Indirect Measurements - Hilti PD-E Manual De Instrucciones

4. Aim the range meter at the target.
5. Press the "Measure" button.
The second distance is measured and displayed in
the intermediate result line.
6. Aim the range meter at the target.
NOTE In order to achieve accurate results, take care
to ensure that the third distance is measured at right
angles to the target distance.
7. Press the "Measure" button.
The third distance is measured and displayed in
the intermediate result line. The target distance is
calculated immediately and shown in the result line.

7.6 Indirect measurements

NOTE
A reduced level of accuracy, much lower than the level
of accuracy of the tool itself, must generally be expected
when the indirect measuring method is used. In order to
obtain the best results, care must be taken regarding the
geometry of the situation (i.e. right angles and triangle
relationships). Best results are obtained when the tool
is aimed carefully at the corners of the object, when all
points are within the same plane and when the measure-
ments are taken from a location not too far away from
the object.
NOTE
For accurate results, calibrate the inclination sensor be-
fore using these functions.
NOTE
When measuring an inclination, do not tilt the tool to
the side. To avoid measuring errors when tilted, the
corresponding warning is shown in the display and the
measurement cannot be taken.
NOTE
When taking indirect measurements, make sure that all
measurements are taken in a horizontal or vertical plane.
Indirect measurements can be used to determine dis-
tances that cannot be measured directly. There are sev-
eral ways in which distances can be measured indirectly.
7.6.1 Indirect Horizontal Distance (1 angle, 1
distance)
This function is particularly useful in situations where
a horizontal distance requires to be measured but the
target is obstructed by an obstacle. Follow the graphical
display, which indicates the distance to be measured.
After measuring the necessary distance and angle, the
result is calculated and shown in the result line.
1. Select the Indirect Horizontal Distance function from
the Indirect Measurement group.
2. Aim the range meter at the target.
3. Press the "Measure" button.
The distance and angle of inclination are measured
and shown in the intermediate result line.
The target distance is calculated immediately and
shown in the result line.
7.6.2 Indirect Vertical Distance (2 angles, 2
distances)
This function is particularly useful in situations where a
vertical distance on a wall requires to be measured but
no direct access to the wall is possible (e.g. floor to floor
height on the facade of a building). Follow the graphical
display, which indicates the distances to be measured.
After measuring the two distances necessary and the
angles of inclination, the result is calculated and shown
in the result line.
1. Select the Indirect Vertical Distance function from
the Indirect Measurement group.
2. Aim the range meter at the target.
3. Press the "Measure" button.
The first distance and angle are measured and
shown in the intermediate result line.
The graphic display then automatically prompts you
to measure the second distance.
4. Aim the range meter at the target.
5. Press the "Measure" button.
The distance and angle of inclination are measured
and shown in the intermediate result line.
The target distance is calculated immediately and
shown in the result line.
7.6.3 Indirect Measurement on Ceilings (2 angles, 2
distances)
NOTE
Take care to ensure that the measured points and the
point at which the tool is positioned all lie on the same
vertical plane.
This function is particularly suitable for use in situations
where a distance on a ceiling requires to be measured.
Follow the graphical display, which indicates the dis-
tances to be measured. After measuring the two dis-
tances necessary and the angles of inclination, the result
is calculated and shown in the result line.
1. Select the Indirect Measurement on Ceilings func-
tion from the Indirect Measurement group.
2. Aim the range meter at the target.
