levelling device AC-2s Nikon

Including devices primary used to align the positioning level of water (Water Level) is by the ancient Iranians to be. This alignment with. the tube of the straw has been that the middle of it hole and per head it Hole small, attached to a rope will. Two people each head, the rope on a piece of wooden graded keep saying, then people in third bowl from the middle hole with water Reed fall down, if the water from each of the holes of the two head to the extent of inequality and women to wear perfume, head tanabi that more high was located, so the bottom of the  to  identical from the two head drain . The size of the head the wood and place the rope height difference between the two was spot on.Day of the alignment of the glass that holds the bubble was use was . In other countries the alignment of the glass has a curvature, a certain was, that in the event of horizontal, being the balance of the bubble perfectly in the middle of the alignment of the incident . In later years, the ... factory, manufacturer, fixtures, mapping, embedding one or two numbers align on the side of the camera, it possible to provide believed that when the bubbles align in the middle is the axis of the cue on the camera is also horizontal crafted. Thus, by moving the side axis, the sign on a horizontal surface in space is created. With the help of this axis height difference between two points the measurement is. Thus, alignment of the optics(Optical Level) was produced. The balance on the tripod, and install with three screws set the axis indication on the camera for horizontal incident and move side camera-page horizontal in the space made was.Devices leveling  just to be able to create a square, horizontal, in space were, and to determine the elevation difference of the points from the pieces, graded the wood that the same indicators are used was.Adding a page, a graded horizontal to the camera, the possibility of measuring the horizontal angles between the two stretches on the ground to this vehicle was added. (Source the book the basics of mapping - Avalanche Saint NIA)is a device leveling  (new) from a few part has been formed: telescope alignment page calibrate the angle of the horizontal screw set  Compressor( in some models), the company Nikon is one of the Japanese companies leading in the field of equipment for optical mapping is. Equipment produced by the company in this regard include total sations mapping, etc. leveling  automatic, and a variety of other accessories. leveling  manufacturing the company because of the build quality high and accurate performance in different weather conditions, etc. a special place between engineers of these disciplines is allocated. leveling  model AC-2s is one of the leveling bestsellers of this company. This leveling  weight very stylistic and have the user very easily there. In this leveling  of the system, Mira represents the magnetic Compressor used that move very psychological in-line alignment to the existence of zaps. Slow motion in the direction of the horizontal axis in this leveling  by two screws to The Shape of the Infinite takes place that causes the  accurate on the target to form a very calm and precise in both directions possible to be. This leveling  against moisture forecast is also resistant well and can also be used in climate wet are used. At least the suffering visible in this leveling  75 cm, which makes it in venues small and compact, also it can be used. The direction of observation of the bubbles balance The leveling  a mirror has been put together so that the user clearly grasping from behind the camera, alignment of the device self-control.
