Key Features:

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 finalise 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 no matter
your location, TruTest Software has you covered.

Fluke Connect:

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’ll
be able to 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
