Fluke 376 FC
ReviewedPros
- True RMS AC and DC current measurement covers both service work and electronics troubleshooting
- Included iFlex flexible current probe reaches tight panels and large conductors the jaw cannot wrap
- Fluke Connect logging and trend capture let you record intermittent faults over time
Cons
- Premium Fluke price puts it well above capable mid-range clamp meters for occasional home use
- The jaw and iFlex combination makes it bulkier and heavier than a basic clamp meter for tight bags
The Fluke 376 FC is a full featured true RMS clamp meter with a 999.9 A jaw and a bundled iFlex flexible current probe rated to 2500 A AC. It adds Fluke Connect wireless logging, inrush capture, and a CAT III 1000 V / CAT IV 600 V safety rating. This is a professional grade instrument rather than a budget homeowner tool.
Real-World Notes
Based on manufacturer specifications and owner-feedback themes, the 376 FC shines on service calls where a panel is too crowded for a rigid jaw, since the iFlex probe slips around conductors in tight gutters. Owners frequently mention the inrush mode as useful for diagnosing motor starts and compressor faults, and Fluke Connect logging as a way to catch intermittent problems without standing at the panel. The common complaints are price and bulk, not accuracy or durability.

Who Should Consider Something Else
If you only need occasional household voltage checks or basic continuity testing, a lower cost clamp meter or even a quality multimeter will cover your needs for far less money. The 376 FC only pays off if you regularly measure high AC or DC current and will actually use the iFlex probe and wireless logging.
FAQs
Does the Fluke 376 FC measure DC current?
Yes, it measures both AC and DC current through the jaw, which makes it useful for solar, battery, and automotive work as well as standard AC service calls.
What is the iFlex probe used for?
The included iFlex flexible current probe wraps around large or hard to reach conductors and extends AC current measurement up to 2500 A, well beyond the jaw's range.
Is the Fluke 376 FC true RMS?
Yes, it is a true RMS meter, so it gives accurate readings on distorted or non sinusoidal waveforms from drives, inverters, and similar loads.
What safety category is it rated for?
It carries a CAT III 1000 V and CAT IV 600 V rating, which covers most commercial and industrial panel work when used with the proper leads and probes.
Does it work with the Fluke Connect app?
Yes, it supports Fluke Connect, so you can log readings, capture trends, and share data wirelessly from your phone.
Our verdict
The Fluke 376 FC is a serious professional clamp meter with the accuracy, safety rating, and wireless logging that working electricians expect. Its price and size are the main tradeoffs, and casual DIYers will likely be better served by a cheaper clamp meter. For anyone who measures current regularly, it is a justified long term investment.
