I'm having some troubles getting my DSO150 kit to work (official kit). I'm not sure if the kit is just broken or if my soldering is bad.
- I checked all resistors for their values and those were correct.
- I used both a 9V battery and a 9 volt DC supply.
- I did multiple VPOS alignments.
- I checked SENSEL0 - SENSEL3 readings according to the troubleshooting topic.
- I also checked AV+ and AV- and the other voltage reference points.
All readings were correct and in their acceptable ranges.
I'm a bit out of ideas and disappointed this shell is so hard to get working.
The only times the signal seems to change is when I change the resolution from 0.2V/div to 0.5/div. I.E. all voltage divisions > 0.5V look the same as 0.5V and all < 0.2V look the same as 0.2V. My rotary encoder is also not working very well, I need to push it a bit in for it to work properly. I have attached some pictures of my test signal, I hope someone can point me into the right direction. If you need anymore information please let me know.
