failure calibrating
failure calibrating
i just finished building my scope and it powers on, touching the probe gives me a reading with my finger. when trying to use the test tone i do not get a square wave forum, i don't get any kind of wave forum what so ever and the LED does not come on to indicate triggering. what should i do or test to try and make this work?

i went through and resoldered all the small parts, IC's and such. same issue. this is what i get when i put my finger on the red lead with X1, 10mv, and ac.

Re: failure calibrating
ok i fixed it, i had the wrong settings during the calibration. i wasn't set to 0.2mv so it was all wonky. the c6 cap trim does not seem to do anything but i have a stable wave so i think I'm good to go
