When you use the AngleMaster Pro, the measurements are
done with a 6" caliper set on millimeters. These readings will
equate to different angle measurements. This webpage will
help you calculate the caliper readings/settings to use for
different angles.

Elevation Angle (Angle of Inclination)
An elevation angle is between 0 and 90 degrees. It is the angle between a flat reference surface (such as a table) and the angle you're measuring. The Elevation and Obtuse angles will always add up to 180 degrees.
Obtuse Angle
An obtuse angle is between 90 and 180 degrees. This is the space that the Anglefinder tool takes up. The Elevation and Obtuse angles will always add up to 180 degrees.
Tilt Angle
A tilt angle is between 0 and 90 degrees. It is the angle between vertical and the angle you're measuring. The best example of this is the Jointmaker Pro and most tablesaws - 0 degrees is a perfectly vertical blade. The Tilt and Elevation angles will always add to 90 degrees.
