Page 23: Digital Filtering
Digital Filtering Digital filtering is used to create a stable scale reading in challenging environments. The 482-AG (firmware version 1.03 and later) allows for the selection of adaptive filtering, rolling filtering or off for no filtering. The A/D sample rate must be selected first. - Page 24 482-AG Livestock Digital Weight Indicator Adaptive Filter The adaptive filter (ADPFIL) has two settings, sensitivity and threshold The adaptive filter maintains a running average of the A/D readings when the weight change remains less than the defined threshold value. The filter automatically applies less value to each successive A/D reading the longer the weight change is less than the threshold value.
