@jstro-hobbytech6 ай бұрын
I made the mistake of buying an expensive scope before I knew how to use it and ended up donating a hantek, tektronix and siglent before I settled on a rigol mso5354. The rigol 1050z is the best bang for buck. It's 400 and all any hobbyist will need unless they got into ham radio or audio and need a spectrum analyzer. They cost a fortune, I can't pull the plug on 2600 for a cheap one.... Most scopes can be hacked too with firmware mods because the companies hide features behind expensive software keys. It's super easy to mod them if you check eevblog. The guys on there are geniuses. I won't even comment and pretty well read and educated for software engineering. Electronic engineering is a hobby, I'm 45 and retired though so I might get an ee degree because my other degree has 3 terms of courses that carry over. Bucket list thing. I read textbooks now as youtube has petered out for me haha. Bored and retired. You're smart for starting with a lower cost one. The picoscope is an awesome usb scope. My buddy works for nasa and he loves his cheap one. If you guys need any free components or anything just email me. I have too much stuff and enjoy sharing. Postage on me.

Something I don't think was mentioned was that there can be differences in the probes (& their wires) themselves. I recently purchased a new multimeter, & decided to get a pair of Probe Master probes for the new meter, and I LOVE them + recommend them to anyone. Aside from the probes, GREAT VIDEO 👍👍👌 Very informational - thanks!!
@markday31456 ай бұрын
I'll second the recommendation for Probe Master test leads. Where I really noticed the difference was in continuity mode on an old and cheap meter; with the Probe Master leads, it became quite a bit more responsive. Coupled with a newer (but still inexpensive) meter, they are amazing. You can also notice the difference when doing measurements of very small resistances, where the leads themselves can introduce some error.

Great explanation on the basic functions of multi meter. Some thing to consider 26:11 in a non faulted AC circuit you should read 0v as shown. But in a ground fault situation you will get leakage current reading on the ground wire. When you do see current reading on the ground wire, the (ground current + neutral current = hot wire current). So in other words if you clamp around the neutral inground at the same time. You get a reading equal to the hotwire . But to reading leakage current in most situations requires a dedicated leakage current meter to read. I know this is a little advanced but ground faults can occur easily without knowing its occurring. But a UNI-T UT210E is a great alternative to a dedicated leakage current meter. I highly recommend anyone looking for an AC/DC clamp meter for measuring (2amps or less) low current applications check the UT-210E (Make sure its “E” model ) out. You can find them in the sub $50 range. I’ve been carrying this meter daily for about 4 or 5 years now for current measurement. Its not my main multimeter. But I use it in industrial environment and never had any issues with it.

Again, I couldn't toss it out. LOL About 3 years ago or so, for fun, I did a maintenance on it and a fresh calibration. The dang thing is sill accurate! Then came those new fancy digital meters! WOO HOOO! LOL My 1st one was a fancy, Radio Shack Micronta 22-195 multimeter. Yup, I still have that too. And it's OLD! Yet, the danged thing still works and shockingly is accurate.

One thing to be aware of is that accuracy will depend on the battery level of some multimeters. In fact counterintuitively, your voltage readings will be too high if the battery on your multimeter is low. This tripped me up for a while when I was trying to measure the voltage of a battery for an IoT device and couldn't figure out why it wasn't working.

One little point that may help people. If you do blow the current range fuse, you can not fit any old fuse of the same current rating. You need a specific high rupture capacity (HRC) fuse.

Love your vids and other arduino related vid. But I have a question, I am a begginer student in electronic engineering (first year, second semester). Currently, I am using an analog multimeter I bought at DIY store (lol). So, now I am in the market for a new DMM. After watching this video, I really like the FNIRSI 3-in-1 Multimeter,Osciloscope and signal generator because it is like the whole lab in a single pocket size device. As a student, this will be very useful to bring anywhere, ie: I can bring it back home, my faculty and even fit my small dorm room. At the same time I dont have to buy other device like osciloscope and wave generator. I would probably used this to learn some basic component like opamp or transistor, with the built in wave generator, this would be very useful. Other than that, I would also use this for arduino project. My question is, it is appropriate for me to buy this? I don't mind investing a lot in my interest as long as It can accelerate my learning. Or there is th other better or even cheaper alternative I can buy? Thank for answering my question.

For a home electronics lab, sure, many multimters will do. For higher energy circuits, I'd suggest getting something that has proper input protection and fuses. There are other professions where multimeters need to be calibrated at intervals. Or procedures are written using a specific meter, and those manuals need to be valid for as long as possible. This is where expensive Fluke meters come in.

15:40 you should keep in mind that when testing for continuity, you are injecting a (low) voltage into the circuit you are probing. If there are delicate components, like precicion analog sensors, you could damage them when simply poking around. at least you should try to keep an eye on the polarity. It won't be critical for hobby electronics, though.

Now this being said, to assess a 0.1% accuracy measurement tool you would need a reference with 0.01 % accuracy.. the Adafruit circuit lacks this accuracy..

@@algre977 The fwd voltage being the same is pure coincidence. The same would have occurred with any other diode or a couple of them in series. The load is only dictated by the constant current circuitry (the resistance+potentiometer). By removing the led, components in series are in an open circuit and the tiny remaining load is just due to the high impedance of the voltmeter. For a usual 10Mohm device with a 10V source (a bit overestimated to simplify the calculation) the charge is only 1nA. On the other end, 20mA is not a lot but it's enough for the small transformer to not be able to rely only on em and capacitive noises leaking to the secondary.

Fluke is “expensive” because government test procedures are wrote based on the use of specific models/ features of fluke and Tektronix test equipment. It would take decades to rewrite the documents. So the government pays a premium for fluke to continue manufacturing out dated meters. Fluke does make rugged test equipment and I own lots of fluke multi meters. But they are now only pulled out for sanity checks. Because most other brands have better feature sets and less expensive than fluke at this day and time. When measuring voltages over 600V I do prefer fluke because I feel they do have a slightly safer front end.
