a) Indirect height measurement (see figure B)
Select the indirect height measurement mode
Ensure that the measuring tool is at the same height as the
lower measuring point. Then tilt the measuring tool around
the reference level and measure distance 1 as for a length
measurement (displayed as a red line).
Once the measurement is complete, the result

13:20:23
for the required distance X is displayed in the
45º
37.116 m
result line (a). The measured values for dis-
45.0
tance 1 and angle α can be found in the meas-
26.245 m
ured value lines (h).
b) Double indirect height measurement (see figure C)
The measuring tool can indirectly measure all distances that
lie in the vertical level of the measuring tool. Select the
double indirect height measurement mode . Measure dis-
tances 1 and 2 in succession as for a length measurement.
Once the measurement is complete, the result
09.06.2017
13:20:23
for the required distance X is displayed in the
30º
48.873 m
result line (a). The measured values for dis-
56.335 m
35.5 º
tances 1 and 2 and angle α can be found in the
32.852 m
measured value lines (h).
Ensure that the reference level for the meas-
urement (e.g. the rear edge of the measuring tool) remains
in exactly the same place for all the individual measurements
in a single measuring process.
a) Indirect length measurement (see figure D)
Select the indirect length measurement mode
Ensure that the measuring tool is at the same height as the
required measuring point. Then tilt the measuring tool
around the reference level and measure distance 1 as for a
length measurement.
Once the measurement is complete, the result
09.06.2017
13:20:23
for the required distance X is displayed in the
60º
153.104 m
result line (a). The measured values for dis-
60.0
tance 1 and angle α can be found in the meas-
76.552 m
ured value lines (h).
d) Trapezium measurement (see figure E)
The trapezium measurement can be used to determine the
length of a roof slope, for example.
Select the trapezium measurement .
Measure distances 1, 2 and 3 in succession as for a length
measurement. Ensure that the measurement of distance 3
begins exactly at the point where distance 1 ends and that
distances 2 and 3 are at right angles to distance 1.
Once the final measurement is complete, the
09.06.2017
13:20:23
result for the required distance X is displayed
60º
3.624 m
in the result line (a). The individual measured
2.456 m
4.872 m
values can be found in the measured value
4.356 m
lines (h).
Wall area measurement (see figure F)
The wall area measurement is used to determine the sum of
multiple individual areas with a common height. In the illus-
Bosch Power Tools
trated example, the total area of several walls that have the
. same ceiling height H but different lengths L is to be determ-
ined.
Select the wall area measurement mode
Measure the ceiling height H as for a length measurement.
The measured value is displayed in the top measured-value
line. The laser remains switched on.
Then measure the length L

The area is automatically calculated and dis-

played in the result line (a). The last measured
3.899 m
12.558 m
value for length can be found in the bottom

31.395 m
measured value line (h). The laser remains
switched on.
Now measure the length L
measured value displayed in the measured value line (h) is
added to the length L
played in the middle measured value line (h)) is multiplied
by the saved height H. The total area value is displayed in the
result line (a).
You can measure any number of lengths L
automatically added and multiplied by the height H. The re-
quirement for a correct area calculation is that the first
measured length (for example the ceiling height H) is
identical for all sub-areas.
Stake out function (see figure G)
The stake out function repeatedly measures a defined length
(distance). These lengths can be transferred to a surface, for
example to enable material to be cut into pieces of equal
.
lengths or to install stud walls in a drywall construction. The
minimum adjustable length is 0.1 m and the maximum
length is 50 m.
Note: The distance from the marking is shown in the display
in the stake out function. The reference is not the edge of
the measuring tool.
Select the stake out function .
Use the button (4) [+] or the button (11) [–] to set the re-
quired length.
Begin the stake out function by pressing the measuring but-
ton (2) [ ] and slowly move away from the starting point.
The measuring tool continuously measures the
distance to the starting point. The defined
0.81x 0.500m
length and the current measured value are
0.483 m
thereby displayed. The lower or upper arrow
displays the shortest distance to the next or
1
last marking.
Note: When measuring continuously, you can set a meas-
ured value as a defined length by pressing the measuring
button (2) [ ].
The left factor specifies how many times the
defined length has already been reached. The
1x 0.500m
green arrows on either side of the display in-
0.500 m
dicate the reaching of a length for marking pur-
poses.
Red arrows or red text indicate the actual value when the ref-
erence is outside of the display.
