How to adjust the unit m of the rangefinder
Press and hold that key below the plus and minus symbols that is the one on the left side of the bottom row and continue for a few seconds to change the unit once, every time you press the Pratt & Whitney Measurement X2.
A rangefinder is an instrument designed for distance measurement based on the principles of optics, acoustics and electromagnetic waves. A rangefinder is a track projection instrument used to measure the distance to a target for track projection. Rangefinders come in many forms, usually a long cylinder consisting of an objective lens, an eyepiece, and a range turning knob to determine target distance. A laser rangefinder is an instrument that uses a laser to accurately determine the distance to a target. Laser rangefinder in the work of a very thin beam of laser light to the target, by the photoelectric element to receive the target reflected laser beam, the timer to determine the laser beam from the time of emission to the time of reception, calculated from the observer to the target distance. Laser rangefinder is currently the most widely used rangefinder, laser rangefinder can be classified as handheld laser rangefinder (measuring distance 0-300 metres), telescope laser rangefinder (measuring distance 500-3000 metres).
Measuring range
1. Measuring range increase: The measuring range of a rangefinder is usually increased when measuring in a dark environment (dawn or evening) and when the target and/or rangefinder is in the shadow of bright light. Using a target plate will also increase the rangefinder's measuring range.
2. Measuring range reduction: The measuring range may be reduced under bright conditions, for example when working in bright sunlight or under very strong lighting. The measuring range of the rangefinder may be reduced when measuring through glass or when an object is located in the path of the laser beam.
The range of the rangefinder may be reduced when measuring on green, blue or black matte surfaces or when measuring on wet or luminous surfaces.
