Indirect Height Measurement; Double Indirect Height Measurement; Indirect Length Measurement - Bosch GLM 50 C Original Instructions Manual

18 | English
Note: Indirect distance measurement is always less accurate than direct distance
measurement. Depending on application, greater measuring errors are possible than
with direct distance measurement. To improve the measuring accuracy, we recom-
mend using a tripod (accessory).
The laser beam remains switched on between the individual measurements.
a) Indirect height measurement (see figure B)
Select the indirect height measurement
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 the distance "1"
as for a length measurement (displayed as a red line).
Upon completion of the measurement, the result for the sought dis-
tance "X" is displayed in the result line e. The measuring values for the
3.874 m
distance "1" and the angle "α" are displayed in the measured-value
0.0°
45.0°
lines d.
0.552 m
b) Double indirect height measurement (see figure C)
The measuring tool can indirectly measure all distances, which lie in the vertical level
of the measuring tool.
Select the double indirect height measurement
Measure distances "1" and "2" in this sequence as for a length measurement.
Upon completion of the measurement, the result for the sought dis-
tance "X" is displayed in the result line e. The measuring values for the
1.291 m
distances "1", "2" and the angle "α" are displayed in the measured-val-
0.0° 2.583 m
45.0°
ue lines d.
1.903 m
Pay attention that the reference plane of the measurement (e.g. the
rear edge of the measuring tool) remains exactly at the same location
for all individual measurements within a measuring sequence.
c) Indirect length measurement (see figure D)
Select the indirect length measurement
Pay attention that the measuring tool is positioned at the same height as the sought
measuring point. Now, tilt the measuring tool around the reference plane and meas-
ure distance "1" as for a length measurement.
