@@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.
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 :)
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.
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
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 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 ?
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.
@Adrian202 I tried with 1 and 3 but it only works one way and is unrecognised in the other polarity. Tried multiple capacitors including Panasonics. Same thing. Weird.
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 ,
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 :)
@@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.
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.
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 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 :)
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 )))).

I love it,, Very handy device,, got mine a week ago :)
Looks good, I've just ordered one :)
I still have it :)
Working batteries don't get recognized from this device but a dead one shows up as a diode.
I don't think it is design to test batteries, they design it to test capacitors, but that's not the same
Wish there was a comparison between measured ESR and what's on the datasheet.
Sadly, I'm not that professional :)

Fantastic video .I wantbto know can I test zener diode ? And find rhe voltage of zener diode??
Sadly, I don't have a zener diode to test, so I can't confirm that
Can this device test voltage regulators?
I think it's testing only basic components
@@Adrian202 Thanks.
After 2 years, did this device prove to be reliable? Thinking about buying one.

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

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
It's $2 case, you can cut open a hole and put some plastic battery holder easy.
hi sir how come this tool can find out the component it is measuring, for example resistors and other components?
This tool will recognize element (that support) and in same time show value of that element depending on what is that
@@Adrian202 What does it affect, sir, is it the component of the tool or the program?
Mine wont read capacitors with reverse polarity the positive lead has to go in pin 1 and neg on pin 3.
Polarity should work in both direction, You just need to have one leg in 1 and other in 2 or 3 I think.
@Adrian202 I tried with 1 and 3 but it only works one way and is unrecognised in the other polarity. Tried multiple capacitors including Panasonics. Same thing. Weird.
Can I test components in circuit if I connect leads to it ?
You should not do that, if You have many connected capacitors it will show combined capacity.
Does anyone know at which Frequency is Inductance tested with this unit? thank you so much
Why you stopped making videos?
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 :)
Hi, can it read the capicitance of a Ceramic smd capacitor?
I think yes because it will be similar as electrolytic :)
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 ,
How would it show an open circuit or short circuit on a Capacitor ? tia.
I never wonder that, probably as resistor, interesting question
Can i test smd capacitor or resistor
how do you know which place to insert legs
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 :)
@@Adrian202 thanks
I like this but it cannot read guitar pickup inductance, he sees it like pure resistance.
Sorry but I don't know to much about electronic in guitars :( This tool test most popular components maybe it's out of range ??
@@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.

Czy ten sprzęt się kalibruje?
Podejrzewam, ze cyfrową przez oprogramowanie więc można powiedzieć, ze nie
Just got it but not so clear on what inputs to use to check things.No instructions on that.
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 found that both the top and bottom rows are the same-1231111.

Com esta case, o medidor perdeu a função de testar componentes smd.
Yes, it's not designed for SMD and SMT (Only transistors)
@@Adrian202 Thank you for your comment. 👍🏼
you should pick better sound. maybe narration would be better

Скажите, пожалуйста: "Какую версию лучше брать: на русском языке, или на английском?"
There are two versions ??
@@Adrian202 Да. Есть русская, и есть английская версии.
the rapid motion of assembly is not helpful
