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 ?
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 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, 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.
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.
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.

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.
The only security is the inscription: BEFORE MEASURING, UNPLUG THE CONDENSER !!! And from the company practice, there will always be someone who will connect a charged capacitor, damaging the meter.
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.
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
I think T4 version. The Gold tile and on it is written that I have HW-308 whatever it means. I downloaded the firmware from https://www.elektroda.pl/rtvforum/viewtopic.php?p=16666668#16666668 and unfortunately the display shines. shows some passing characters instead of logos and Polish characters. I compared the tile with the one from the author's photo of the above-mentioned topic and it is identical! I suspect that the Chinese used a cheaper display and this is the problem. Does anyone know anything about the subject? Maybe someone has improved firmware?
Gentlemen, I bought this tester (without a housing) and found that for greater safety in use and easier movement it is better to put the battery with the tester in one housing. At the first measurements, I dug out a box with old elements and, by the way, found a power supply that once fed my mother's calculator in deep PRL. I thought that since I want to put the tester in the housing, it can use this power supply?
UNITRA ZATRA power supply model ZS 0.15 / 9/3 220 V; 50 Hz; 5.5 VA 9 V; 150 mA
My question, could I use this power supply to power this tester ??? Possibly, what changes I would have to make. As you probably figured out, I'm just starting to play with electronics. I will be grateful for your help.
