5-4. Motion Detection (MD)
MD(Motion detection)evaluates stability of weight reading and set a value to
the criteria parameter accordingly. When weight reading remains within a
specified range for a specified period of time, the system considers the reading
stabilized and set Stable bit (10th bit of n+5 CH) to "1".
Motion detection has two operation modes: Stable mode and Checker mode.
Stable mode
Each A/D conversion data is compared with five previously acquired data (D1-
D5, see diagram below). If any one of the five difference values falls out of the
specified range, Stable bit is immediately turns off "0".
* D1 represents the weight difference between current data and the data one
52
second before.
