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.

It is a pity that there is no security there.

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. Quote: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.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.

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 carefulUnfortunately, there is no SRV5-04 on the board
). 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
