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 You can find details here https://www.thingiverse.com/thing:4920864 |

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! Reg |

Reg --- End quote --- 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. |

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 |
