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.
