with some leads you could id board components

From the documentation 1.12k self test calibration requires capacitor between 100nF and 20mF (even though tool only says > 100nF). Using 100mf does not complete the calibration as on completion it displays the calculated calibration values. I was constantly being told it was not calibrated. It was only after reading the manual on the link mentioned by the tool that I used a 10mF capacitor and the final phase completed with an extra page of info. No more nagging about calibration. Hope this helps someone looking for additional info. Great video!

I just bought this thanks that calibration makes sense now

Life saver of a video. Well done mate. Bought this device in kit form from Amazon and it came with absolutely sweet FA documentation! 👍

Thank You , you saved me a lot of time today. I spent one hour playing with it, figured out some of the function procedures then decided to search YT and .....VOILA! 12 minutes later, I'm all set

great video, I just bought one, put it together, haven't tested it yet, can't find a nine volt battery in my house or shop!! Thanks for showing all the details of testing, and the functions, I got a lot more than I thought.

Nice review! _And the bonus clip is like a cherry on top._

Just got mine in the mail and excited to test it!

I should get one. I have drawers full of small components from breadboard projects I was too lazy to put back in the right place. Especially 1/4 watt resistors, zener, and switching diodes. Fun video!

Excellent video, thanks for sharing!

Ordering today. thank you for the detailed video.

Not too fond of the start of the video, but, the content after that was really informative. I got one of these yesterday for free! I used to have a Radio Shack transistor checker but who knows where it is now. I didn't know what this was when a friend gave me one until I got home and really looked at it. Your video helped me get it calibrated and show me how to use it. Thanks! Thanks also for the link to the manual.

That little handler scope meter is nice

Thanks for the video! I just got one of these but had trouble finding any instructions Got both the manual and a run through of operation 👍 Plan to use 2x small mobile phone batts (~7.4v) for power which will fit in the case

Like. watched for the second time. I have the simple version but spilled coffee on it, so today I have the GM328A and printed the manual. Thanks for that. After killing the first one it felt like loosing my phone, I became dependant on the gadget. New gear! $16 w/case, I'm excited.

Great video as ever and a great piece of kit at the price!

Thanks for the video, very handy, I just bought one, cheers

easily one of the best channels on youtube, please keep it up :)

Didn't even know these existed in such an inexpensive form, thanks!

As far as I am concerned the only helpful part was the last quarter of the video. I stopped the video and use the advancement bar on the bottom to move forward to get still pictures of the finished product, which that helped out greatly. To start a couple of the pieces were thicker and I had to file down the tangs to get them to just fit. Now except for the very top I put the bottom and the sides together first " I didn't but rubber bands probably would have helped to keep things together as you advanced". Next I removed the screws and "long nuts" from the GM328 unit, you will not need them. Next the 4 shorter "long nuts" go on top of GM328 which screw under GM328 into the shorter 2 "long nuts up in front of GM328 and repeat with the longer "long nuts" in the rear. Now drop everything except the acrylics pieces inside of bottom half and use the nuts to attach. Now all that's left is the top 3 acrylic pieces. in order, start with the large piece on the bottom, next the piece that has the cut out for screen and the last whole piece on top. Set it on top of bottom half. I had to squeeze at tang attach area's to make sure they were firmly attached. YOUR DONE. Except you need to make an extension arm for the lever with a tube or something. Sorry I'm still working on it. And Yeah, Patience is the name of the game. Have fun and good luck! I spent about a little over 3 hours, Argh! Lol

Excellent video. Many thanks.👍🇬🇧😷

Thank you, great video.

Cool video, thanks Schematix! I have 3 of these now that all look different but i know they all use the same M328 chip. I cant help buying them....bit like buying multimeters! Just gotta try the next one too...lol! Thanks for showing!

Useful video. Thank you.

very good testing .

Great video

The moment you started wrapping the 9V was the moment I subscribed. :-D

Great review dude... 10/10

Very good.

Your "cool bro" should be featured more often. Reverse polarity must be his speciality 😂😂

Useful item

I wish I could have a better understanding of electronic components more than the small amount that I do. I want to learn to know what they are and how to use and diagnosis them so I can know if they are good or bad. I would also love to make things as well but my primary desire is to diagnose failures.

belle vidéo merci

I wish I had one of this device too.

tanks bro👏

I bought one of these but upon assembly it didn't work and the screen was damaged. Never got it to work, but at least I got some soldering practice. Might buy another one tho, I heard these are the better ones.

otima aula parabéns abraço.

One small thing i found with these testers... they can-t identify zener diodes properly. They detect the forward voltage, but not the zener/reverse voltage. However, you can sometimes trick em by putting a small signal diode in reverse-series with them, and then subtract that diode's forward voltage.

