Centering 4.2.1. Centering built optical projector - Tripod settled over the ground point. - The appliance is leveled in the circular level by screws (21). - Optical projector focuses on the eyepiece grid by rotating the eyepiece (20) and on the ground point by turning the eyepiece tube. - Adjust the network ground point as: - The appliance is leveled fine. - The unit is moved in the tray (28) Tripod: 1. in the direction of the two lifting screws 2. in the direction of the third lift screw - In need again leveled. - Check the accuracy of centering in rotation of 180 °. 4.2.2. Centering using a plumb - Repeat the establishment of t. 4.2.1. - It is roughly centered by the tripod legs. - Fine centering is done by moving the tray 28 Centering over the ground point does not depend on leveling the unit. 4.3. Leveling the appliance - Adjust the roughly circular level by screws (21). - Cylindrical vial is placed along the two screws and lifting Turn them by leveling. - The upper part of the device is rotated 90 ° and the level is adjusted to the third screw (bubble moves in the direction of movement of the pointer on the right hand). 4.4. Lighting By rotating and tilting the illuminating mirror (16) is looking for optimal lighting of the rocks. 4.5. Adjusting the contrast of strokes - Direct a telescope at the sky or illuminated white sheet placed angled front of the lens. - Rotates the eyepiece (8) of the telescope until the contrast of strokes. - Remembers settings including to assist in re-work. - Focuses observed object through the ring (9) and the subject must .Shrihite be equally sharp and no parallax. - By turning the eyepiece of the microscope (7) adjusts the contrast of the rocks. 4.6. Endorse - Exempt clamping levers horizontal and vertical movement (31.33). - By collimator (4) is directed roughly telescope. - Fixed to the clamping levers (31,33) They can move separately, but more preferably are together. - It refers to the object by means of micrometer screws horizontal and vertical guidance (29,30). (The last turn of the screw Horizontal movement going clockwise, and screw height c opposite direction). 4.7. Readings on the horizontal and vertical scale In the lower part of the visual field into account the horizontal scale (Hz), and in upper-scale on the vertical (V). Objectives angular units (cities) are reported in this division of the scale, which is located within the fine reporting scale. Hundredth part of the city are reported at fine scale serves as a pointer touches of rough rock. Fractions of the division in the fine scale is estimated to eye. Example reader (Figure 3): V=291,860 gon Hz=372,080 gon Figure.3 To avoid confusion the vertical and horizontal scale are different in color. When measuring only the horizontal edges the vertical scale can be turned off by the handle (32). Errors of parallax, eccentricity of rocks and others. removed by measuring at two positions of the telescope. (After the displacement of several divisions and re-targeting). 4.8. Setting the horizontal scale By pressing the lever (12) creates a connection to the horizontal scale with the upper unit .Then when rotating the top spin and scale and the reading remains constant. By gently pressing the locking lever (11) in the direction of the vertical axis that connection razedinyava.Kogato this option is not used, the compound must be disconnected. Gently press and release the lever and do not apply lateral force! 4.8.1.1. Establish Baseline - Pressed a lever (11) rotates the upper part of the device until a required reading on the scale. - Tighten the lever (31) to rotate. - With a handle (30) finely adjusts the requested indication. - Tighten the lever (12). - Release the lever (31) and refers to the target. - Release the lever again the anchor (12). - Check the sighting and readings on the scale. Fixing in the desired values of indication chosen direction (eg. after orientation compass) eases the work and reduces errors 4.8.1.2. Re-measurement of angles In the re-measurement of angles achieves higher accuracy. - In what is position of the scale refers to the left target point and makes accurate reporting on the scale (and reading). The angle is: A1 = a1- a0 - Tighten the lever (12). - Again referring to the left point (in this indication remains a1). - Push the latch lever (11) and refers to the right point (reading a2ne account). - Repeat the operation for values a3, a4 .... an After an displacements in one direction makes accurate reporting on the scale after targeting the right point. - Calculate the mean: An= . - Release the lever (12) and the telescope is transferred through the zenith. - Targeting the right point. - Reported at the horizontal scale. - The reading differs from the previous example of 180 °, or 200grad. - Determine Al and calculate the average: А= A 1 - the actual angle A r - angle obtained after repeated measurements right Al - angle obtained after repeated measurements left A - angle value after indirect measurement To reach the average accuracy of the device 1 "(0,3 mgrad) e enough triplicate in one direction. 4.9. Measuring distances by rangefinder scale The eyepiece scale urada inflicted rangefinder strokes (Figure 4) to measure distances using vertical or horizontal rack. - Record the section of the strip l between longitudinal touches. - The horizontal distance from the point in which stands the unit to the rack is: S = 100.l.sin v. - For horizontal rack of the formula is: S = 100.l.sin v, where v is the zenith angle of reporting on the vertical scale.
