Features

  • Measure voltage and current with your clamp jaw
  • Faster, safer testing - all without touching a live wire - using FieldSense technology
  • Complete 3-phase voltage and current tests with fewer steps
  • Power quality indicator shows whether equipment or power line is faulty (378 FC)

Description

The Fluke 378 FC is a true-rms clamp meter that use FieldSense™ technology to make testing faster and safer, all without touching a live conductor. You get accurate voltage and current measurements through the clamp jaw. Simply clip the black test lead to any electrical ground, put the clamp jaw around the conductor and see reliable, accurate voltage and current values on the display. The 378 FC clamp meter also includes a unique PQ function that will detect and display power quality issues, relating to current, voltage, power factor or any combination of the three.

    • Good but Not Perfect
Received a later version with minor difference in the bag. It has a strap in the middle of the stretchy strings. Took some time to figure out the value of Fluke 378 FC. This awesome meter is about Speed and Convenience in taking measurements. Apparently, firmware can be updated via Fluke Connect (app for US only I think). Mine was 1.01.00. 378 allows my work flow to be more efficient. The body is solid. Form factor a tad larger than the 376 but feels awesome in the hand. I love the 378. Having my situation awareness widened in the shortest time possible is an amazing experience. If... you are working on high voltages or AC, don't have a clamp meter yet, looking for better workflow, working on compressors or motors a lot, taking quick measurements from phase to phase, and hate to stick probes around, THIS IS EXCELLENT. If you want precision, always looking for the decimal in the reading and working on low voltage stuff, the CLAMP ain't for you. You will need to use the probes with the 378. High accuracy and precise reading isn't what the clamp on 378 was designed for. We need the test probes for that. I also got the Fluke 289 for high accuracy and precision work. This is special because, • Field-sense works well for me. Especially when taking a quick successive approximations of Current and Voltage. IMPORTANT ground/earth this meter properly when using Field-sense. Failure to so will cause Voltage accuracy to go off by huge proportion. New users tend to make this mistake. I use Field-sense to look for Voltage anomaly, not exactly "240.5V" for example, but 238V to 245V are acceptable. • Doing 3-Phase measurements and getting a quick feel of the situation on different circuits in a panel has been a joy. Reading phase rotation is possible only on the Fluke Connect app. US only. • In-rush Current logging is my No. 1 feature when working on motors. Special Feature: Power Quality (PQ) analysis (Current, Voltage and Power Factor) is a useful feature but doesn't have a lot of details like a number. Sensitivity can be adjusted from High, Medium to Low. Not having this feature isn't a deal breaker. When using this meter, my head will either be in... 1. VALIDATION. Quickly clamping around a set of circuits to understand the territory. Usually just to make sure there's nothing weird, Or 2. HUNTING. Troubleshooting a system by hunting down the source of anomaly or failure. Fluke Connect app is useful but not necessary unless you want to stand far away from what you are measuring, logging or updating an earlier firmware. The 378 FC is nice to have but not necessary in majority of cases, especially if you already have the 376. I got the 376 and loving it as well. Got the 378 out of curiosity. Anything that can make my work safer and faster is a money making tool. If you don't do all the above, it's a nice trophy to have. Love yourself. ... show more

Exceptional product. I love the practically bullet-proof case. My only gripe would be the restraint for the meter itself; not very easy to take in and out. A Velcro strap (or two) on an elastic band would move this up in my book. Field sense does not really seem to be super accurate. I opted for this unit instead of the open clampless model, thinking it would be better. It's a ballpark measurement and should not be used as a defacto reading... and yes, I clamped the meter to ground when using field sense and held the wire to the top of the clamps. I didn't even know this specifically would do 3 phase until after I bought it, but quite a nice surprise. I have a 289 for reading voltages, so I am not sure about the lead-reading accuracy of this meter. The fluke connect also seems like an overpriced feature, and sadly will not be buying the subscription as this is my personal meter. ... show more

    • Best daily meter
Best meter for daily use. I can do my rotation test, check outputs on different VFDs, amps, and volts. The only detail is, at the moment, with continuity, it would be nice if the sound could be louder.

    • Junk. Beware.
Absurdly vulnerable for being Fluke's $900 flagship ""industrial"" clamp meter. Simple condensation, due to moving from a cold to hot environment, has killed not one but *two* of these in my attempt to utilize them. For this kind of money there's absolutely no excuse for this lack of performance. Coat the dang board, or something... for crying out loud. Don't buy this pos kids toy disguised as a real tool. 100% I am never buying a Fluke product again. ... show more

    • I have used 2 weeks before writing
I owned last fluke meter for 25 years. It's what the aircondioner supply sold that brand. I accepted their brand but had no idea of quality. I feel it was a solid meter brand making many repairs over 25 years with it. I wish this one did more it seems fluke just can't like some others do more. No temperature and no miliamps for checking things like flame sensor The Bluetooth seems to only work 10 feet. Fieldpiece has temperature, miliamp and easily twice the range which matters to find braker/shuttoff with remote display to phone. I have s22 so maybe iPhone is better. I will say It comes with the heavy test leads making it difficult to find the ends don't when unplugged allow the needle or aligator clamps to be used but test leads has to be changed to allow 20 dollar basic test test set. I don't need fluke 100 dollar test lead kit just to have wire piercing ability. I certainly feel the meter is accurate although other people say otherwise with their meter. Also you can test amps but you want correct true test voltage make sure ground is made and wire being tested is tight against top of jaw ... show more

    • Great upgrade
A great new addition to update my old meter, price is pretty steep but you do get what you pay for in quality and trusting your life with this brand.
