Geekcreit® LCR-T4 Electronic components tester - MUST HAVE !!

www.banggood.c...
I found on Banggood electronic component tester and because the price is so low I buy it.
There are other versions but I liked one with acrylic case.
Acrylic is not damaged in transport and device work great.
This device allow for easy testing of many popular electronic components like resistors, capacitors, transistors, diodes, inductors and hard to say what more :D
I found only one component that it can test and that is voltage stabilizator :D
If You play with electronic or if You want to start get it !! From now this will be My favorit tool !!

I love it,, Very handy device,, got mine a week ago :)

[@2008Overkill]

Looks good, I've just ordered one :)

[@Adrian202]

I still have it :)

[@joeroganpodfantasy42]

Working batteries don't get recognized from this device but a dead one shows up as a diode.

[@Adrian202]

I don't think it is design to test batteries, they design it to test capacitors, but that's not the same

[@zynix27]

Wish there was a comparison between measured ESR and what's on the datasheet.

[@Adrian202]

Sadly, I'm not that professional :)

[@zynix27]

​@@Adrian202, it really isn't a big deal, even though it perhaps might sound so. The biggest hurdle is to identify the capacitor model and manufacturer. Some capacitors might come with no identifying data, but the higher quality ones usually provide at least the bare minimum to make it out. If identified successfully, looking up the capacitor series datasheet on Google should reveal the ESR value, unless the manufacturer decides not to provide ESR and tan δ values at all or provides for a frequency different from the one at which the tester measures.

[@FrankJCarver]

Can this device test voltage regulators?

[@Adrian202]

I think it's testing only basic components

[@FrankJCarver]

@@Adrian202 Thanks.

[@MrCacciLLo]

Does anyone know at which Frequency is Inductance tested with this unit? thank you so much

[@victorb22622]

Why capacitance give not accurate result

[@Adrian202]

It's not a professional device, so readings can be bit off. Also, capacitors have (I think) 10% accuracy. You can always compare that to multimeter with capacitor function, but We don't know if that one is accurate.

[@moabdulhamid6839]

Hello,thank you for sharing, I bought the t7 but I think it was defective in the knn area so I returned it ,I like the t4 but I think it does not have the case plus I have to change batteries,is it possible to connect a rechargeable lithium battery.

[@Adrian202]

Device use 9v battery, Lithium will have 8.4v so that could be too low, There are 9v Lithium batteries in shape that this one have, but opinions are not the best (when I last check it) You need to check input voltage range but still device don't have low power cut off that mean it will destroy battery by over discharge

[@electronicsideas1361]

Fantastic video .I wantbto know can I test zener diode ? And find rhe voltage of zener diode??

[@Adrian202]

Sadly, I don't have a zener diode to test, so I can't confirm that

[@mahedihassan7611]

Can i test smd capacitor or resistor

[@WilliamVG]

After 2 years, did this device prove to be reliable? Thinking about buying one.

[@Adrian202]

Not many times I use it because I mostly use multimeter. But when I work on soldering practice kits I use it, and it's much faster to identify all resistors :) Still more professional multimeter will be much better and I don't think it will show same values, but this device is more to identify than show precise values :)

[@alianbaba9330]

Why you stopped making videos?

[@Adrian202]

Nice that someone is interested :) Not much going on with RC, I don't have time for it I play games now, I could show that :)

[@kokor7409]

My issue is with the acrylic case's poor design. Main issue is that to change/replace the 9V battery you have to remove the whole top cover. I'm planning on cutting the bottom cover somewhere between the bottom and 1/3rd way up so I just open 2 screws to replace the battery.

[@steveblakeway4632]

Some of the acrylic cases have a part-ready-cut area of the base to accept a battery-holder, such as eBay item number: 293762628414

[@wybuchowyukomendant]

It's $2 case, you can cut open a hole and put some plastic battery holder easy.

[@Alexandre64842]

Com esta case, o medidor perdeu a função de testar componentes smd.

[@Adrian202]

Yes, it's not designed for SMD and SMT (Only transistors)

[@Alexandre64842]

@@Adrian202 Thank you for your comment. 👍🏼

[@jimmclay2353]

Can I test components in circuit if I connect leads to it ?

[@Adrian202]

You should not do that, if You have many connected capacitors it will show combined capacity.

