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.
