The held value is saved even when the measuring tool is switched off (manu-
ally or automatically). However, it is deleted when changing batteries or
when the batteries are empty.
Measuring with Leg Extension (see figures G–H)
The leg extension (21) makes it possible to measure angles when the con-
tact surface is shorter than the fold-out leg (1).
Place the base leg (4) and the leg extension flat on the surfaces to be meas-
ured.
The measured value of the angle w between the base leg and fold-out leg is
indicated in the display. The required angle v between the base leg and leg
extension is calculated as follows:
v = 180° – w
"Simple Mitre" Operating Mode
The "Simple mitre" measurement is used to calculate the cutting angle MTR
when two workpieces with the same mitre have to form any outer angle x°
smaller than 180° (e.g. for skirting boards, banister columns or picture
frames).
The "simple mitre" operating mode is activated by pressing the but-
ton MTR1 (15). The displayed value is always used for the calculation of the
MTR. If a saved value is being displayed (indicator (a) flashes), the calcula-
tion 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 skirting boards),
measure the corner angle x° by positioning 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 required angle is indicated in the display.
The mitre angle MTR, by which the two workpieces are to be shortened, is
calculated. For these mitre/bevel cuts, the saw blade is perpendicular to the
workpiece (the bevel angle is 0°).
