Indirect Measurements - Hilti PD-I Mode D'emploi

1. Select the Single Pythagoras function from the
group of Pythagoras functions.
2. Aim the range meter at the target.
3. Press the "Measure" button.
The first distance is measured and displayed 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.
NOTE In order to achieve accurate results, take care
to ensure that the second distance is measured at
right angles to the target distance.
5. Press the "Measure" button.
The second distance is measured and displayed in
the intermediate result line. The target distance is
immediately calculated and displayed in the result
line.
7.5.2 Double Pythagoras
Follow the symbols in the display. The blinking side of
the triangle indicates the measurement to be taken. When
the required distances have been measured, the result is
then calculated and shown in the result line.
1. Select the Double Pythagoras function from the
group of Pythagoras functions.
2. Aim the range meter at the target.
3. Press the "Measure" button.
The first distance is measured and displayed 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.
NOTE In order to achieve accurate results, take care
to ensure that the second distance is measured at
right angles to the target distance.
5. Press the "Measure" button.
The second distance is measured and displayed in
the intermediate result line.
The graphic display then automatically prompts you
to measure the third distance.
6. Aim the range meter at the target.
7. Press the "Measure" button.
The third distance is measured and displayed in the
intermediate result line.
The target distance is immediately calculated and
displayed in the result line.
7.5.3 Combined Pythagoras
Follow the symbols in the display. The blinking side of
the triangle indicates the measurement to be taken. When
the required distances have been measured, the result is
then calculated and shown in the result line.

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.
