(1) Arrange the instrument First arrange the theodolite on the measuring station. After centering and leveling, install the laser rangefinder host on the theodolite bracket, lock it with the connector fixing screw, and pierce the battery into the bottom of the host and fasten it. The company prompts to arrange the reflecting prism at the objective point, center and level it, and make the mirror face the host.
(2) Observe the vertical angle and the temperature is soft and well-pressed. Sight the center of the target plate with the theodolite cross-thread to measure the vertical angle α. At the same time, observe and record the temperature and the reading on the pressure gauge. Observing the vertical angle and temperature, the policy is to perform skew correction, temperature correction, and pressure correction on the slant distance measured by the rangefinder to obtain an accurate degree of distance.
(3) Ranging preparation Press the power switch key "PWR" to turn on, the host will self-check and display the originally set temperature, air pressure, and prism constant values. After self-check, it will display "good". If you modify the original set value, you can press the "TPC" key and then enter the temperature, air pressure or prism constant (usually enter one by one through the "ENT" key and numeric keys). Under normal conditions, as long as the same type of mirror is used, the prism constant will not change, but the temperature and air pressure may be different for each observation and need to be reset.
(4) Distance measurement Adjust the degree of the host's sight axis, adjust the handwheel (or theodolite degree micro-motion spiral) and the main machine's pitch micro-motion spiral, so that the rangefinder telescope can be accurately aimed at the prism center. In the "good" state, precise aiming can also be determined according to the buzzer movement. The stronger the signal, the greater the movement. The rangefinder is moved up and down, left and right, to maximize the movement of the buzzer, and precise aiming is completed. "*". Applications of laser rangefinders: Laser rangefinders are now widely used in the following fields: electricity, water conservancy, communications, environment, construction, geology, police, fire protection, explosions, navigation, railways, anti-terrorism/military, agriculture, Forestry, real estate, leisure/outdoor sports, etc.
