The Fluke 376 FC True-rms Clamp Meter with iFlex is the most advanced troubleshooting tool for industrial and commercial electricians. The 376 is part of the Fluke Connect family of wireless test tools that enable you to log, trend and monitor measurements while remaining safely away from the arc flash zone through Bluetooth connectivity.

Find the cause of difficult problems

The 376 FC clamp meter uses an integrated low-pass filter for accurate measurements of non-linear signals, such as adjustable speed drives, electronic ballasts and other non-linear loads. The clamp also uses proprietary inrush measurement technology to filter out noise and capture motor starting current exactly as the circuit protection sees it.


  • Voltage to 1000 V AC or DC
  • Resistance to 60 kΩ with continuity detection
  • Min, max, average, and inrush recording to capture variations automatically
  • 500 mV DC measurement range to interface with other accessories
  • 1000 μF capacitance measurement

Work safely and conveniently

The 376 FC clamp carries a CAT III 1000 V, CAT IV 600 V safety rating, designed to offer you the highest possible protection in a test tool.

The included iFlex flexible current probe provides easier access to large conductors in tight spaces. The flexible probe:

  • Expands the measurement range to 2500 A AC
  • Allows frequency measurement to 500 Hz with body jaw and iFlex

Reviews: Fluke 376 FC True-RMS Clamp Meter

Rated 4 out of 5 by from Great daily carry meter. But ex-381 owners beware TLDR: Great general purpose meter, will fill just about everything you need for a meter 90% of the time. BUT be leery about coming to this from the older Fluke 381, all the specs are the same...but the wireless functionality is much worse (Use: Industrial Electrician) I bought this meter to replace my Fluke 381. I had been using the 381 for years as a general multimeter and loved it. It gives you just about everything you need for daily driving it as your carry matter, and having BOTH AC & DC up to 1000 amp on the clamp is a sweet bonus. The one issue I had was that whenever I got a service call to troubleshoot an unknown issue that would have a surprise capacitive circuit(because the customer had no clue). this was an issue because the 381 does not have a capacitance test setting, so I would have to go back out through the facility to get my megger which has the setting in it. Seeing as how this 376FC has the exact reading specifications as the 381, plus the capacitance and mV additions, I figured it was a great buy. Overall it is, the meter works great and is almost as handy as the 381. The reason I give it 4 stars is because the Bluetooth is just terrible, and doesn't get you very far before it cuts out. I used to use the 381's removable display a lot, very handy for troubleshooting by yourself, I was hoping the Fluke Connect app could replace that function and make it an even trade off....it very much does not. If you have direct line of sight it will go about 30'-35', HOWEVER if you don't have L.O.S (like when it is in a closed cabinet as advertised, or when you are troubleshooting controls from elsewhere on a line) you loose connectivity at about 8-10'. That is rubbish, my ear buds stay connected 90' L.O.S and 45' through concrete walls and machinery....they should put a better BT version in this. Unfortunately it also doesn't come close to the 381's removable display distance either as I had no issues through obstacles with that either at 30-40' (assuming it was a lower frequency radio?). That is also separate from the functionality of the less than stellar fluke connect app itself. So sadly, even though this is newer than the available Fluke 381, and has more measurement features...the wireless does not live up to the 381's practically, and makes me wish they would refresh that with stronger/better radios and more measurements.

Rated 1 out of 5 by from Dont waste your money. This meter may work ok standalone. I bought it specifically for the fluke connect app. Doesnt work with my phone. No compatibility chart on web page. This thing is borderline paperweight.

Rated 1 out of 5 by from very limited usefulness of the WiFi feature 1) for the WiFi feature to work, one has to log into a Fluke account, that is the meter does not connect to the phone app without a Fluke account. 2) the WiFi connection on the Fluke is flaky. When turning WiFi on, it should show up on the phone WiFi, but it does not. On the 376 FC, the WiFi symbol turns on, but no signal is detected by the phone or nearby PCs. At one point it had worked but that is no longer the case. We don't use it very often and I was particularly excited about the WiFi feature. It could be nice if it were reliable.

Rated 2 out of 5 by from Very disappointed with wild phantom readings. Fluke is a name in the testing industry that mostly goes unquestioned. I recently decided to upgrade my fluke meter after 7 years of service, That old meter still functions so well people ask me what it is and where to get one. With our company growing so should the quality and capibility of the equipment. I cannot express how disappointed i am with this new meter. The capability is there but the quality is disturbing, I have not even put this meter into service yet and in its current condition it will never seen in the field use. While not probing anything i am reciving false/ phntom readings between 0.5A to 15A DC. Do i have a faulty unit or have i just purchased o $500 tic tester?

Rated 5 out of 5 by from Blown Away! This meter is the by far the greatest meter I have ever owned. I do HVAC and Electrical and it works great for both. 10/10 recommend to other techs out there! Thanks fluke

Rated 4 out of 5 by from Stability of Fluke Connect Mobile Software Both iOS & Android version of Fluke Connect are quite unstable for retreiving the data with time-stamp. Most of the cases, the time-stamp were incorrect. However it works fine when downloaded to the PC. This should be a program bug and would like to know how soon could Fluke solve it?

Rated 5 out of 5 by from Great Meter I just bought this meter and it works great, I do have a question I use the wire leads on the unit all the time and was wandering if fluke makes some kind of snap on lead holder or a rubber slip on holder to hold the leads on that you can buy as a accessory for a meter like this?
