You don't need a throw meter. Just a ruler.

Set the moving surface's neutral point at its trailing edge. You then measure vertically the 110 mm. Adjust the movement of the control surface so that the trailing edge is now 110 mm higher than at the neutral point. You do the same for the down deflection.

Don't worry about angular deflection, don't worry about the fact that the trailing edge moves through an arc as it rotates around the hinges. Just measure the center of the trailing edge. When its verical movement is the same as the recommended amount of throw, you have it set per the instructions. Nothing difficult at all.

For a rudder, you measure horizontally.
