"Copy" function:
– Switch the audio signal on (see "Switching the Audio Signal On/Off",
page 17).
– Press the "Hold/Copy" button 6. The current measuring value is saved.
A short beep sounds, the indicators for unit of measure f and audio signal
c flash.
– Coarsely measured values can be corrected before transferring them: To
increase the saved value, press the button for increasing the display val-
ue 4; to decrease the value, press the button for decreasing the display
value 5.
– Position the measuring tool at the target location, where the measured
value is to be transferred. As shown in the figure, the alignment of the
measuring tool is irrelevant. The alignment aids a indicate the direction
in which the measuring tool has to be moved, in order to reach the angle
to be copied. When reaching the saved value, an audio signal sounds and
the alignment aids a go out.
– Press the "Hold/Copy" button 6 again to start a new measurement.
Changing the Zero Point
For easier checking of grades (e.g. 45°), the zero point of a measurement
can be changed.
Align the measuring tool by placing it against a reference workpiece in such
a manner that the desired new zero point is displayed as the measuring val-
ue (e.g., 45.1°). Press the "Alt 0°" button 3. The measured value b and the
indicator for a changed zero point e flash.
Coarsely measured values can be corrected as long as the measured value
b flashes: To increase the saved value, press the button for increasing the
display value 4; to decrease the value, press the button for decreasing the
display value 5 (e.g. from 45.1° to 45.0°). 3 s after the last button actua-
tion, the displayed grade value is saved as the new reference value.
After the value has been saved, the flashing indicator e indicates the
changed zero point. The current measuring value, with reference to the new
zero point, is displayed in measuring indicator b; the alignment aids and the
audio signals also refer to the new zero point. Example: For a 43.8° grade
with reference to the horizontal line and a saved zero point of 45°, the value
1.2° is displayed as the measuring value.
To return to the standard zero point 0°, press either of buttons "Alt 0°" 3,
"Hold/Copy" 6 or "CAL" 4. The indicator for changed zero point e goes out.
Contact-free Measuring/Transferring of Grades
With the laser, it is possible to measure and transfer grades contact-free,
even over greater distances.
 Do not point the laser beam at persons or animals and do not look in-
to the laser beam yourself, not even from a large distance.
 Always use the centre of the laser point for marking. The size of the
laser point changes with the distance.
To measure grades, align the measuring tool in such a manner that the laser
beam runs alongside the surface to be measured. To transfer grades, align
the measuring tool in such a manner that the desired grade is displayed as
measuring value b, and mark the grade on the target surface using the laser
point.
Note: When transferring grades via laser, take into consideration that the la-
ser comes out 24 mm above the bottom edge of the measuring tool.
Please note that the laser point can deviate horizontally.
Accuracy Check and Calibration of the Measuring Tool
Checking the Measuring Accuracy
Check the accuracy of the measuring tool prior to critical measurements, af-
ter intense variations in temperature as well as after heavy impact.
Before measuring angles <45°, the accuracy check should take place on a
level and roughly horizontal surface; before measuring angles >45°, on a
level and roughly vertical surface.
Switch the measuring tool on and place it on the horizontal or vertical surface.
Select the unit of measure "°" (see "Changing the Unit of Measure
(see figure A)", page 17).
Wait for 10 s and note down the measured value.
Rotate the measuring tool by 180° around its vertical axis. Wait again for
10 s and note down the second measured value.
 Calibrate the measuring tool only when the difference between both
reading values is greater than 0.1°.
Calibrate the measuring tool in the position (vertical or horizontal), in which
the difference of the measured values has been determined.
Calibration for Horizontal Surfaces (see figure E)
The surface onto which you place the measuring tool must not deviate from
the horizontal line by more than 5°. If the deviation is greater, the calibra-
tion process is discontinued with the indication "---" .
 Switch the measuring tool on and position it on the horizontal surface
in such a manner that the spirit level 12 faces upward and the display
11 faces you. Wait for 10 s.
