If I zeroed on the speaking length, why would the arrow be up or down if it is at zero? Please explain what I am still missing here. I understand the rear angle thing, but not this. If you zero it on the speaking length, you are correct, there will be no arrow. The arrow only appears when you are non-zero... it gives you an indication of which way you are tilting away from zero. The list I gave assumed you weren't bothering to zero it out, but rather were just taking the initial speaking length reading without zeroing, and comparing that presumably non-zero number to the backscale #. Zeroing it out simplifies matters a little, but is a minor pain so I mostly don't bother. Just keep in mind if you zero it out, take note of which way the arrow points.
