Scope of application:

Applicable to the construction industry, machinery industry, geography, used to measure the level of,

Slope, direction etc..

Use:

Compass is the determination of position, level, slope, distance (pitch angle

Degree), a simple measurement of height, length and mapping simple map

Material.

Simple introduction:

A) reticle system, circumference were engraved in 300 lines, each line is 20 (close A).

With the needle, angle, pitching angle dividing unit

Degree, each line of 2.5 degrees, can measure pitch ± 60 degrees. The speedometer

Part is mainly composed of a speedometer, a measuring wheel, gear, pointer.

Mileage Table by 1:25000 1:50000 1:75000 1:100000 four

Scale scale value. The instrument side surveying and mapping rule, assessment of two points

End of the distance of 12.3 mm, assessment and collimating distance of 123 mm M.

Method of use:

Method of use: (a) the determination of position:

1, determination of local southeast northwest direction.

(1) open the compass, the direction indicator "N" alignment "0".

(2) rotating compass, magnetic north alignment refers to "0", the

When the direction is north.

Can be in the range of glass

Direct reading East, South, West, appeared in North direction.

2, the calibration map orientation:

The calibration map orientation is the use of compass makes the position on the map and the Place line.



(1) open the compass, the adjustment range, the range of index of "N"

The area of the magnetic declination. (2) to mapping and map foot the true meridian or coordinate line

(line profile is one profile) tangent.

(3) rotating the map, the northern tip of needle point "N", then the map

The range and ground range completely consistent.

3, to measure the magnetic azimuth

Magnetic bearing A. determination to target angle "

(1) open the compass, the reflector and the disc holder slightly to 45 degree.

(2) the thumb penetrates, Ping holding apparatus, by sight

The sight to the measured in targeting.



(3) in the mirror at the northern tip of the needle alignment bearing seat

(3) in the mirror at the northern tip of the needle alignment bearing seat Division of magnetic bearings, which is to target the angle value.

Magnetic azimuth determination of B. diagram of target's angle: "

(1) map with compass calibration accuracy, and maintain fixed map.

(2) the line mapping rule and the point and the target point of tangency.



(3) after the needle stationary, the northern end of the range block partition Is the magnetic azimuth point to the goal point angle value.



(two) the measurement distance 1, by directly measuring the plotting ruler distance map

Distance of 2, with the distance measurement interpret the images.

(1) the first pointer to "0"; "

(2) a hand-held instrument, the measuring wheel with care in the beginning, the measured along the road

The roll forward to the end of line.

(3) according to the pointer refers to the scale on the line, can be directly read

The corresponding distance field.

3, assessed by the distance determination device is roughly the distance of the target in the field

Instrument distance assessment two tip for the sight of the interval between and.

From 1/10, the similar triangle relationship, we aim to determine

Target distance.

(1) two known target (object) and the point distance, the two

Object (objects) the interval between the available the following formula: 

Interval = two goals between two target and standing point spacing

From the * 1/10 "

Open the instrument, aiming eye close to the sighting, two orders, such as

Standard (object) is exactly the distance assessment two tip caught.

(2) between the two and known target point and the points where the distance is 100 meters,

The two target point interval is 100 × 1/10=10 m, the

I can be calculated in this way. "In addition, the front two goals (material

Body) intervals not just distance assessment two tip

The grip, but less than or greater than the interval, may adopt the following.

Type:

Interval = two target points between two objects and the distance between the

From the * 1/10 * two goals for multiples of two tip spacing.

An example:

(1) two known target and standing point distance of 100 meters, measured

The interval between the two targets for distance assessment two tip interval 7/10,

The two inter target interval is 100 × 1/10 × 7/10=7 M. The same

Like, if the interval between the two targets for distance assessment two tip spacing

1.5 times, two inter target interval is 100 * 1/10 * 1.5=15

The two tip is the sighting, the target point and the distance between points to stand

12 × 10=120 M.
