I only accept useful and relevant sponsorsors. I turn down all games, crypto, fashion, makeup, trading, shaving clubs etc etc despite high offers on a weekly basis.
When I was starting out, I was told to check to ensure the clamp meter I was going to buy had both the AC and DC current modes. Glad I did. Had to return the first one as I forgot the advice I was given. The meter I bought more than 12 years ago still serves me very well.
So cool to review clamp-on meters again. My first college co-op job in the late 60’s was to repair these and I learned so much. Back then, nearly all meters were made in USA and analog.
Absolutely correct and detailed video for people who is willing to listen. BUT. For those who just want to know how to stick your probe to something and get it "fixed" "quickly", please CLOSE the video and DO NOT TOUCH ELECTRICITY! Watch the whole video first if you want to "play" with live electricity! You might not only playing with YOUR life, but others as well, if you perform dodgy repairs! Be warned. Thanks for the video!
I know this is an ad, but as an ordinary electrician fluke is all you really see. Even among instrument techs (thet calibrate sensors, sensors which control valves), the 789 is the preferred choice.
I learnt a lot from this - particularly the use of hall effect sensors for DC current sensing!! That's incredibly cool - however, I do have a couple of things to mention: - The directions for current flow used with the clamp-type DC multimeters is called conventional current (TEM obviously know this and the video is correct, but just some added detail). Technically speaking, current flows from negative to positive (electron flow) but that's just confusing and unnecessary for most people - Compounding from the previous point, connecting the neutral/negative first is almost always a good idea, but it won't save you. Car chassis are tied to battery negative, so you should always connect negative first because it can't short against the chassis whereas connecting the positive first means your circuit could short against the chassis. The same idea mostly applies with household circuitry - neutral and ground are tied together, so _theoretically_ you remain in phase with any current if you ground yourself accidentally. However, shorting to literal "ground" (i.e. touching grass) will hurt just as much as putting hot to the same location.
I think you missed something in your point about not always connecting the negative/neutral first. You didn't give an example of when it's appropriate to connect to positive first. You mentioned car batteries, so I think you may have intended to mention that when installing a car battery, you should always attach the positive terminal first (unless you have a weird British car with a positive ground frame). The reason you do this is, once the positive terminal is installed, accidently touching the negative terminal to any metal part of the car (for example, by dropping a wrench in a way that touches the negative terminal and the frame of the car) completes the circuit as normal with all the car's protection circuits in the loop, and 12 volts is so low there is almost no risk of shock if you accidently complete the circuit with your body. If you install the negative terminal first, then if you accidently touch the positive terminal of the battery to any metal part of the car besides the positive cable, you will short the battery, and it will try to dump its full rated current of 600+ amps through what ever you touched it to and the negative cable. Because the frame is ground and directly connected to the negative of the battery, there is no current protection to save you from this mistake. Another example of how this could become dangerous is if, after installing the negative terminal of the battery, you go to install the positive terminal, and while tightening the positive cable, your wrench or tool contacts the frame at the same time, you will short the battery. For the same reasons as above, when removing a car battery, you should always disconnect the negative terminal first, or if you're just disconnecting the battery to do work on the electrical system, the negative terminal is the one you should disconnect.
Of course he did. I found it on my startpage. I sort of live in simbiosis with the algorithm. It shows me videos that really fit in with what I'm interested in at the moment. I rely on it to get new content. By the way! Finally!!! I have been waiting for this video for a long time. It's filling a big gap in my journey of learning to understand what's going on in electronics land. I started my journey in electronics land on this channel. 👍🏻👍🏻👍🏻 🙏🏼🙏🏼🙏🏼 Just yesterday it happens to be that I realised, that I feel comfortable now; being able to follow what is shown in all these videos. Finally. By today I declare myself a well enough educated citizen of electronics land. Following the paths ahead of me. With a much better insight and a relaxed mind. It feels like it took me three years. I'm not sure about that. Will look that up some time. So thank you for being part of it and giving me the opportunity to make my first steps. You guys are really good educaters and the channel also evolved really good. Thank you for being there. Kurt
I enjoy this channel, really need refreshers, and more learning and these videos really do help with expanding my knowledge, some things I get lost at, like with 3 phase power, but at least I can go back and watch it again. Thank you
When I was in college back in 99, the Fluke rep came to visit us. A few of my classmates bought a meter (model 88? 98?) but I couldn't afford their outrageously priced stuff. I think our instructor even told us to think really hard before buying one 😜I got out of that industry not long after anyway.
My fluke is my companion, savior, and a money maker. Its accurate, safe, reliable... And most importantly protects me from myself when human errors occur, only to blame on none other than myself. 😅
that depends on the thermocouple ig? His looks like it has the wires exposed, which would corrode (galvanic corrosion), especially over time But they usually have some cap afaik, either some glass, metal or plastic, which can make them safe to dip (it should say that somewhere on the packaging)
You definitely can. I use my DMM (MTP make), when working on fire alarm systems and would use the clamp for the DC currents that are in the system. Just make sure your meter is set to the proper mode.
my favourite meter is an ancient Fluke10. a bit low on features by modern standards, but it just works and it's yearly calibration never results in any adjustment
very good information, im learning and want to be more electricity smart, no electrician schooling and My understanding has grown no expert but definintly learned something
I still have mine and will use them periodically. I find my digital meter (with the clamp), makes it much easier when measuring current as I don't have to disconnect any wires for this. Yup, I confess I'm a tad lazy.😏
I use Klein and fluke meters. However, when I had to troubleshoot a non-working air conditioning compressor, I used a Klein CL800 (I rotate meters yearly for calibration purposes only). I could not find why the compressor was not working, but the fuses were popping. Another guy comes in with his fluke, sets it to continuity (same as me), and saw that the compressor was grounded. The Klein could not find it. My diagnosis was incorrect, and kept the unit down an extra month because we had to replace both compressors, not just the one. In short, buy fluke. If it’s just a hobby, buy a cheaper fluke. I’m currently in the process of replacing my Klein meters, and will pass them down to my son when he starts learning about the trades.
