Working Instructions

Measuring of Angles (See Figure D)
Place both legs flat on the surfaces and read
the angle. The interior angle w between the
base leg 6 and the folding leg 2 is meas-
ured.
Note: Contact surfaces and contact edges
must be clean. Dirt particles lead to errone-
ous measurements.
The angles are displayed on the front and
back side for optimum readability.
The angle set is displayed until the legs are
moved with respect to each other.
If the angle displayed cannot be read directly
(e.g., when working overhead), the possibility
exists for retaining the angle displayed by
pressing the HOLD button 5 . The hold mode
is confirmed by the blinking of the hold
indicator g . The display does not change
even when the legs are moved with respect to
each other. Renewed pressing of the button
5 frees the display again.
Transferring of Angles (See Figure D)
Place the contact edges of the unit on the
workpiece and display the measured angle.
Note: If the hold modus is activated, leave it
by pressing the HOLD button 5 . Take care
that the measured angle does not change;
measure again, if necessary.

Using the Leg Extension (Accessory)

The leg extension serves for angle measure-
ment when the contact surface is shorter than
the length of the leg.
Slide the leg extension 14 from the end onto
the folding leg 2 (observe the arrow on the
extension). Extend the leg extension as far as
necessary over the joint of the angle measur-
ing device, however not beyond the stop (see
Figure A ).
For the measurement, the interior angle w is
displayed (see Figure H ). The angle v to be
measured can be calculated as follows:
v = 180° – w
Figure G shows the angle measurement of a
roof construction.
Figure H shows the angle measurement on a
stairway step.
Figure I shows the angle measurement of a
ventilation shaft that is to be covered.
Figure K shows the angle measurement of a
roof window.
