SILVA Clino Master
SILVA Clino Master Series represents the highest
quality on the market in precision, sensitivity,
durability and short setting time. This series has
been designed for professionals, to whom superior
accuracy and quality are the most important
arguments. E.g. Foresters, geologists, surveyors,
architects, engineers, speleologists, inspectors,
builders, contractors, explorers, defence forces etc.
Instructions for use
PICTURE A and B
Measure the height of an object using the %-scale.
1.
Place yourself at a suitable distance from the object.
For example 10 metres
2. Hold the clinometer vertically close to one of your
eyes. Because of the optical illusion, the index line
will appear to “stand out” from the clinometers
housing making it easy to accurately read the correct
angle. See fig. A
3. Sight with both eyes towards the top of the object.
4. Read the angle/height at the index line. For example
70%
5.
Remember to add the angle/height below the
horizontal line to the first reading, in order to obtain
the correct height of the object. For. example. 15%.
See fig. B
6. In this example the correct height of the object would
be 70%+15%=85% x 10 metres = 8.5 metres
7. If you stand below the object that is to be measured,
please refer to the right example in fig. B.
On models with height scales (for example CM 1015/
2025 LA), you can read out the correct height directly
from the scale on different distances from the object.
This simplifies the height measurement because no
calculation has to be made.
Direct reading of angle
The top scale in the side window, furnished with red
lubber line, is used by placing the instruments long
side along the inclined plane to be measured. The
slope angle is then read directly by the lubber line.
This is the practice in measuring, where viewing
through the lens is not possible because of lack of
space. Please note that highest accuracy is always
obtained by using the optical sighting system.
Important!
Some people who have an eye condition called
heterophoria (misalignment of the eye axis) may get
incorrect reading when reading the instrument with
both eyes open. This can be checked as follows:
Take a reading to the object with both eyes open.
Then close the other eye, and if the reading does
not change significantly, there is no heterophoria and
readings can thus be taken with both eyes open.
When there is a difference in the readings, then
keep the other eye closed and sight partly aside the
instrument housing.
