Digital Level
When the laser is turned off, the tool can also be used as a digital
level to indicate the absolute angle between the working surface
and true level.
Press the power/laser button for about 2 seconds to turn on the tool.
The laser is turned on automatically. Press the power/laser button
again for no more than 1 second to turn off the laser. Place the tool
on a working surface with the magnetic edge flat against the surface
(Fig. 10).
In this mode, the tool can be used to measure the bevel angle
between a table saw blade and the true level, by the magnetic edge
of the tool being adhered on the saw blade (ferrous metal) (Fig. 11).
