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 aides 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.

f 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.

f 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

laser comes out 24 mm above the bottom edge of the measuring tool.

Accuracy Check and Calibration of the Measuring Tool

Checking the Measuring Accuracy

Check the accuracy of the measuring tool prior to critical measurements,

after 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 sur-

face.

Select the unit of measure “°” (see “Changing the Unit of Measure”,

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.

f 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.

 Then press the calibration button “CAL” 4 for approx. 2 s until “CAL1”

briefly appears in the display. Afterwards, the measuring value flashes

in the display.

 Turn the measuring tool by 180° around the vertical axis so that the

spirit level still faces upward, but the display 11 faces away from you.

Wait for 10 s.

 Then press the calibration button “CAL” 4 again. “CAL2” is briefly in-

dicated in the display. Afterwards, the measuring value appears in the

display (no longer flashing). The measuring tool is now re-calibrated

for this supporting surface.

 After this, the measuring tool must be calibrated for the opposite sup-

porting surface. Rotate the measuring tool around the horizontal axis

in such a manner that the spirit level 12 faces downward and the dis-

play 11 faces you. Place the measuring tool on the horizontal surface.

Wait for 10 s.

 Then press the calibration button “CAL” 4 for approx. 2 s until “CAL1”

briefly appears in the display. Afterwards, the measuring value flashes

in the display.

 Turn the measuring tool 180° around the vertical axis so that the spirit

level still faces downward but the display 11 is facing away from you.

Wait for 10 s.

 Then press the calibration button “CAL” 4 again. “CAL2” is briefly in-

dicated in the display. Afterwards, the measuring value appears in the

display (no longer flashing). The measuring tool is now re-calibrated

for both horizontal supporting surfaces.

Note: If the measuring tool is not turned around the axis shown in the figure

in steps  and , then the calibration cannot be completed (“CAL2” is

not indicated in the display).
