OK, the model 3007 is not displayed on their website, so I guess it's an
old model and predates the compensation trick.

As I said, it's the brand new scale that's got the problem. It's almost
certainly designed into the software because I can think of no way that
a fault could introduce behaviour like that, but I can think of why a
software designer would want to add that compensation, if he didn't
properly think through the consequences.
