Baffled by NPN transistor. DMM on diode setting: good. Chinese multitester: good. DMM on Ohms setting: getting readings between Collector and Emitter with probes placed in both directions. with other NPN's: no reading between Collector and Emitter with probes placed in bother directions.

Thank you! A fantastic presentation, short, easy to understand. I'll definitely be following your presentation on my analog oscilloscope

What if it won't show a reading ?

How did you go from 8.3 to 8.6. that through me off

This is very Nice!! Thanks for sharing. I have been an XP 30 player since the mid 2000’s. Very special sounds I must say. It’s worth holding onto IMHO

why have i been so affraid of learning this ?? this video is awesome ! thank you very much for this awesome tutorial now i can finally use my oscilloscope for more than just looking at the waveforms 🤣

hahaha... ambient? this is just lame basic random notes with a new-age-ish vibe

Can you measure human body frequency with this?

Thanks for the video - I tried that on several transistors (mainly 2222As) - some of which were straight out of the box. With the 2000 kOhms setting selected I was still getting an out-of-range both ways and across all and any of my pins. Tried across about a mm of my skin and getting a reading as predicted so I guess the multimeter is OK. Any idea what I might be doing wrong?

I have analog tek. 2225 scope and when i attempt to use ×10 mag. To mesure rise time my scope shows a high amount if horizontal jitter and it results to impossible counting of time devisions Could you gess which components suspect to failure I already replace all electrolythic caps. They hav high esr or leakage but issue not solved

Would love to have everything u need to get into electronics n such. Where to get a cheapsh but good osilasopce?

Very helpful thank you!

Thanks for this great video. Really really appreciate ♥

Would have been nice if you showed how to set the oscilloscope up also :)

Be aware that the leads on an _analog_ multimeter have reverse polarity for such tests. That is, the red lead is negative and the black lead is positive battery. If that 's confusing, simply swap the lead connections on the meter for the purpose of this type of test.

I am looking to find out what determines the strength if a transistor High ohms or low ohms on which pins. thank you. enjoyed you video very clear c];-)

is it possible to measure it from 0 to 100%? or maybe like making a direct porportional calculus?

thanks

Imagine I used a step down transformer and dispalyed the output voltage on my oscilloscope. My measured frequency is 122Hz but am confused since I know the transformer doesnt change the input frequency only amplitudes. My input mains is 50HZ. WHAT JUSTIFIES MY 122HZ GOTTEN AT THE SECONDARY OF THIS TRANSFROMER ? ANSWER NEEDED PLS!

If that is an ac signal how do I measure my frequency?

Thanks for the video!

Does the transistor have to be removed from the circuit board to get an accurate reading

SO EVERY TRANSISTOR I HAVE IS DEFLECTIVE ACCORDING TO THIS..ALL 200 TELL YOU FOR SURE NOT.I HAVE A CEN TECH 95683 DIGITAL CLAMP MM I MUST HAVE IT SET WRONG... NOPE I GOT IT AS LONG AS I SET THE METER AT THE DIODE SETTINGS OF THE OHM AREA..BUT THAT CAN'T BE RIGHT?

Good Stuff, Don't know if it's understood, NPN, The Emitter is Not Pointing, iN. PNP is Emitter Pointing iN. Good you explain to determine which is which, in a bind and no internet, you can compare to known good Transistor. I do a Quick check of Transistors by Testing like 2 Diodes?. Important Stuff

Many thanks, Andrew. I have subscribed. One question though, "what are next weeks lottery numbers?" Once again , thanks. 😷

Would help if he didnt mumble. I got bored way too soon

My oscilloscope is very old and the only knobs it have is V INPUT with selection X1 , X10 ,X100 and the second knob have selection for frequency x1, x10KHZ, 100KHZ there is no knob for time selection in milisecond like yours. How can i measuer 20,75MHz IF frequency for FM tube radio with this piece of shit. My oscilloscop is the LBO-310 model.

Buy a cheap transistor tester!

Thx dude

Very good Sir!!

Hello can I get accurate reading if tested while still solder to the pc board? Thanks.

So what is the period?

Do we use the same test for an IC that has 3 terminals and looks the same as this transistor? And do we have to take the IC from the electric board like we do with capacitors?

But I don't have an oscilloscope. Can we calculate rise time of a frequency from formula?

Cool weird

vocal ffry!

Very helpful. Thanks!

critical information consistently left out. can the component be tested in circuit or not?

Need a amplifier

You have to eat more , your voice so dead

I was relieved to see a cheap Harbor Freight multimeter shown as that's what I have beside my 1990's vintage Sears analog meter. I love your voice. It's is incredibly calming. Most of the day I feel like my brain is on fire but listening to you has me feeling like after I take a Xanax (calm)

went tot the fucking point

Whispering? It's sucks!

if no current flows through base and emitter in an npn transmitter ,does it mean its a bad one?

This is the best video out there about understanding oscilloscopes. Very easy to understand 👌🏼
