    I coped with the display - I scraped the groove in the housing for protruding glass and ribbon. The possible advantage of this sculpture is that the display may not fall out, aesthetics .... well, the mill did not do it but I think that some veneer will be either painting because I do not like transparent covers. Added after 4 [hours] 53 [minutes]: The tester has one more hidden function - CIK-CIK ? LCR-T4 electronics components tester ATMega328 - Test and Review

    Unfortunately, in the current batch of testers the display on the side of the tape (connection) is wider, which causes the display glass to protrude beyond the plate.
    And I remember when they blurted me out when I asked for the instruction to fold, because I did not fit the elements :D I managed it this way. It was necessary to detach the display in order to cut off a piece of pcb and additional milling of mounting holes because the button is also slightly moved.

    Hello, do these testers see the IGBT transistors? Somewhere I saw a photo of someone IGBT was measuring ... or it seemed to me ...

    Only after changing the software. There was something about it in this thread.

    Is it possible to buy a ready device somewhere? i.e. with the changed soft as in the above link.

    Hello, I have a similar miracle Portable HW-308 ESR Meter Transistor Tester Digital 12864 LCD Screen Tester and a problem of this type that does not detect coils ie inductance but only winding resistances. What could be the reason.

    No coils or only those with a relatively high resistance of windings? Mine is like that :cry:

    Mine can measure the capacity of the test leads, these are around 20 Piko.

    Different testers, but the measured elements also differ. Thus, it is not known which conclusion to make of it? :cry:

    The fact that they are different is of little importance in this case. It was not about comparing them (accuracy).

    ... refers to the above statements. The point is that two different ones measure what others do not work.

    Hello, I am asking the Society for advice, I am going to buy such a tester on ali, as I am an amateur amateur and I will test rarely and occasionally and I do not intend to improve, reprogram or exchange for a newer model, I want to buy optimally. Unfortunately, so many versions with different software have already come out that I find it difficult to catch up, in effect I chose the following models: LCR-T7 - supposedly with detection of D. Zenner and IGBT https://tiny.pl/tt9tp " target="_blank" rel="nofollow ugc" class="postlink "> https://tiny.pl/tt9tp and for self-assembly (what I'm afraid of), but with the generator and as I see some other functions, 2018 DIY kits ATMEAG328 M328 https://tiny.pl/tt9t2 " target="_blank" rel="nofollow ugc" class="postlink "> https://tiny.pl/tt9t2 rather, I am leaning towards the other, unfortunately I did not have any in my hands and I do not know what to expect, and do they fundamentally differ in something other than soft and few exits? Greetings.

    On YT you have several tests of such testers even for self-assembly. I bought mine after seeing but unfortunately as I wrote it is not quite ok with it but the zener diode detects those with lower voltage. I have not tried IGBT because I do not currently have one.

    Hello, and it has happened, I connected to the LCR-T4 tester, as it turned out not fully discharged electrolyte. The tester died. Is there a chance to revive him or just exchange? Pozdr. K

    Most likely, the cpu ports were damaged, after replacing the cpu and programming it should live. Check the accompanying elements of the cpu. Well, unless it so flashed that there is nothing to collect ;-)

    In other words - replacing the tester .... It is a pity that there is no security there.

    I have not seen capacitors of this type in capacitor meters. The only security is the inscription: BEFORE MEASURING, UNLOAD THE CONDENSER! And from the company practice, there will always be someone who will connect a charged capacitor, damaging the meter.

    There is still an option that someone in your area will program the processor you have purchased. Probably also in another place will be a helpful person.

    A colleague did not meet much ;-) In my tester Fri T7, which perfectly matches the TC1 tester diagram, which in turn can be viewed in this topic: https://www.elektroda.pl/rtvforum/topic3402823.html there is a security element titled. SRV05-4 (there are application notes on the net). I was saved by a processor in one of these testers, although it was "short-circuited" by myself. But after removing the element, the meter came to life, However, in another copy of the tester, unfortunately, the item failed and ended in processor damage. I would like to add as a curiosity that this first tester was damaged by ... the same tester. Namely, the T7 tester (also TC1) enables measurement of Zener diodes. On the terminals K and A (in the above-mentioned thread are pictures), a voltage of approx. 40V appears. I accidentally put a capacitor in it, and when I realized it, I translated it into the right terminals without thinking. Without unloading ... ;-) or rather :-( That is why K and A are currently covered with a piece of adhesive tape, which I remove only during measurements of Zener diodes, which take place quite rarely.

    Of course, I agree with the above. Nevertheless, a colleague who has been damaged by the tester may look at the tape to see if there is a security element in his device, similar to the one I mentioned above. Greetings.

    Unfortunately, there is no SRV5-04 on the board :(

    In that case, he took a slingshot ... The question is whether to play in resuscitation? I took one look at the eyed-eyed ones - Ali's TC1 or T7 testers are now 15-20 $ circa, maybe you can shoot cheaper (less than 2 years ago about 30 $). Maybe it is worth going in this direction? You will have a "ready", i.e. with a ready casing, a rechargeable battery (charging by a standard microUSB), even with the Zener diode measurement up to 30V (you only need to be careful ;-) ). And with some sort of security, but a guarantee that it will always be protected. Well, but always a bigger chance than not at all ;-)

    Then you have to specify what software you want to program and what software version you have.
