How to adjust the unit of laser rangefinder m
Press and hold the key below the plus and minus symbols, which is the key on the left of the bottom row, and continue for a few seconds, change the unit once, and press Pretest X2 each time.
The rangefinder is designed according to the principles of optics, acoustics and electromagnetic waves, and is used for distance measurement. A rangefinder is a dead reckoning instrument used to measure the target distance and perform dead reckoning. There are many forms of rangefinders, usually a long cylinder, which consists of an objective lens, an eyepiece, and a ranging knob, which is used to measure the target distance. A laser rangefinder is an instrument that uses a laser to accurately measure the distance to a target. The laser rangefinder emits a very thin laser beam to the target when it is working, and the photoelectric element receives the laser beam reflected by the target. The timer measures the time from the emission to the reception of the laser beam, and calculates the distance from the observer to the target. Laser rangefinders are currently the most widely used rangefinders. Laser rangefinders can be classified into handheld laser rangefinders (measurement distance of 0-300 meters), telescope laser rangefinders (measurement distance of 500-3000 meters) .
