6-8. Motion Detect
Setting of parameters for detecting stable measurement is required.
If the difference between the current indicated value and that of 100msec before
fall within the specified range and the status last for a specified time, indicated
values are assumed stable.
When stability is detected, the digital filter to restrain the unsteadiness of the
weight value (fixed at 128 times) is automatically inserted. This stable-time
digital filter differs from the digital filter setting in the operation mode.

dn
=
difference of indicated value 100 msec.ago
Whether the indicated value is stable or not is closely related to High
and Low Limit Comparison Mode. For details, see High and Low Limit
Comparison Mode on page 45 .
CAUTION
When the motion detect time is 0.0 sec. and the motion detect range is
00 division, the stable-time digital filter is always off.
