Methods: (2) the same with the theodolite to measure the horizontal angle / AOB, then: 1) when the accuracy requirements are not high: Aim at the A point - set zero (0 SET) - aim at the B point, and mark the size of the roughness HR. 2) when precision requirements are high: set of observation (method) can be measured. The operating procedure is the same as the theodolite operation. When you configure the dial, press the H SET. 2, distance measurement (distance, measurement) PSM, PPM settings - ranging, coordinate measurement, before setting out. 1) the setting of the prism constant (PSM). General: PRISM=0 (the original prism), -30mm (PRISM) 2) setting up the atmospheric correction (PPM) (multiplying constant). Enter the temperature (TEMP), air pressure (PRESS), or, after calculation, enter the value of PPM. (1) function: measure the distance between HD, elevation difference VD and slant distance SD (the height difference and slant distance between the total station mirror point and the prism mirror point) Methods: (2) a prism, according to the measurement (MEAS). 3 coordinate measurement (coordinate, measurement) (1) function: it can measure the 3D coordinates of target points (X, Y, H). (2) measurement principle If input: azimuth, station coordinates (or); measured: horizontal angle and distance. There are: Azimuth： Coordinate: If input: measuring station S elevation, measured: instrument high I, prism high V, flat distance, vertical right angle, there is: Altitude： (3) methods: Input station S (X, Y, H), the instrument with high I, high V - prism aiming view B, the horizontal dial reads is set to the target point T - prism, according to the measurement to display the three-dimensional coordinates of the point T. 4, point layout (Layout) (1): according to the design of the P for setting out point coordinates in the plane position and height
