I just got this kit in and put it together. When I power it up it boots normally. It has firmware version 113-13801-046. The test wave shows 36-46 vpp and a duty cycle of 50%. The frequency is correct. Here are the rest of the stats:
Vmax : ~20
Vmin : ~-18
Vavr : ~1
I wiggle the sen1 and sen2 switch and the wave clears up a bit but still over voltage. I have checked the solder joints and all are good and clean.
