How to adjust the rangefinder unit m
Press and hold the key below the plus and minus signs, which is the key on the left of the bottom row, and hold for a few seconds to change the unit once, each time you press Prece X2.
The rangefinder is an instrument used for distance measurement, designed according to the principles of optics, acoustics and electromagnetic waves. A rangefinder is a dead reckoning instrument used to measure the distance to a target and perform dead reckoning. There are many forms of rangefinders, usually a long cylinder, composed of an objective lens, an eyepiece, and a rangefinder knob, used to measure the target distance. The laser rangefinder is an instrument that uses laser to accurately measure the distance of the target. When the laser range finder is working, it emits a very thin laser beam to the target, and the photoelectric element receives the laser beam reflected by the target. The timer measures the time from the launch to the reception of the laser beam, and calculates the distance from the observer to the target. Laser range finder is currently the most widely used range finder, and laser range finder can be classified into handheld laser range finder (measurement distance 0-300 meters), telescope laser range finder (measurement distance 500-3000 meters) .
Simple method of using laser range finder to measure distance
measurement mode
Distance can be measured using two different measurement modes, single measurement and continuous measurement. Continuous measurement is used to determine a given distance or length, also in difficult-to-reach locations (e.g. at corners, edges or niches, etc.).
single measurement
If the rangefinder is off, it can be switched on by pressing the ON/OFF button or the MEASURE button. If the rangefinder is turned on by pressing the "Measure" button, the laser is also enabled, so the steps described below can be omitted
Turn on the laser by pressing the "Measure" button.
Point the rangefinder at the target and press the "Measure" button.
The measured distance will be displayed in the result line within 1 second.
Continuous measurement (tracking)
During continuous measurement, the distance is updated in the result line at a rate of approximately 6 -10 measurements per second. The measurement rate depends on the reflectivity of the target surface. If the beep is enabled, continuous measurements are signaled by a beep approx. 2 -3 times per second.
the
Press and hold the Measure button for approximately 2 seconds to start continuous measurement mode.
The measurement can be stopped by pressing the "Measurement" button again.
The last valid measured value is then shown in the result line of the display.
Measuring range
1. Increased measuring range: The measuring range of the rangefinder is usually increased when measuring in dark environments (dawn or evening) and when the target and/or the rangefinder are in the shadow of bright light. Using a target board will also increase the measuring range of the rangefinder.
2. Reduced measurement range: The measurement range may be reduced in bright conditions, such as when working in bright sunlight or under extremely strong lighting. The measuring range of the rangefinder may be reduced when measuring through glass or when objects are in the path of the laser beam.
The measuring range of the rangefinder may be reduced when measuring on green, blue or black matte surfaces, or on wet or shiny surfaces.