[@user-kw4gc4xq1e]

[@porlockos]

Is that normal that from some time to time especially when turned on witch cap installed it shows ESR = 0 Ohm and test need to be repeated few times before it show ESR readings, or mine is damaged ?

[@Adrian202]

Device could do calibration on start, so turning on with component could change parameters

[@porlockos]

@@Adrian202 it sometimes don't measure ESR even when i turn it off without component. Did you ever experienced that kind of behavior that ESR was 0 and start showing right after some time ?

[@danvelgtr]

How would it show an open circuit or short circuit on a Capacitor ? tia.

[@Adrian202]

I never wonder that, probably as resistor, interesting question

[@RandomFAI]

hi sir how come this tool can find out the component it is measuring, for example resistors and other components?

[@Adrian202]

This tool will recognize element (that support) and in same time show value of that element depending on what is that

[@RandomFAI]

@@Adrian202 What does it affect, sir, is it the component of the tool or the program?

[@theownersafrica8994]

Hi, can it read the capicitance of a Ceramic smd capacitor?

[@Adrian202]

I think yes because it will be similar as electrolytic :)

[@victorb22622]

Yes,but when you measure capacitor ,insure to discharge first.if you measure same capacitor,it will give different result i observed ,it's just because it get charged when you first measure it ,

[@Michael-ew5kj]

how do you know which place to insert legs

[@Adrian202]

There are numbers next to socket. There is 1 2 3 and anything else is 1. You connect to any different numbers like 1 and 2 or 1 and 3 and device will detect what is where conencted :)

[@Michael-ew5kj]

@@Adrian202 thanks

[@absolutely_senna]

I like this but it cannot read guitar pickup inductance, he sees it like pure resistance.

[@Adrian202]

Sorry but I don't know to much about electronic in guitars :( This tool test most popular components maybe it's out of range ??

[@absolutely_senna]

@@Adrian202 No problem is not the range, guitar pickups have inductance about 2 to 7 maximum 8 Henry. Probably this device cannot test inductance guitar pickups because it doesn't have low frequency generator.

[@Adrian202]

@@absolutely_senna that may be good solution :)

[@sfmag1]

Just got it but not so clear on what inputs to use to check things.No instructions on that.

[@Adrian202]

So to assembly just watch My video or pictures of this device :) As for use there are 3 pins and You can see mark over testing port. top row start with pins 1 2 and 3 and all other pins also all pins on bottom row are 1 so depending on what You test You can connect it to any of 1 2 and 3 pin and device will detect what it is. I described this in subtitles, sorry I just don't like to talk on movies :)

[@sfmag1]

I found that both the top and bottom rows are the same-1231111.

[@Adrian202]

@@sfmag1 That may be My bad but I did not test if that is all 1111111 so You may have right but mostly is no mater on what pin You connect unless they are same pins :)

[@Ksawery_Ksawerski]

Czy ten sprzęt się kalibruje?

[@Adrian202]

Podejrzewam, ze cyfrową przez oprogramowanie więc można powiedzieć, ze nie

[@mooredelira]

you should pick better sound. maybe narration would be better

[@Adrian202]

That's an old movie, but now people complain about My English :D

[@mooredelira]

the rapid motion of assembly is not helpful

[@Adrian202]

You know that you can change play speed on KZbin, right ??

Скажите, пожалуйста: "Какую версию лучше брать: на русском языке, или на английском?"

[@Adrian202]

There are two versions ??

Прибор подделка, померяй конденсатор с материнской платы, он у тебя покажет еср 0.00 ома, а должен показать 0.01 ома, и будет показывать 0.00 до 0.07 примерно, до этого значения он не способен видеть сотые ома, при этом конденсаторы в материнской плате при 0.1 ома считаются плохими, а он тебе может показать при 0.1 ома только 0.03 ома )))). Качественный прибор т4 который меряет 0.01 ома имеет голограммы и логотипы на обратной стороне платы и не имеет 2 точки возле кнопки теста, а этот подлелка из некачественных деталей имеющие большую погрешность, по этому он не может точно измерять в сотых потому что сам с чего попало собран, хитрыми китайцами, которые начали собирать эти приборы с плохих запчастей имеющих большое отклонение от номинала схемы
