Velleman LABPS3005DN

Hellow :sunny:

I have the following problems with the Velleman LABPS3005DN.
The Beep Sound is incredibly annoying and really loud… can I turn this thing off somehow…?
And I found a bug in the Computer software:
The diagram doesn’t update correctly.
I can set the voltage up to 32V on the supply, but the diagram freezes at 30V…
And the software only reads in the values of volts and amps every second.
When something happens in between this second it is not shown on the diagram…
I cannot set or arm/disarm OCP in the software anywhere…
And OCP needs more than half a second to kick in … whut…??
Any way to fix that myself?

greetings :v:
