By way of a free fall save that actually works by round balls of the steel from the sensor signals at level height (h) 0.10 0.15 0.20, 0.25, 0.30, 0.35, 0.40, 0.45, 0.50, 0.55, m, respectively.
By the way, fall freely Budget that can be used practically by the time the fall of the round steel of sensor signals at altitude (h) 0.10, 0.15, 0.20, 0.25, 0.30, 0.35, 0.40, 0.45, 0.50, 0.55 m. sequence
By way of free fall Saving can be used by matching the time falling ball steel from sensor signals at altitude (H) 0.10 0.15 0.20 0.25,,,,,,, 0.30 0.35 0.40 0.45 0.50 0.55 meters, Respectively
