6. DISTURBANCE RECORDER.
The function of the disturbance recorder is performed by a module with battery-
backed RAM memory. The memory storage capacity is sufficient for saving the last 210
records of 600 ms. When the memory is full the oldest disturbance records are
„overwritten” by the latest ones.