Handtech scopes are pretty cheap on ebay, round $300 for a 100mh model, and that can be upgraded to 200mh with a firmware update. its what i use in my lab and it serves me well. i also have a crt scope that i picked up for $20 at the local recycling center. i have also recently found an awesome tech recycling company here in chch so if there is anything your looking for let me know. got a huge pile of stuff there last week, including huge IGBTs and a 5mw laser!

Good tester have a few of them

I like mine not just for identifying components but testing them, especially transistors, it will tell you if they are good or not. its also in colour. It also came with leads for on board testing and some other bits and pieces and a usb conection for power or charging. I paid €13 ($21 au) including postage

What is on the market today that matches the functions of this device? Are they all a lot more expensive? Have our options improved in the 3 years since you made this video? Thanks for what you do

I have a $5 monochrome single-button one. It's fairly exact and doesn't go through batteries. This should be a bit more powerful due to rotary click encoder but for most things, i really don't care.

Is this still the best cheapo function tester? It seems to give a tad more information than the 5USD ones with just a testbutton, and that click-turnknob does seem to be handy. Thx for the vid.

If you are going to test capacitors, make sure they have been discharged. These component testers will quit working if hit with a charged capacitor. You end up with a spare display and a zif socket.

Could you please do a video using this for measuring lithium battery esr

I'm curious as whether one can test Jfet transistors on this device.

2:30 what is the polarity of power adapter(center positive or center negative) I should use and what voltage/current ?

Regarding the f-Generator from min.10 .I bought one and it doesn't have the default frequencies for me as in the presented clip. It appears written on three columns -f-Generator., 1Hz and f-00Hz. I don't know what the cause is. from software?

Is a pendalum clock going in the behind?

hi do you think I can use it for the motherboard testing in microsoldering ?

This dude sounds like a group on the same block as Jim Browning

Could you tell me what is the difference between the GM328 and GM328A versions?

How can I restore the backcolor? accidentally set the backcolor green and this is confused with the green fonts of the frontcolor, so the screen is all green

I don't know if you put the box together in wrong way or your missing something or they send you the wrong box . But I have the same one that you have exactly and iam sure that not the way to put the box together because you're LCD is not covered under it and your battery not supposed to be moving around like that

Your next video should be which of the dozens of those small cheap component testers on eBay are the most accurate, latest firmware etc.

Will this check esr of capacitor in circuit?

Mine just displaying Vext=0mV what might be a problem with this...

Great review - could you please tell me who you purchased your tester from? There are quite a number of very similar lookalikes on eBay and virtually all that I looked at did not come with the user manual. Cheers

It says for the calibration to use a capacitor between 100nF and 20 microF, did u use a 100 microF and is it ok?

how do you test SM parts?

Mine doesn't work, where can I get the code for the atm3l chip? I want to put. It in an arduino and rewrite the code

Frequency counter test?

Can you tell me what you get when you go to MENU and CLICK on Show Data? What version is at the top? Mine, 2017: 1.12k and my 2018 1.13k Is your version 2019? Does anyone have 2019 version of this GM378 tester? Thank you.

Boa noite meu amigo como monto essa caixinha

Anyone know how this cyan contact press part is called, please? Edit: TFXTDOL, found it.

You know, I didn't watch the video to understand how the transistor tester worked, but to understand how i assembled that bloody acrylic case that came with the tester.

so it gives pin out etc, but does it tell you if component is good or not?

This won't test for a bad transistor?

Mine came without a knob knob. Need to buy one.. first see how to measure the size.

'Amazing how those little computers can identify stuff. I have one of the simpler models without the PWM or voltage meter. Do you know what chip yours uses?

cannot test the zener diode

I ordered one of these from Aliexpress and it looks identical to that one except the menu is in Russian and illegible tp me.

That's just great, somehow on ended up on this video wasting my time typing on how to put together Acrylic case shell together. Argh!

So the esr test on this is poor?

You may want to look at the original open Source Design of these Testers at www.mikrocontroller.net/articles/AVR_Transistortester#Introduction_.28English.29 ( English version , other language Versions also available).

HAY, THANK YOU! i almost bought this junk! for $17 their are better testers out their and you should consider reviewing them. if your going to do this you will need to spend the money. an attitude like yours at 915 8.84H is not acceptable! their is a "DANIU™ LCR-TC1" which is different and i dont think its a signal noise genererater but for identifying parts at $17 the same price perhaps its a consideration.

Pun 1... Pun 2.... Pun 3....

that same 9v energier battery leaked and destroyed my device
