Remove slicers in a calculate function

I have a table - Table1 with columns A, B, C,  and a measure [x] which uses a calculate function to count rows on this table, based on some conditions. I also have a second table - Table2, with columns X,Y,Z.

Now, I want to create another measure like this: 
CALCULATE (
      [x], 
      ALL(Table2),
      Table1[A] in VALUES(Table2[Z])
)


The point of ALL is to remove filters from Table2[Z], because I want these values not to be affected by the slicers. However, this query is not working and VALUES(Table2[Z]) is still being affected by the slicer!
