Fluke 1770; a tool for automatic measurements, greater flexibility, and improved power quality troubleshooting.


Do you suspect an electrical problem but are unsure where it is coming from? This occurs frequently, particularly in large commercial settings. These “mystery disturbances” are disruptions to a process or sensitive equipment operation that do not appear to be caused by any identifiable source of power disturbance but can be identified using a power quality analyzer. It could be ground loops, lightning, high speed transients, or even common mode electrical noise that is the original cause of the problem. If one of these is the problem, you won’t be able to correctly find it without the help of a device. These events occur and vanish in such a short period of time that they cannot be identified without the appropriate tools. Of course, it’s possible that you’re unaware of a problem.  A power quality analyzer may tell you something you didn’t know!


A power quality analyzer is incredibly useful, both commercially and in daily life. You must first understand what a power quality analyzer is before you can learn how to use one to your advantage. It is a device that measures electric power signals to determine the ability of a load to function properly with that power. Why is this so important? Electrical equipment may fail prematurely or malfunction if not supplied with adequate power. This may be costly to you, but that is only the beginning of why it is important to find. A faulty electrical device can be anything from inconvenient to dangerous.


Fluke 1770 Series Product Features:

  • Measurement and automatic recording of important parameters of the network quality (harmonics, voltage dips, voltage increases, asymmetry, inrush current, etc.)
  • Bright, large touchscreen display with physical navigation buttons and an optimized user interface.
  • Guided setup features make setup quick and easy, including the ability to digitally correct test connections automatically without changing the physical probe connections.
  • The ability to set up custom views to quickly get you to the tests and data that matter most to you
  • Flexibility in data transfer (e.g. PC to USB, WLAN, cellular connection, USB direct) without interrupting the analysis of the network quality or energy consumption.
  • Revised software package (Energy Analyze Plus) for modern, intuitive data analysis and reporting.


When performing a quick system check or a detailed power quality study, consistent data is essential. The Fluke 1770 Series includes a one-of-a-kind automatic measurement capture system that helps ensure you collect the right data every time while still allowing you to select and adjust specific parameters as needed. More than 500 power quality parameters are captured by default, and the guided setup makes it simple to select the appropriate 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 have to wait for a session to end before reviewing or analyzing data.


The Fluke 1770 Series is a line of 2-in-1 handheld devices that combine the troubleshooting capabilities of a power quality meter with the robust analysis and logging capabilities of a standalone power quality analyzer.


High-speed voltage transient capture

Transients have a negative impact on otherwise healthy systems and should not be underestimated in their ability to damage your equipment. The consequences of impulsive or oscillatory transients in your system can be disastrous, causing everything from insulation failures to total equipment failures. The Fluke 1775 and 1777 incorporate advanced transient capture technology to assist you in clearly identifying high-speed voltage transients and stopping them in their tracks. The Fluke 1775 Power Quality Analyzer has a 1MHz sampling rate and can capture fast transients, whereas the Fluke 1777 Power Quality Analyzer has a 20MHz sampling rate and can capture the fastest transients in great detail.


Compliant to international standards

The Fluke 1770 Series provides the best-in-class accuracy you’ve come to expect from a Fluke Power Quality Analyzer in a future IEC 61000-4-30 Class A edition 3 compliant package. Furthermore, the 1770 Series has been designed to meet future Class A edition requirements for EN 50160 and IEEE 519 conformance, so you’ll be ready to tackle tomorrow’s measurement requirements today.
