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

  • Always Dependable...
I love using the meter working on electrical upgrades on my home. Used it for working on my HVAC units and my main power panel in my garage. Works great! If you do work on electrical systems or on electric motors, this meter does not disappoint. I have used Fluke meters for years in the lab when I was working; they're always dependable. ... show more

  • Versatile
Meter is ideal for single and 3 phase power as well as solar or other DC since it can measure DC amps via the clamp. Fluke connect is a plus for remote monitoring and PM work. Being able to determine phase rotation is a plus for motors. Non contact voltage measurement is a nice feature for identifying cable runs. Big meter but it is the goto meter for everyday use.. ... show more

  • Outstanding
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

  • Fluke clamp meters are overpriced and poor quality.
I have had several fluke clamp meters, but this one is HUGE! It is super long and heavy, it doesn't fit anywhere. The leads have removable probes which is ridiculous, and that makes the probes super long. It's like using pencils attached to the leads. The resistance measuring is crap. I can touch the 2 leads together and they won't even show continuity unless I mash them together hard. I've only used it a few times and I already hate it. The carrying case is massive too, about half the size of a loaf of bread. I bought my 9 yr old son a Kline for less than $100 and it does everything this one does and it's half the size. He wanted to be like me, but I couldn't afford another fluke. He uses the Kline for his electronics half the time and as a hammer the other half. It seems to hold up fine. I had a 336 that lasted a while until it started to eat new batteries overnight. Then I bought a 376 that would turn off every time the jaw opened from new, but eventually the rotary switch broke. So this is my 3rd Fluke clamp meter, and I'm just a farmer. ... show more

My husband uses this meter on the job. He says it saves him so much time and does way more than he thought it could. Great purchase!!
