How to adjust the unit m of rangefinder
Press and hold the key below the addition and subtraction symbol, that is, the key on the left of the bottom line, for several seconds, change the unit once, and press the preset X2 every time.
Rangefinder is an instrument for distance measurement, which is designed according to the principles of optics, acoustics and electromagnetism. Range finder is a kind of track calculation instrument, which is used to measure the target distance and calculate the track. There are many forms of rangefinder, usually a long cylinder, which consists of objective lens, eyepiece and ranging knob, and is used to measure the target distance. Laser rangefinder is an instrument that uses laser to accurately measure the distance of the target. When the laser rangefinder works, it emits a very fine laser beam to the target, 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 rangefinder is the most widely used rangefinder at present. Laser rangefinder can be divided into hand-held laser rangefinder (measuring distance 0-300m) and telescope laser rangefinder (measuring distance 500-300m).
Introduction to the use of hand-held laser rangefinder
1 Touch the Start/Measure key to turn on the rangefinder.
2 according to the need to add or subtract keys to change the measurement reference edge (only valid for a single measurement), a-leading edge; B-instrument support; C-trailing edge.
3 aim the laser at the target, touch the start/measure key again, and record the measured value.
4 After measurement, press the Clear key until the initial screen appears. Press the plus and minus keys at the same time to turn off the rangefinder.
When there is no working instruction for 90 seconds, the rangefinder will automatically shut down.
6 The rangefinder can be self-calibrated by using the standard distance, and can be corrected by the Offset menu item.
