@jdecouverte2752 hello, merci pour ton commentaire, je te souhaite une bonne et heureuse année 2025 à toi et a ta famille également :) A bientôt

Hello MrDubje. Glad to see you here. Wish you a good new year 2025. In term of reparation, thoses capacitors are sometimes used for many voltage supply in the same time. So if a rail failed, you have a defect product. Do you repair some devices for your own or did your enterprise allows you the time to make it ? Thanks :)

Hello, thank you, wish you a good year to you and your family, greetings from France.

oui des fois ça fait du bien de se laisser aller :)

happy new year man.

Hello Dareen hope you're well. Glad to see you here, congratulations for all your new subscribers. Wish you a very good new year.

Thx Alex! Btw, I noticed you don't have the Super Thanks option enabled for your videos.. ? je recommande vivement. 😅👍

@@KeepOnTesting that's ok I did it as well, thanks for advising. I didn't know the purpose of that thing, thanks :)

on jest wspaniały. Ale mam inne mierniki ESR, nie zawsze używam tego. Ale jest idealnie.

soit tu n'as plus de gasoil (faut refaire le plein :) ) soit tu as un levier détaché dans ta jauge qui fluctue en fonction des virages. Je pense qu'il faut démonter ta jauge/pompe d'aspiration et regarder si quelque chose n'est pas défait

@ d’accord je vais regarder ca et je reviens vers toi merci en tous cas 🫡 j’ai quelques secousses en debut de 2 iemes tu penses ca pourrait etre les injecteurs ? Tu gère 👌

@@maiitre_corbeau7921 je suis pas mécanicien mais tes secousses disparaissent-elles à chaud?

I don't understand your request.

Thanks Sabry glad you like it, hope you're well and hope you will have some time to spent for a coffee or something else.

be carrfull. If it has a short circuit, that means it has a damaged coated wire. So maybe you have to locate this damage and repair it, or using a new coated wire. Thanks for commenting.

on peut mieux faire, mais merci.

no, it doesn't.

not only of course. I made this video to attract attention on very bad inexpensive ESR/component tester, witch are not able to provide a decent value of ESR measurement. At the end of the video, I show a very nice inexpensive ESR/component tester, wich every body shoud have in his tool box. Those discrepancy are not only different frequency measurement use, but also the integrated software, badly designed, who works badly and make the device inoperant. Some inexpensive chinese component tester can be very nice (the last exception at the end of the video) and other are just waste of money. So, that's not only a concern of frequency, but the art to interpretate it.

​@AIexanderHartdegen The art of knowing how to read them also matter.. (you showed a wrong reqding on the 2nd tool 😊). anyway thank you for this nice, valuable video. would you share with us some recommendations on what to buy? ❤

@@ivanm.3522 the first and second tools show bad values. If you don't want to spent a lot of money, the "exception" is perfect. The "blue esr meter" and the analog homemade ones are perfect to read capacitors values on pcb (blue is expensive). If you are ok to dismount faulty capacitor to measure it, you can purchase the last one ( "the exception") on Aliexpress. For less twenty box you will have a very nice multitool. This what I use at work :)

c'est un wattmètre qui existe déjà, que j'ai juste réalisé selon plan et j'ai modifié quelques paramètres au niveau de la programation afin de pouvoir l'utiliser dans ce but. Ma contribution y est très faible, juste réalisé, mis en boite pourrie en carton parce que j'avais pas le temps, et reprogrammé quelques trucs dans le programme afin de le monter très haut en puissance. Je crois que sur le blog il y a des infos dessus, sinon le plan existe sur le net, avec le programme téléchargeable dans un usage domestique.

@@AIexanderHartdegen j'ai lu ta page DIY wattmeter with an Arduino mais ça n'a plus rien à voir là il est sacrement amélioré ;^) si tu as un lien ça m'intéresse merci

glad you like it

ça dépend des étains, et ça dépend de ce que tu voudrais souder. Si tu veux souder des LED, il faut baisser la température au maximum, car les LED sont très fragiles et n'aiment pas la haute température. Les LED CMS sont encore plus sensible, et nécessite des températures inférieures à 250°. La température d'un fer à souder est choisie pour ne pas abimer les composants, ou ne pas déterrioer le circuit imprimé. Choisir la température de son fer à souder n'est pas tout a fait une science exacte, mais varie en fonction des précautions que vous voulez prendre. Si vous voulez dessouder une résistance sur un circuit imprimé destiné à la casse, la température du fer importe peu, pourvu que la soudure puisse fondre. En revanche, souder pour réparer nécessite beaucoup de précaution. La température idéale pour un usage classique répété sur un fer à souder thermorégulé est entre 330 et 350°. Lor de soudage de composants fragiles, comme par exemple un circuit intégré, il faudra utiliser une température assez basse, avec de l'étain au plomb si possible. L'étain peut fondre à 180°, selon le type d'alliage, sa finesse, et l'inertie thermique de la panne à souder. Ce qui allerte sur une trop haute température d'un fer à souder, est la collophane incorporée au fil d'étain qui s'évapore instantanément, le décollement des pastiques, et hélas la destruction des composants. LED, transistors, Circuits intégrés, peuvent être détruits par un fer à souder trop puissant, et a cause d'un prolongement excessif de la panne sur les pattes du composant.

I think you know this model better than me. Of course, purpose of video was to get a response I was asked to people who's wondered the same, about Vega devices. I didn't even know there was a new model as you mentionned. It's amazing device, fiting the pocket and helping a lot. This one is not mine, but to my company, trying it according my advice, to make equipments more accessible. Thanks for commenting.

Hello fixtronic, thanks for your comment, see you soon.

