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
The system checks whether the geometric relationship
allows a result to be calculated. An invalid result, caused
by inadequate geometric conditions, is indicated by a
warning triangle in the result line. In this case, one or
more of the distances must be remeasured.
NOTE
When taking indirect measurements, make sure that all
measurements are taken in a horizontal or vertical plane.
A distance can be measured indirectly by taking sev-
eral measurements and the result then calculated using
the Pythagoras rule. The Single Pythagoras method uses
a triangle with two measured distances. The Double
Pythagoras method uses two adjoining triangles. The
Combined Pythagoras method uses the differential be-
tween two triangles.

7.5.1 Single 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 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.
1. Select the Combined 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.
