Trigger level can be adjusted with the up/down buttons, after pressing the "Trig" button in order to enter the trigger menu.

I have a 2D72 and it's a convenient tool but I really don't like the display, it's too small. I opened it and realized that it's a 2.8" mainly due to what seems to me like a bad PCB design with a highly recessed USB-C connector. Still, I was able to design a new front cover and fit a 3.2" display as there is a fully compatible IL9341 one. The original scope is untouched, existing parts are reused with no modification, I'd say the hardest part is to cut the plexiglass cover ;D, all the rest should snap-in just right

FWIW I got an Owon HDS272S.  Night and day better.

I'm returning the Hantek though not yet sure how.

I also got a Fnirsi 1013D tablet DSO,  So far it appears to be a nice solid 30 MHz DSO which simply needs good software.  I bought it in hopes I can find time to make some small contribution to cracking it open.

No one knows how a tablet DSO should work.  The 1013D is a good test bed.

Have Fun!

I've tried the Owon as well - I agree it's better from most point of view and that's also what pushed me to at least change the screen as the HDS272 is 3.5 and that's much more comfortable.

Madri:
Hello, please, I have damaged the 2c42 tester by measuring in alternating voltage when I had it in ohms. I have changed the resistors R14 and R15 that were burned but it remains the same. I have measured voltages in the area that I indicate in the photo and where there should be 5 volts there are 4.94 volts which seems to be fine but where there is -5 volts I have measured -3.4 volts. And the third measurement is 3.3 volts and the measurement it gave is 2.9 volts. I have also noticed that there is an integrated LTRA that heats up more than normal next to these measurements but I cannot find a datasheet.
I put photos
