Personal Greeting

The Fluke 1670 Series Multifunction Installation Testers will revolutionize the way you work. With an ergonomic design, seamless user interface, integrated data management capabilities, wireless connectivity (1673 FC and 1674 FC), and comprehensive reporting software, the 1670 Series sets the new standard for an integrated installation testing solution.

Reliable installation testing is essential for ensuring the safety, optimal functionality, and integrity of a facility’s electrical systems. The 1670 Series' rugged design allows you to verify the safety of electrical installations in domestic, commercial, and industrial applications while meeting the requirements of IEC/HD 60364-6 and all relevant local installation test standards.

With the 1670 Series, you’ll be able to perform your required testing faster and reduce the time you spend on documentation, all while having the ultimate confidence in the data you’re collecting.

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, a smart device, or by PC. Edit, add, delete, or modify information directly on the tool as you test to ensure accurate data, or transfer updates to your tester via the Fluke Connect™️ mobile app or 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 up to 50%

The Fluke 1670 Series Multifunction Installation Testers help you reduce documentation time by up to 50%. 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, a smart device, or PC, and Fluke Connect compatibility making it easy to store, manage, and 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. The Fluke Connect mobile app enables you to document and input all relevant photos and inspection notes, so you can complete your work on site, eliminating extra work at the office.

* 50% faster reporting and documentation based on customer interviews.

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 TruTest Software has you covered no matter your location.

Fluke Connect Compatibility

Enhance the functionality of the 1673 FC and 1674FC Installation Testers with the Fluke Connect mobile app, eliminating tedious data entry and optimizing data management with cloud storage. The Fluke Connect mobile app wirelessly synchronizes measurement data from your installation tester for later export to TruTest desktop software, allowing for prompt and effective reporting even on location. Use the Fluke Connect app to create projects and upload them to your 1673 FC and 1674 FC for streamlined data management. Construct distribution boards and circuits to send to your tester, using this data to guide your testing regime. With the Fluke Connect app, you can also take photos with your smart device and assign them, along with notes, to specific test points or assets, creating detailed visual inspection reports.

With the powerful Fluke Connect ecosystem of test tools, you can take your troubleshooting and reporting to the next level. Connect additional test tools, like the Fluke 369 FC Leakage Current Clamp or the Fluke 1630-2 FC Earth Ground Clamp, to synchronize data between auxiliary devices and test points, providing your clients a clearer picture of overall facility health.
