- The target is sighted with the reticle.
- A laser pulse is transmitted exactly along the line of sight when the measuring button is pressed.
- A highly precise stop watch begins timing at the same moment.
- The laser beam hits the object and is reflected.
- A portion of the reflected light is received by the objective lens and separated from the normal, visual beam path by a beam splitter.
- This laser light is then focused on the receiver diode.
- The timer stops when the signal arrives there.
- The microprocessor determines the range based on the elapsed time between sending and receiving the beam (light speed = 300,000 km/sec).
- The result of the measurement = the object distance is displayed within max. 0.5 sec after pressing the button.
- After 3 sec the display switch off and the next measurement can start.
