[Rasch] Let us say that one has 10 items that have been Rasch scaled. They look like they are equally spaced. How does one test that hypothesis?

  Let us say that one has 10 items that have been Rasch scaled.  They 
look like they are equally spaced.  How does one test that hypothesis?  
Now replace those items with a tightly packed group around each of the 
10 items.  Any way to test whether the means of each are equally spaced?
