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

Set the moving surface's neutral point at its trailing edge. You then measure horizontally to one side the 110 mm. Adjust the movement of the control surface so that the trailing edge is now 110 mm to one side than at the neutral point. You do the same for the other direction.

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 horizontal movement is the same as the recommended amount of throw, you have it set per the instructions. Nothing difficult at all.

For an elevator or aileron, you measure in the vertical direction.