Hello Sabry glad to see you here. Hope you're well and.. Hope to see you soon. Kiss from Istres.

@AIexanderHartdegen I hope too thank you brother good luck in sha Allah

hello, glad you like it.

this device is made especially to test chimical capacitor. This is a capacitor tester, not a reader. So, pF are to low for this device. If you can read such values, you need an LCR meter.

Proskit mt5110 puede medir bajos valores desde 1P hasta 20k uf

@@guateque1718 the device on the video is a chimical capacitor tester, not a capacimeter tester. A real capacitance meter can read until the PF capacitance, like Proskit. But LCR can make both.

thanks.

a simple diode can save you day. Thanks for commenting.

not China, scammers.

Auto mode is nice for electrician, not electronician. This mode can present some different input impdance and it can produce some erratic result, even destruction of your on supply device.

glad you like it.

oui. Personne n'est parfait... Et encore moins moi.

price of the multimeter is 140 dollars.

@KeepOnTesting hello Darren hope you're well. Thanks for commenting and congratulations for your nice channel, thanks and see you soon.

ok

YES.

yes you're right. I just wanted to avoid some bad manipulation and damage the scope. In fact this way was the safest and easy way to reach it without damage. Thanks for informations, and thanks for commenting.

hello sir, the part you're meaning is on a special video called " spodwelder schematic", on my channel kzbin.info/www/bejne/g4aslWdrnrqlhZo . Time is adjusted manually with hand when pressing electrodes. Thanks for your comment.

ce n'est hélas pas dans mon domaine de compétence, même si j'y travaille. Je vous conseille la chaine " Occazout" qui ont un service clientele très honnête et fiable. Dsl

hi it's powered by a real linear heavy (but tiny) classical transformer, copper and steel.

@@AIexanderHartdegen Hi, thanks for the confirmation, should the two new soldering stations: I-CON PICO MK2 and I-CON NANO MK2 also be powered by a linear transformer ?

I agree. This is a varistor. It has done it's job a a bodyguard for the yellow X capacitor and all the electronics. You need to replace the varistor because without it, the whole device will have a short life. I don't think the colour has a big importance. By the way, Y capacitors are actually guaranteed to never cause a short circuit. X capacitors are self healing, but they will lose some of their capacity each time the hesl. I have recently replaced an X capacitor that had lost 80% of its capacity.

Yes you're right of course. But I said it at 13:49. The doubt was erased when seeing the symbol of it on the pcb. Thanks for commenting

@@Oldclunker-ge5zp thanks for your information. I admit that blue color is (I thought) for XY capacitors. But I voluntary make this mistake for discovering the schematic on the pcb. That was the spot. Thanks for commenting.

Sorry if I missed something you said. Normally, a varistor should survive a reasonable amount of overvoltage surge energy without permanent damage. There are different technologies for varistors, there are also unipolar transient suppressor diodes. All of them are expected to cause a short in the worst case. In your case, either the surge was enormous or the varistor was a just too small for its job. I have recently seen one, burst and cracked open, in a 100V mains device where 230V were accidentally applied. It is still shorted and blew the 3 Amp fuse. Job done heroically. I will Just replace the blown parts for 1€ cost. It's a bit sad though that nowadays so many components have become short-lived consumable items. X capacitors have always been notorious for causing trouble, ever since they changed from the huge but virtually indestructible metal/paper aka MP capacitors to the smaller and cheaper plastic film capacitors like MKP MKT. A varistor is much more necessary for protection of MK* capacitors than for the classic MP.

@@Oldclunker-ge5zp Thanks for all informations. I ask the owner of those plugs and he told me than lightning has stroke his line and killed almost all devices, including solar inverter, 20 plugs, pumps, and charger. So as you said, those components made their job but was like a little bit injuried. Thanks for sharing informations and knowledge.

I have a few of them, testing with multiple device when I am not sure. The first you seen is a component tester, it's nice to check some various components and a nice ESR. Other cheap tester are not so good. The second you have seen is an LCR meter, delivered as a kit. It's more versatile, good precision, and give an absolute reading of ESR values. If you have any others questions don't hesitate. Thanks for commenting.

You should check some contact in it. did it happen after a drop ? be carreful, some contact of the glass screen can be broken. look at this kzbin.infoVpfVDxcq4WI

not temperature, but vibration, choc or other twisting effect. Potentiometer are very sensitive to vibration. According the milliohm range variation of the main shunt resistor (wish is a resistor, not a special shunt), it's stay stable, except of flexion or vibration.

@@AIexanderHartdegen more expensive one?

I made the video to help people with this problem to solve it. Glad you like it.

when I found a old one, I will test it like that.

no it use coated wire. When soldering it, it loss his coat and the other part of it is still insulated.

@@AIexanderHartdegen Oh cool. Thanks for sharing! I'll definitely try this out.

Hello NikolaPasulj ce genre d'alimentation coûte entre 100 et 200 euros suivant le fournisseur. Le prix classique est de 150 euros TTC environ. L'alimentation est très bien construite mais les condensateurs ne semblent pas être les meilleurs. Merci pour ton commentaire :)

@@AIexanderHartdegen une belle somme d’économiser !!!

are you looking for batteries?

You're right. You can notice however the last component tester, wich is the only one who can really give a nice value of capacitor. Of course, nothing is better than a dedicated ESR meter, thanks for commenting.

@@AIexanderHartdegen which component tester is the last one that gave a plausible esr reading?

@@guateque1718 sorry YT didn't notice me about a message. Just go on Aliexpress and look for the same style ( style are recognizible by the type of connector). Those tester have the same name. But those one are good, not the others.
