The held value is saved even when the anglefinder/digital
level is switched off (manually or automatically). How-
ever, it is deleted when changing batteries or when the
batteries are empty.
Measuring with Leg Extension (see figures G–H)
The leg extension 21 enables angle measurement when
the contact surface is shorter than the fold-out leg 1.
Place the base leg 4 and the leg extension flat on or
against the edges to be measured.
The reading of the angle w between base leg and fold-out
leg is indicated in the display. The required angle v be-
tween base leg and leg extension is calculated as follows:
v = 180° – w
"Simple Miter"Operating Mode
The "Simple MTR" operating mode is used to determine
miter angles for miter cuts that are made with the blade
vertically perpendicular to the workpiece; in other words,
miter cuts for which the bevel setting is set at 0°. Such
applications include mitering baseboard and chair rail,
picture rails, door frames, staircase balusters, and pic-
ture
The "Simple Miter" operating mode is activated by press-
ing the "MTR1" button. The displayed value is always
used for the calculation of the "MTR". If a saved value
is being displayed (indicator a flashes), the calculation
will be performed with the saved value regardless of the
position of the legs.
When workpieces are to be fitted into a corner (e.g. for
floor trimmings), measure the corner angle x° by applying
the fold-out leg and the base leg. For given angles (e.g.
picture frames), open the fold-out leg and the base leg
until the desired angle is indicated in the display.
