Product overview: Fluke 376 FC True-RMS AC/DC Clamp Meter with iFlex
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.
Measure:
- 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 AC/DC Clamp Meter with iFlex
Rated 5 out of 5 by Bjlaskey from Good features Professional electrician for over 20 yrs and this is by far the best meter I have owned. The DC mv is great for testing low voltage signals and the flex adapter make it so much safer to get amperage readings inside transformers and cabinets keeping you away from exposed lugs and bus bars. Highly recommend the fluke 376fc.

Rated 5 out of 5 by C Wagner Electric from Very Pleased Very pleased with the meter. The Bluetooth is great, but it's only part of the meter's great features. And I've only begun to play with it.

Rated 4 out of 5 by AmateurHour from Pretty nice rig for the money, BUT... I bought this meter for the sole purpose of remote monitoring a motor current (50'-60' away). It's easy to use; the iOS app and Android app work well for what I'm doing, and allows me to export a .xls file for external analysis. The bluetooth range out of the box is horrible; made it 20' before signal drop out.
Proceed at your own risk. This meter uses a pre-certified bluetooth radio board with a built in chip antenna. I disassembled the meter and removed the chip antenna; replaced it with a piece of solid core 24AWG wire 31mm long (2.4GHz 1/4 wave). Reassembled the meter and now my wireless range is in excess of 150'. Did this on day 1, so no warranty now. Whatever. :)

Rated 5 out of 5 by Anonymous from 376 FC True RMS I’ve used fluke products ever since I started electrician work (25years) ,all have been top notch. The 376 FC is one notch above the top. Best meter on the market for the money and the I flex amp tool makes troubleshooting in tight places much easier and safer.

Rated 4 out of 5 by HoboFist 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 Anonymous 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 5 out of 5 by Victor18 from Dreams come True! I know what I bought! Because I was using this clamp meter for 1 year in my old work location. I received a new fluke clamp meter 381 but I prefer 376 FC. Fluke 376 FC is
- Not to heavy.
- Easier to work with cell phone.
- Good for A/C and D/C.
- True RMS.
- Less Batteries (Only 2 AA).
- Easier to feed between cables.
- Compact and strong tool.

Rated 1 out of 5 by Matt789 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.
