- EUS Version
Hardware Features
- Measure all three voltage and current phases plus the neutral current: Three-phase and neutral voltage leads and four flexible current probes
- Comprehensive logging: More than 20 separate logging sessions can be stored in the instrument. A comprehensive range of power and power quality variables are automatically logged so you never lose measurement trends
- Measure with premium accuracy: Meets the rigorous IEC 61000-4-30 Class A Edition 3 standard for Testing and measurement techniques–Power quality measurement methods
- Capture dips, swells and interruptions: The 1748 includes event waveform capture and RMS event profile, along with date, timestamp and severity information to help pinpoint potential root causes of power quality issues
- Measure key power quality parameters: Measures harmonics and interharmonics for voltage and current, also includes unbalance, flicker and rapid voltage changes
- Optimized user interface: Capture the right data every time with quick, guided, graphical PC based application setup and reduce uncertainty about your connections with an intelligent verification feature and the only auto-correction function for a power quality logger. Connection errors are automatically indicated via an amber light on the units power button which turns green once corrected
- Optimized user interface: Quick, guided, graphical setup ensures you're capturing the right data every time, and the intelligent verification function indicates correct connections have been made, reducing user uncertainty
- Flexible power supply: Powers directly from the measured circuit with the widest available range for a power quality logger automatically going from 100 V to 500 V or from a wall line cord, so you can test anywhere
- Rugged and reliable: Designed to withstand harsh installation environments with IP65 rating when used with IP65 voltage input adapter
- Two external USB ports: One for PC connection and another for quick, simple data download to standard USB thumb drives, or other USB devices, allowing you to leave the measurement device in place without disrupting logging
- Ethernet connectivity: Wired and wireless connections for instrument setup and high-speed data download
- Compact size: Designed to fit in tight spaces and panels with small 23 cm x 18 cm x 5.4 cm (9.1 in x 7.1 in x 2.1 in) footprint
- Highest safety rating in the industry: 600 V CAT IV/1000 V CAT III rated for use at the service entrance and downstream
- Optimized measurement accessories: Unique tangle-free flat voltage cable and thin flexible current probes ensure easy installation even in tight spaces
- Battery life: Four-hour operating time (backup time) per charge on lithium-ion battery to withstand temporary power disruptions
- Security: Safeguard your best asset from theft with a standard chain or other security device
- Magnetic hanger kit: Conveniently stow the instrument safely inside or outside of electrical panels; compatible with all models and included with 1748 model as standard
Software Features
- "In-workshop" or "in-the-field" setup and download through PC application software: simple download using USB memory stick, WiFi download, wired ethernet connection or via USB cable
- Energy Analyze plus application software: Download and analyze every measured detail of energy consumption and power quality state-of-health with automated reporting
- One-touch reporting: Create standardized reports according to commonly used standards like EN 50160, IEEE 519, GOST 33073 or export data in PQDIF or NeQual compatible format for use with third party software
- Advanced analysis: Choose any available logged parameter to create a highly customized view of logged measurements for advanced correlation of data
