The instrument is compact structure, small volume, light weight, easy to carry, simple operation and have reliable precision, stable performance, etc. This instrument is to use the needle through the dial reading to determine the target bearing. At the same time, the heavy vertical type goniometer with the reading of the steering wheel Angle, slope Angle of the target can be determined.
A, use:
Occurrence:

1, the test including, inclination, inclination;
2, terrain sketch survey: including orientation (i.e., intersection point), slope Angle, set level;
3, vertical Angle measurement.


Second, the new geological compass main performance


1, magnetic damping time (needle deflection 90 ° to stay in the original position of the time) < 10 seconds
2, reading error:
A magnetic rotation before and after the indicated the degree of error of plus or minus 0.5 ° or less
B needle in 0-180 °, 90-180 ° out caused by eccentric error of plus or minus 0.5 ° or less
C goniometer error of plus or minus 0.5 ° or less degree


3, level sensitivity:
A level for 15 '+ 3' long / 2 mm
B round level of 30 '- 5' / 2 mm


4, instrument appearance, size (length x width x height) for 82 * 70 * 35 (mm)
5, product weight: 106 g


(a) occurrence measurement (, inclination, inclination)


1, the trend of the test:
To the dike on the horizontal projection direction. To measurement, the instrument cover (1) open to the limit position, start switch (4) of the needle, and adjusted the magnetic declination in the region, the instrument two long edges on the characteristics of the rock surface (representative), keep centered round bubble, the degree indicated by the magnetic North Pole is the rock.


2, measuring bias:
Direction is perpendicular to the direction to the direction of the instructions. Measuring inclination, using instruments on the short side or the back cover with the characteristics of the rock surface, make centered round bubble, the tendency indicated by the magnetic North Pole.


3, the Angle measurement:
Angle is perpendicular to the Angle to the horizontal plane Angle. Measuring Angle, open the cover to the limit position, lock the needle, make the side of the instrument is perpendicular to the direction which against the characteristics of the rock surface, press the brake torque on the reverse of the shell (the best move for 2-3 times), goniometer referring degree on the steering wheel, is the dip Angle of strata.
Because of the trend and dip Angle is 90 ° each other, so in actual measurement, the trend and tendency of the two factors, only one measurement can, in general only measure to the line.


(2) the preliminary survey
1, the orientation:
Bearing is also called the intersection point, namely the target's direction and position. Open the instrument on the cover of needle, and with his right hand clenched instruments, mirror back to observer the arm (mirror when target under the line of sight toward the arm) and against the body reduce jitter, to adjust the mirror with his left hand and rotate the body, making them into the mirror, and divide by the mirror line, sighting, pointed and the mirror line at the same time, and keep the circle center blisters, and then the degree indicated by the magnetic North Pole is the target's direction.
According to the same method, on the other side of the target measurement, this two points on the same target measured two line along the measure of the degree of intersection in the goal, it is concluded that the location of the object.


2, measuring slope Angle:


Slope Angle is by measuring point to the target connection with horizontal plane Angle. Measuring when open the cover to 90 °, lock the needle, right hand holding down instrument shell makes the sensor, and then observed after sighting pointed, depending on the hole line and target, with the right hand index finger press brake torque under the 2 to 3, then goniometer referring to the degree on the steering wheel is the slope Angle of the target.
If the instrument can direct contact with the target of slope, only to the surface against the target characteristics of the instrument, push the brake button 2 to 3, the goniometer refers to the degree, on the steering wheel is the slope Angle of the target.


3, horizontal line:
Fixed horizontal line is to determine whether two or more targets at the same horizontal plane. Measurement will cover opened to 90 °, by sighting, depending on the hole line at the target, and then press the brake torque under the 2 to 3, write down the degrees goniometer referred to. Again in the same station, same height, another goal, in the same way to measure if the goniometer degree referring to the same, suggests that the two goals in the same horizontal plane.


(3) the verticality measurement:
Open the instrument on the cover to the limit position, lock the needle, with instruments of long side depend on the object characteristics, press brake torque under the 2 to 3, and goniometer instructions of up to 90 °, then the object is vertical.


(4) as a map:
On the figure, the instrument is engraved feet side on the measuring point (or known) on the target. Rotating equipment, make the magnetic North Pole guide degree and degree of field measurements at the same time, can draw a straight line in the edge, this line is the target point in the direction of the line, the intersection of the two direction of the goal line is the target position.
