7.3.4 Measuring cylinder volume
Each step of the volume measurement operation is indi-
cated graphically in the display. To measure the volume
of a cylinder you are required to measure two distances.
For example, to determine the volume of a silo, proceed
as follows:
1. Select the Cylinder Volume function from the Areas
and Volumes application group.
2. Aim the range meter at the corresponding target to
measure the height of the cylinder.
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 next target to measure
the diameter of the cylinder.
5. Press the "Measure" button.
The second distance is measured, the volume then
calculated immediately and the result displayed in
the result line.
7.4 Trapezoid functions
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
When taking indirect measurements, make sure that all
measurements are taken in a horizontal or vertical plane.
Trapezoid functions can be used, for example, to deter-
mine the length of a roof. The Trapezoid function calcu-
lates the target distance with the aid of three measured
distances. The Trapezoid with Inclination function calcu-
lates the target distance with the aid of two measured
distances and an angle of inclination.
7.4.1 Trapezoid function (3 distances)
Each step of the Trapezoid function is indicated graphi-
cally in the display. To make use of the Trapezoid function
you require three distances. For example, to determine
the length of a roof, proceed as follows:
1. Select Trapezoid from the group of special func-
tions.
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.
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.
7. Press the "Measure" button.
The third distance is measured, the target length
then calculated immediately and the result displayed
in the result line.
7.4.2 Trapezoid with Inclination (2 distances, 1
angle)
NOTE
For accurate results, calibrate the inclination sensor be-
fore using this function.
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.
Each step when using the Trapezoid with Inclination
function is indicated graphically in the display. In order
to make use of the Trapezoid with Inclination function
you need two distances and an angle. For example, to
determine the length of a roof, proceed as follows:
1. Select Trapezoid with Inclination from the group of
special 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.
5. Press the "Measure" button.
The second distance is measured and displayed in
the intermediate result line. The angle of inclination
is measured at the same time.
The target distance is calculated immediately and
shown in the result line.
