More visibility, reduced uncertainty and better power quality and energy consumption decisions

Compatible with the Fluke Connect® mobile app and desktop software, this unit provides you the data required for you to make critical power quality and energy decisions in real-time. Ideal for conducting energy studies and basic power quality logging, this automatically captures and logs over 500 power quality parameters, giving you more visibility into the data you need to optimize system reliability and savings.

Features an optimized user interface and an intelligent measurement verification function that enables you to decrease measurement errors by digitally verifying and correcting common connection errors makes setup easier and reduces measurement uncertainty. Access and share data remotely with your team via the Fluke Connect® app so you can maintain safer working distances and make critical decisions in real-time, reducing the need for protective equipment, site visits, and check-ins. You can also quickly and easily chart and graph measurements to help identify issues and create detailed reports with the included Energy Analyze Plus software package.

Features

  • Measure all three phases and neutral with 4 flexible current probes (sold separately)
  • Comprehensive logging: More than 20 separate logging sessions can be stored on the instruments. In fact, all measured values are automatically logged so you never loose measurement trends. They can even be reviewed during logging sessions and before downloading for real-time analysis
  • Capture dips, swells, and inrush currents: includes event waveform snapshot and high resolution RMS profile, along with date, timestamp and severity to help pinpoint potential root causes of power quality issues
  • Bright, color touch screen: Perform convenient in-the-field analysis and data checks with full graphical display
  • Optimized user interface: Capture the right data every time with quick, guided, graphical setup and reduce uncertainty about your connections with the intelligent verification function
  • Fully integrated logging:Connect other Fluke Connect devices to this product to simultaneously log up to two other measurement parameters
  • Energy Analyze Plus application software:Download and analyze every detail of energy consumption and power quality state of health with our automated reporting
  • Present data locally on the logger, on the Fluke Connect mobile app and desktop software, or through your facility’s Wi-Fi infrastructure
  • Power the instrument directly from the measured circuit
  • Review measured values during logging sessions and before downloading for real-time analysis

Easy to use

The four current probes are connected separately; the instrument automatically detects and scales the probes. The thin current probes are designed to easily get through tight conductor spacing and are easily set to 150 or 1500 A for high accuracy in nearly any application. An innovative tangle-free flat voltage lead makes connection simple and reliable and the instrument’s intelligent ‘Verify Connection’ feature automatically checks to make sure the instrument is connected correctly and can digitally correct common connection issues without having to disconnect measurement leads.

The detachable power supply can be conveniently and safely powered directly from the measured circuit—no more searching for power outlets or having to run multiple extension cords to the logging location.

Data downloading couldn’t be easier or more flexible:

  • Download directly to a USB flash drive that plugs directly into the USB port of the instrument
  • View measurements remotely via the Fluke Connect mobile app and desktop software, helping you maintain safer working distances and reducing the need for personal protective equipment and unnecessary site visits and check-ins

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.

Applications

Load studies: verify electrical system capacity before adding loads

Energy assessments: quantify energy consumption before, and after improvements, to justify energy saving devices

Harmonics measurements: uncover harmonic issues that can damage or disrupt critical equipment

Voltage and current event capture: monitor for dips, swells and inrush currents that cause false resets or nuisance circuit breaker tripping

Log the most common parameters

Designed to measure the most critical three-phase power parameters, this instrument can simultaneously log RMS voltage, RMS current, voltage, current events, and current THD, voltage and current harmonics up to the 50th harmonic, active power, reactive power, power factor, active energy, reactive energy, and more. With enough memory for more than a year of data logging, this power logger can uncover intermittent or hard-to-find issues that might otherwise have been missed.

Webinar: Introduction to Portable Precision Power Analyzers with Fluke


This wideband precision analyzer is accurate enough for the lab, yet it's built for the field. Offering you more freedom than ever before to make high accuracy power measurements wherever you need to. Whether in the lab, or in the field. Designed for portability and eliminates the need to carry large, fragile, expensive analyzers into the field, allowing you to make measurements directly at the load in nearly any environment. By measuring directly at the load, you can discover how the equipment operates under real-world conditions, with real-world variables, not just at a test bench or in the lab.
During our 1-hour webinar, we've covered:
- The new Fluke Norma 6000 Power Analyzer for accurate measurements at frequencies from DC to 500kHz.
- It is not a Power Quality Analyzer.
- It is a Power Analyzer for accurate measurements at frequencies from DC to 500kHz.
- It is designed to be used in the field, its rugged, battery-operated, lightweight, and suited to use outside of a laboratory environment.
- You’ll learn why it can help you, where and how it is used.

The Fluke Energy Analyze Plus Desktop Software lets you download data straight to a USB or via a direct USB to your desktop. You can then upload your data to your profile and access your data entries anywhere; even on your mobile device!

Webinar: Introduction to Portable Precision Power Analyzers with Fluke


This wideband precision analyzer is accurate enough for the lab, yet it's built for the field. Offering you more freedom than ever before to make high accuracy power measurements wherever you need to. Whether in the lab, or in the field. Designed for portability and eliminates the need to carry large, fragile, expensive analyzers into the field, allowing you to make measurements directly at the load in nearly any environment. By measuring directly at the load, you can discover how the equipment operates under real-world conditions, with real-world variables, not just at a test bench or in the lab.
During our 1-hour webinar, we've covered:
- The new Fluke Norma 6000 Power Analyzer for accurate measurements at frequencies from DC to 500kHz.
- It is not a Power Quality Analyzer.
- It is a Power Analyzer for accurate measurements at frequencies from DC to 500kHz.
- It is designed to be used in the field, its rugged, battery-operated, lightweight, and suited to use outside of a laboratory environment.
- You’ll learn why it can help you, where and how it is used.
