    Anti-peak filter The transmitter has an additional filter for the elimination of sudden weight peaks (e.g. shocks or falling material). The following parameters, opportunely configured, allow you to eliminate the peak by blocking the weight for its entire duration. The weight is blocked if it remains within the number of divisions set in PK.LK.DV for the time set in PK.LK.TM and is subsequently unblocked if the weight deviates from the blocking value for a number of divisions greater than PK.DIV (o PK.bn.dv) or if the time set in PK.TIME has elapsed.
