My DS15001



I order this before the summer. Last weekend it was time to solder the kit. After turning on the Oscilloscope I see the test signal a short time then the screen was dark. The adj is connected to encoder did not work in both direction. After google about this, I was shore the small pcb. was mounted upside down with the encoder. The behaviour was different but don’t work. After checking the schematics and measuring around the encoder it was shore the PCB was broken in one track to the encoder. After a strap all run nicely. I fixed a 9V NiCad Battery and a box for that.

Here is the troubleshooting Trouble
