Four Introductions To The Application Of Laser Range Finder
Dec 12, 2018

Set up the instrument First settle the theodolite on the station. After centering and leveling, install the laser range finder on the theodolite bracket, lock it with the adapter fixing screw, insert the battery into the bottom of the main unit and fasten it. The company reminded to settle the reflective prism at the point of aim, centering and leveling, and making the mirror face toward the host. Observe the vertical angle and the temperature is smooth. Use the theodolite cross-hair to align the center of the seesaw and measure the vertical angle α. At the same time, observe and record the readings on the temperature and pressure gauge. Observe the vertical angle and the temperature is good. The goal is to perform tilt correction, temperature correction and good pressure correction on the slant range measured by the range finder to get an accurate interval.

Ranging preparation Press the power-on key “PWR” to start the machine. The host self-tests and displays the original set temperature, air pressure and prism constant values. After the self-test is passed, “good” will be displayed. If you modify the original setting value, you can press the “TPC” key to input the temperature, air pressure value or prism constant (usually input one by one through the “ENT” key and the numeric keys). Under normal conditions, only the same type of mirror is applied, the prism constant is constant, and the temperature and air pressure may be different for each observation, and need to be newly set.

Interval measurement Adjust the main axis of the main axis to adjust the handwheel (or the theodolite level micro-screw) and the host pitch micro-rotation spiral, so that the rangefinder telescope accurately targets the center of the prism. In the "good" state, accurate aiming can also be judged according to the sound of the buzzer. The stronger the signal is, the louder the sound is. The upper and lower left and right micro-range rangefinders make the sound of the buzzer the loudest, and the accurate aiming is completed. "*".

Laser range finder applications: Laser range finder has been widely used in the following areas: electricity, water, communications, environment, construction, geology, police, fire, blasting, navigation, railway, anti-terrorism / military, agriculture, forestry , real estate, leisure / outdoor sports, etc.
