Measuring indirect distance
(Measurement via three distances)
With the help of this function, you can measure hard-
to-access distances (e. g. heights of exterior walls) by
linking three measureable distances via trigonometrical
functions with one another.
With the device turned on, press the button
twice to select the indirect distance measuring via
three distances. The symbol for indirect distance
measuring
flashes. Target the end and press the measuring button
MEAS
The measured value appears in the top line of the
display, while the second distance flashes. With the
laser, target the end of the next distance and press the
measuring button to measure.
The measured value is being shown on the display.
Continue with the third distance in an analogously
way. The measured value will be listed on the display.
At the same time, the resulting distance will be
calculated and listed in the bottom line.
For measuring an indirect distance, the three measured
points need to be in one line and one measurement
needs to be in a 90° angle to the measured object.
If the first or last measuring point is being seized in
a 90° angle (Ill. 5 a and b), the distance of the other
two measuring points is respectively being listed in the
bottom line of the display. If the total distance between
the first and the third point is to be measured, the
second point needs to be seized in a 90° angle. (Ill. 5c).
