5-6. Motion detect
Parameters are set to detect stability.
Indicated values are deemed stable if the difference between the current indicated value and the
indicated value before 100 msec become the set range or less, and if this condition continues for the
set period of time or longer.
When stability is detected, a moving average filter* will be automatically inserted to reduce
fluctuation of weight values. The setting of this moving average filter at the time of stability is
different from the setting of the moving average filter in operation mode.
*: The number of times will change according to the sampling rate.
● Setting sample
Motion detect (time) 0.8 sec.
Motion detect (range) 10 scales (min. scale unit)
When d

< set range (10 scales) continues successively for the set period of time (0.8 sec.) or longer
(d
1
< 10 and d
2
< 10 and ... and d
8
<10), it is considered stable.

- Stability/instability is closely related to HI/LO limit.
Refer to P.47 “6-3.HI/LO limit comparison mode” for details.
- When motion detect time is 0.0 sec. and motion detect range is 00 scale, the
moving average filter at the time of stability is always OFF.
