Its very strange. There is a bug in PI Expert design.
When I select the the output to 15 V, the following sequence ocurred (Figures 1 to 4).
I don't do anything. The software change automatically. I think they multiply by 100. In this example, when I put 15V, it was changed to 1500V.
I have installed and uninstalled the software several times and did not work.
I use W7 64-bits.
Can anyone help me?
