Introduction to distance measurement with photoelectric distance meter
Adjust the horizontal adjustment handwheel (or theodolite horizontal micro-motion screw) of the main engine's collimating axis and the main machine's pitch micro-motion screw to make the rangefinder telescope precisely aim at the center of the prism. In the state of "good", accurate aiming can also be judged by the sound of the buzzer. The stronger the signal, the louder the sound. Move the rangefinder up, down, left, and right to make the buzzer sound the loudest, and the precise aiming is completed. "*".
After precise aiming, press the "MSR" key, the host will measure and display the slope distance corrected by temperature, air pressure and prism constant. During the measurement, if the beam is blocked or the atmosphere shakes, etc., the measurement will be interrupted temporarily, and the "*" will disappear at this time, and the automatic measurement will continue after the light intensity is normal; if the beam is interrupted for 30 seconds, the light intensity must be restored, and then press " MSR” key to retest.
The conversion from the slant distance to the horizontal distance is generally carried out on site with a range finder. The method is: press the "V/H" key and input the vertical angle value, and then press the "SHV" key to display the horizontal distance. Continuously press the "SHV" key to display the slope distance, horizontal distance and height difference in sequence
