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.
