reflections from all objects closer than the gating distance will be ignored. This is especially effective when ranging in unfavourable atmospheric conditions, that is, in the rain, fog, haze or in the bright sun. Gating provides better results than the “last” target selection, but it requires preliminary rough distance estimation to cut off all objects closer than the chosen one.
Note: Gating setting is remembered by the System until altered. Therefore, if you forget to turn the gating off, the next time you start measuring it can ignore the desired object, if it is closer than the gating distance. The unit will display four dashes instead of the measurement results. “Over 100 meters” display indicator shows active gating.
