Introduction to the functions of the German compass (see the Chinese manual for details) Pointing to the function Place the compass (compass needle) horizontally, until the bubble of the level is in the red circle, indicating that the compass (compass needle) is in a horizontal state, the green arrow in the dial is pointing to the north, the pointer in the opposite direction is pointing to the south. Positioning function Place the compass (compass needle) horizontally so that the mirror cover is perpendicular to the mirror body. Through the red line inside the lens and the dial cross scale, the two points form a straight line, that is, the object can be positioned, and the scale corresponding to the red line in the lens can be read out, that is, the target azimuth degree. Deviation Angle measurement After positioning the known object, read the azimuth degree, then move the compass (compass needle), read the azimuth degree of the target object, the difference between the two degrees is the deviation Angle. Map orientation Place the compass (compass needle) on any meridian of the map and turn the outer ring of the outer dial so that the black triangular arrow points to the north end of the map. Turn the map and the needle until the green arrow pointing north on the dial points to the center of the pointing north arrow. At this point, the map is calibrated in line with the natural geographic features. Noctilucent function Luminous function is to point to compass (compass needle) inside phosphor powder, after receiving natural light, sunlight wait for illuminate, store light energy, after stopping ray illuminate, release with fluorescent means again slowly, be in night or dark place, still can see inside short time give off light. Measuring slope Place the compass (compass needle) horizontally, open the slope plate and make it perpendicular to the pointer chassis. Release the slope pointer, and the slope pointer will change with the change of the slope. The reading degree is the slope. Maintenance and maintenance methods
1. Do not approach ferromagnetic objects, high voltage wires and electromagnetic devices when using and placing the guide needle (north), so as to avoid errors and loss of sensitivity.
