I believe I have gotten myself a clue about the Horvex 2, which I found today. I don't know the correct words for this but hopefully you'll understand.

With the white shield in front of the sensor you can measure the incoming light towards an object (put the meter at the object and point it at the camera), by putting the squere with to pins on it (or something) at the needle. By taking of the shield and utilizing the big arrow instead I believe you measure the reflected light, e.g. put the meter in front of the camera and point it at the object.

I have no idea if this is right, it's just a guess that seems logic.
