Troubleshoot, quantify energy usage and perform quality of service surveys easier than ever
It provides you with fast and easy access to the data you need to make real-time decisions, about critical power quality and energy.
Compact and rugged, this three-phase power quality logger is specifically for technicians and engineers who need the flexibility to troubleshoot, quantify energy usage and analyze power distribution systems. Fully compliant with international power quality standards such as IEC 61000-4-30 and capable of simultaneously logging up to 500 parameters while also capturing events, this unit helps uncover intermittent and hard-to-find power quality issues more easily than ever. It comes equipped with an Energy Analyze plus software which quickly assesses the quality of power at the service entrance, substation, or at the load, according to national and international standards like EN 50160 and IEEE 519.
An optimized user interface, flexible current probes, and an intelligent measurement verification function that allows you to digitally verify and correct connections make setup easier than ever and reduce measurement uncertainty. Minimize your time in potentially hazardous environments and reduce the hassle of suiting up in PPE by using a wireless connection (WiFi) to view data directly in the field.

Easy to use
Designed with the technician in mind, the four current probes are each connected separately allowing flexibility and simplicity. The instrument automatically detects, scales, and powers the probes, so you don't have to worry about ensuring the measurements are correct.
An innovative tangle-free, flat, voltage lead makes connections simple and reliable. The instrument's intelligent ‘Verify Connection' feature, which can be accessed using the PC Setup application automatically checks to make sure the instrument is connected correctly and can digitally correct connections without having to disconnect measurement leads. In the event of a connection error, the power button on the unit will turn from green to amber indicating that the connections should be verified before proceeding.
The logger can also be conveniently and safely powered directly from the measured circuit (up to 500 V). No more searching for power outlets or having to run multiple extension cords to the logging location, which is especially useful when logging at a remote site and when installing inside electrical panels.
Analysis and reporting
Capturing logged data is just one part of the task. Once you have the data, you need to create useful information and reports that can be easily shared and understood by your organization or customers. Fluke Energy Analyze plus software makes that task as simple as possible. With powerful analysis tools and the ability to create customized reports in minutes, you'll be able to communicate your findings and quickly solve problems so you can optimize system reliability and savings. A range of built-in report templates for industry standards such as EN 50160, IEEE 519 and GOST enable one-click reporting so you can create high-quality reports at the touch of a button. Reports can be modified as standards evolve, or new versions become available.
The flexible data views quickly show details of the measurement file in easy to understand formats. The calendar view shown above enables hour/hour, day/day and week/week comparisons simply by selecting the thumbnail views required. Each selected thumbnail is automatically detailed in the lower window.
Advanced data communication and software:
Rugged and reliable
Built to withstand tough working environments, the flexible current probes are IP65 rated and suitable for most installation situations. The optional IP65 voltage adapter ensures safe, reliable operation even in harsh conditions. Standard 6.6' (2 m) leads simplify connection on difficult to access conductors, and optional 16.5' (5 m) leads are useful when installing in difficult locations. With the capability of powering the instruments from the power line up to 500 V, installation is as simple as can be.
Thoughtful design
It includes simple but effective accessories like the MA-C8 adapter making powering the instrument with a line cord easy when not in the field. Ports that aren't always needed in the field are IP65 protected including the Ethernet, USB, AUX and I/O ports protecting for both moisture and dirt ingress. The status LEDs give a quick and clear indication of what the instrument is doing without having to touch any controls. Its compact size means that in most cases it will fit into the available space without any problems.
