than direct distance measurement. Depending on application,
greater measuring errors are possible than with direct distance
measurement. To improve the measuring accuracy, we recommend
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).

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.

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 measure distance "1" as
for a length measurement.
