CMD SCALER MD4 Error Log

My guess is that you have a channel named CMD SCALER in your application and that you have a multi vector object in the logic of that channel that is triggering this error.

The multi vector need to go from smallest input to highest, there is a check stopping you from entering it wrong.

But if you are using other channels/parameters as input for the vector the values can then be dynamic and we can not check if the channel you are using as the input can be lower or higher then the next/previous values in the vector.

So you can end up with a invalid argument error.

On page 111 of the IQANdesign instruction book you have a description for this error.
