customised analysis of any parameter, from harmonics to voltage fluctuations, across time.
Log with Confidence and Efficiency
The FLUKE 1742 is built with usability and safety in mind, helping users quickly set up, verify, and execute accurate measurements without second-guessing their connections. It features:
✓ Optimised User Interface
A guided, PC-based graphical setup process ensures you capture the right data every time. The intelligent verification feature provides real-time feedback with colour-coded LED indicators: an amber light signals incorrect connections, while green confirms accurate wiring. It‘s the only logger in its class with auto-correction of connection errors.
✓ Rugged Build and Flexible Installation
Its compact design (23 cm x 18 cm x 5.4 cm) and IP65-rated casing make it ideal for tight, harsh environments. Installation is simplified with:
- Tangle-free flat voltage cables
- Slim, flexible current probes
- Magnetic hanger kit (optional accessory) for mounting inside or outside electrical panels
✓ Versatile Power Supply
The FLUKE 1742 operates directly from the measurement circuit (100 V–500 V) or via a wall line cord, giving you full flexibility for testing in virtually any setting.
It includes a lithium-ion battery backup with a 4-hour runtime, ensuring continuous operation during temporary power disruptions.
Smart Connectivity and Storage Options
Stay connected and productive with multiple options for data transfer and setup:
- USB ports (x2): One for connecting to a PC, and the other for direct data download to USB drives
- Wi-Fi and Ethernet: High-speed wireless or wired data transfer
- Field setup support: Easily configure or retrieve logs using a USB cable, Wi-Fi, or Ethernet, even in remote or challenging environments
With these features, you can leave the logger in place while collecting data or changing configurations—saving both time and effort.
1742 Built to Meet the Highest Standards
The FLUKE 1742 Power Quality Logger is compliant with the IEC 61000-4-30 Class A Edition 3 standard, ensuring premium accuracy for all measurement methods. This means you get consistent, reliable, and standardised results—essential for regulatory compliance and high-stakes system evaluation.
It also carries the highest safety rating in the industry:
- 600 V CAT IV / 1000 V CAT III
- Safe for use at the service entrance and downstream installations
