I’ve just completed the EDU09 kit (my first level 4 difficulty Velleman Kit).
Initially the kit failed calibrartion but this forum pointed me in the right direction (I had IC2 the wrong way round).
Now, when I connect the kit to any signal it does not respond.
The software display shows a signal but this does not correspond to the connected signal.
Could anyone offer me any advice on how to proceed and what I can do to test where I’ve gone wrong?
I can provide pictures / voltages if someone would let me know what would be useful.
Many thanks for your help.