@@modorangeorge4991Yep, sponsored marketing taken a little too seriously when someone really believes you need a certain brand to find a ground continuity 😂
It's strange hearing a British guy call live 'hot' and demonstrate on an american outlet but im guessing its what Fluke wanted. That Fluke meter is really smart but for £600 I don't think I could convice my boss to get me one.
I remember trying to measure dc current in an appliance wire using a clamp meter clamped over both of the conductors. It was my first time using it despite seeing it in action many times, so it took me some time to figure out why it didn't work...
Dammit HellokittyFanM...if you don;t like the video and information provided, start your own channel and make your own videos? Thanks again The Engineering Mindset!
Very good video that covers the basics. Very annoying to me that some selector dials don't have a white or black dot indicating pointer position. Easy to have the wrong function selected by accident, such as on Ohms when measuring voltage. I end up marking the selector arrow with paint, white out, or marker pen.
You could also connect clamp meters in series with other clamp meters or multimeters just like how you would connect batteries in series to combine their voltages. This combines the voltages of the diode test functions so that you could test LEDs that you otherwise wouldn't be able to test with a single clamp meter or multimeter. Or you could connect a multimeter or a clamp meter in series with any battery to achieve the same results. If the battery's voltage exceeds the LED's required voltage, it will not fry the LED if it (the battery) is connected in series with a clamp or multimeter.
In the ad about fluke you said a calmp meter can measure voltage through the clamp. Between which two points does it measure the voltage? I don't get this.
Yes a DMM energies the circuit for continuity and resistance checks, but only the voltage of the onboard battery so it's only a few volts (3v to 9v depending on batteries used) and wouldn't damage components.
Great video but 2 quick questions: 1) If a Meter has a Min/Max function, is a different option still needed to measure InRush current? 2) If an Amp / Current function is selectable on a Clamp meter does that means readings could be captured via Clamps OR Probes? In other words, if a Clamp meter has a selection for AC Current and Voltage and a different selection for DC Current and Voltage, then it automatic that the Clamp can perform all 4 functions?
Thank you, glad you enjoyed. The min/max will not capture the inrush, it will capture some of it but it won't be the full wave. The probes shouldn't be used and should be disconnected for current readings. I haven't seen one that can do both, they might exist, probably it needs a separate function to work.
me, working with low current sub 30V, ah yes "do not try to repair it" do you mean shove a magnet wire in there? (damaged but working devices are fine to repair as long as you're not working with voltages over 30V, though even 80V dc will be relatively safe, but you still need to be careful if your device is damaged. basically, don't but if you know what you are doing you can, repairing will probably make your voltage rating lower, so a 600V rated cable with tape on it might only protect for 200V or so.) though yeah if you have the money to buy a new one repurpose the old cable/multimeter to a project where it's safe to do so.
Your link says 738 FC instead of 378 FC FYI - The link didn't work the first time I tried it, then the second time it shows it but says it is "Currently Unavailable"
I’d like to ask everyone’s opinion on what OL means on these meters. My research has shown it to indicate Over Load or Over limit. I’ve had this debate with other electronics techs. Most seem to agree with it meaning Open Loop. I respectfully disagree. I have a Fluke 117 and it can measure up to 60 Mohms, if I were to test a higher value resistance would I see OL? Clearly that would not be an open loop. I haven’t tested out my theory. What are your thoughts?
One article on the Fluke website states "If the measurement is higher than the set range, the multimeter will display OL (overload). The most accurate measurement is obtained at the lowest possible range setting without overloading the multimeter." I tend to use, and probably did in this video, OL to mean open loop for continuity and Outside limits for resistance. It's not official terminology (according to their article) but I find it easier to visualise. www.fluke.com/en-gb/learn/blog/digital-multimeters/accuracy-precision
Yes, they sure do, I've covered the subject a few times, but in many of my illustrations, I use conventional current as it's the standard. Also, each time I use electron flow I get a tidal wave of dislikes, negative and abusive comments from people who were never taught electron flow v conventional current.
@@EngineeringMindset I understand your reasoning, and it makes sense from a content creator's point of view. I think the reason that it bugs me is that I grew up in the 70's and even though solid state electronics was present and taking over tubes, I learned vacuum tube theory before transistors because I was introduced to a book (when I was 9 years old) called "Elements Of Radio." It was an old early version prior to the invention of the transistor. It would be interesting to see someone do a video on vacuum tube technology and which way they would go with conventional current vs reality. Thanks for your reply.

Wow you really blew my mind by showing me a DC current and then explaining why the AC-only meter was not measuring any current.

Can you please make a video on “Whats is Impedance,Resistance and Reactance” and whats the difference between them it will help me alot
In essence, resistance and reactance are specific types of opposition to current, while impedance is the overall opposition combining both.
