Automatic measurements. More flexibility. Better power quality troubleshooting.



Fluke 1770 Series Three-Phase Power Quality Analyzers eliminate the complexities of power quality logging, troubleshooting, and analysis. Engineered to be the faster, easier way to perform power quality studies, the 1770 Series offers automatic measurements, a straightforward user interface and setup, best-in-class specifications, and a simplified reporting platform. The instrument can also be powered directly from the measurement circuit, eliminating the need to find a power outlet or use a lengthy extension cord.



With the 1770 Series you’ll never miss a critical power quality event—from fast transients up to 8 kV, harmonics up to 30 kHz, dips and swells, as well as the voltage, current, and power measurements that enable you to characterize your electrical system.



Automatic measurement capture



Whether you’re performing a quick system check or a detailed power quality study, consistent data is key. The Fluke 1770 Series offers a unique automatic measurement capture system that helps ensure you’re collecting the right data every time, while still giving you the flexibility to select and adjust specific parameters as needed. More than 500 power quality parameters are captured by default and the guided setup makes it easy to select the right parameters for the system you’re working on. Logged data is instantly viewable, downloadable, and shareable with Fluke Energy Analyze Plus software so you never need to wait to finish a session before reviewing results or analyzing data.



Ultimate measurement confidence



The Fluke 1770 Series are 2-in-1 devices that combine the troubleshooting functionality of a power quality meter with the robust analysis and logging capabilities of a standalone power quality analyzer—in a single, easy-to-use, handheld device.



The ‘PQ Meter’ function gives you immediate access to live onscreen data in the field so you can quickly identify potential problems while troubleshooting. The detailed ‘PQ Logging and Analysis’ function eliminates the complexity of performing power quality studies by guiding you through the setup process ensuring you’re capturing the right data every time. Couple these measurement modes with a unique measurement connection autocorrect function and you can be confident that you never need to worry about going back for a second measurement—even if you were unsure about what to look for when you started.



Powerful analysis software with easy-to-create reports



Fluke 1770 Series Power Quality Analyzers come standard with the powerful Fluke Energy Analyze Plus software, designed to eliminate the hassles found with other multi-purpose application software. Energy Analyze Plus helps you evaluate power quality data right out of the box and without extensive training.



Energy Analyze Plus makes downloading, analyzing, tracking, and reporting power quality and energy data easier than ever. Quickly compare results to historical values, benchmark against industry norms, compare measured data to local conditions, and create a more complete picture of what’s occurring across your facility, even as the data is still being collected. Energy Analyze Plus offers unified support for the Fluke 1730, 1740, and 1770 Series of Energy Loggers and Power Quality Analyzers.

Simplified User Interface and Testing Setup
The 1670 Series takes data management to the next level streamlining test set up and preparation with an advanced bidirectional user interface. When setting up your project, the hierarchical tree topology for clients, sites, distribution boards, circuits, and test points can be easily customized using the high-resolution color touchscreen, or via TruTest™ desktop software. Edit, add, delete, or modify information directly on the tool as you test to ensure accurate data, or transfer updates to your tester via TruTest™ desktop software. Easy-to-read test tables help you quickly see that you are capturing the right measurement data at the right test point, every time. Now you can spend less time setting up your tester and organizing data, giving you more time to perform valuable testing.
Perform All Required Tests up to 30% Faster
Installation testing can be a time-consuming process. It often requires repetitive, manual test setups that can be frustrating and introduce the opportunity for errors.
The Fluke 1670 Series leverages a unique Auto Test function (1673 FC / 1674 FC) that enables you to run through an entire installation test sequence at the touch of a button. An integrated help function provides a visual connection guide to help ensure measurement success. Automatic measurement validation, with user-defined limit warnings, compares test results to the relevant standards and provides you with an immediate visual pass/fail indication to quickly identify potential issues. Eliminating manual testing and automating measurement validation means you can perform your tests up to 30% faster, giving you more time to focus on other critical tasks and increasing your productivity.

* 30% faster testing compared to manual testing.
Reduce Documentation and Reporting Time
The Fluke 1670 Series Multifunction Installation Testers help you reduce documentation time. Link test results to the circuit or point under test, reducing manual data entry and recordkeeping. You can also preview inspection results in the field via the tester and Fluke Connect™ compatibility making it easy to share your data from the field. Fluke TruTest™ Software lets you generate inspection certificates on site with just a few simple steps, so you can finalize and invoice your inspection at the time of service.
Insulation PreTest™ Functionality
The Fluke 1674 FC includes a patented Insulation PreTest™, so you can better protect the installation and avoid costly mistakes. If the tester detects that appliances are connected to the system during the test, it will stop the insulation test and provide a visual and audible warning. This helps eliminate accidental damage to peripheral equipment and saves you both time and money.
Optimized Software and Reporting
Fluke TruTest™ Software simplifies electrical system data management and reporting, eliminating the hassle of traditional data management with a single, integrated Fluke solution. Proper data management and testing information is critical for producing easy-to-understand reports for clients or your management team. TruTest™ streamlines the process by allowing you to create and transfer testing metadata between the software and your installation tester using a USB-C interface cable, or via the Fluke Connect mobile app, which helps you ensure accurate results.
The user-friendly interface, intuitive workflow, and report builder means that you can quickly format your measurement data into printable test certificates and reports, complete with your company logo and electronic signature. The live onscreen dashboard allows you to see the status of all your clients instantly and navigate to further levels of detail if desired.
Fluke TruTest Software allows you to create certificates that are compliant with a growing list of regional reports, including BS7671, DIN VDE 0100-600, ÖVE/ÖNORM E 8101, NIN/NIV, NEN3140, and other European installation test standards. All these reports are available at the touch of a button, and a pre-configured international template ensures that no matter your location, TruTest Software has you covered.
Fluke Connect™ Compatibility
The Fluke Connect™ mobile app allows you to download measurement data from your installation tester for later export to TruTest™ desktop software, allowing for prompt and effective reporting even while on location. Connect additional test tools, like the Fluke 369 FC Leakage Current Clamp or the Fluke 1630-2 FC Earth Ground Clamp to the 1673 FC and 1674 FC to synchronize data between auxiliary devices and test points, providing your clients with a clearer picture of overall facility health.
