Real-World Scenarios

In one scenario, we used the 1673FC to test a problematic GFCI in a commercial kitchen that was nuisance-tripping. The tester’s advanced RCD analysis showed the trip time was within spec but the trip current was borderline, helping us pinpoint a faulty appliance. During EV charger installation verification, the dedicated test mode simplified the process significantly, displaying pass/fail results for each test leg. The wireless connectivity was a game-changer for our reporting workflow.

Claims vs. Reality

Fluke claims the 1673FC “revolutionizes the way you work.” While that sounds like marketing hyperbole, after extensive use, we found it to be true for our workflow. The time savings from auto tests and wireless reporting were substantial. The only gap we noticed was that the on-screen instructions for advanced tests (like EV charging station configuration) could be more detailed for a first-time user.
