* Intro ClinoMaster Clinometers/Heightmeters
This type of hand held clinometer/heightmeter is perfect for quickly and very accurately measuring vertical angles/heights.
Typical users of this kind of instrument are: Forestors, geologists, engineers (construction, telecom), miners, architects and others who have to measure vertical angles/heights in for ex. the forest, city, quarries, mines, caves, buildings etc.
The benefits of the precision clinometers/heightmeters are:
*Very easy to read thanks to the light strong, crystal-clear scale
*Available with different angle/heightscales depending on user category
*Available with a distance prism making it easy to measure the horizontal distance to the object of whichs height is to be measured
*Available in a special Forest-version with a built-in relascope for timber volume calculation
*Quick settling-time thanks to the liquid-damped scale
Extremely accurate
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.
3. Sight with both eyes towards the top of the object.
4. Read the angle/height at the index line. Because of the optical illusion, the indexline will appear to "stand out" from the clinometers housing making it easy to very accurately read the correct angle. 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.ex. 15%
6. In this example the correct height of the object would be 70%+15%=85% x 10 metres = 8.5 metres
On models with height scales, 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.
How to use the Clino Master equipped with a
Distance Prism (DP-models)
The Clino Master-models equipped with a Distance Prism (DP) in combination with accessories Reference Standard Lath RS25 or RS50, is used for determination of the distance to the object (tree) of which the height is to be measured.
Use the number of Lath sections, according to the distance you would like to stand when measuring the objects height. (i.e. which height scale in the Clino Master you prefer to use).
Distance to object Unfolded sections
10 metres
15 metres
20 metres
25 metres
1 section
2 sections
3 sections
4 sections
i.e. every new unfolded section adds another 5 metres to the distance from the Lath.
Determination of the distance
Let us say that you are to use the 15 metre height-scale in your CM 1015/2025 LA/DP for measuring the height of a tree. Unfold 2 sections of the Lath (making a total of 3 sections visible).
1. Hang the Lath on the tree and move back a few metres.
2. Hold the ClinoMaster in your right hand and sight through the Distance Prism (situated in the corner of the aluminium body).
3. You will now see two Laths through the Distance Prism - this is an optical illusion created by the Distance Prism.
4. Adjust your distance to the tree until the two Laths seem to be edge to edge above each other. You are now at the correct distance i.e. 15 metres. (If the image of the Lath seems to be split, you are too close. If they have came apart you are too far away).
5. Sight towards the top of the tree through the ClinoMaster's sight and read the height at the 15 metre scale. Remember to add the height of the tree below the 0 meter marking in the instrument.
