■
Digital filter
The A/D-converted data is moved and averaged to suppress the instability of the indicated value by this
characteristic. The number of moving averages is selectable in the range of 0 - 256. With an increasing
number, the instability of the indicated value can be suppressed, but the response to input deteriorates.

Analog filter
The input signal from the strain gauge sensor is filtered to cancel unnecessary noise components by this
low-pass filter.
The cutoff frequency is selectable in the range of 2Hz - 8Hz. With an increasing cutoff frequency, the
response accelerates, but noise components may also be displayed.

Motion detect period/ Motion detect range
Set the parameter to detect stability.
When the width of change in weight value falls below the preset range × minimum scale division, and
the state continues for the preset time or more, the weight value is regarded as stable, and the stable
status turns ON.
MD (PERIOD):
0.0 to 9.9 (sec.)
MD(RANGE):
00 to 99 (CNT)
“D” in the right picture and the range are
compared at each time of A/D conversion, and
when the preset range × minimum scale division
is exceeded, the stable status is turned OFF.
“STAB” is displayed at the upper part of the
unit display section.
The output signal “STAB” turns ON at stable-time.
* “D” is the difference between the present
weight value and the prior weight value 100ms.
■
Display frequency
Set the frequency of rewriting the display.
The frequency can be set in the range of 1 to 10 times/sec. The internal operation speed does not change.
