RD-MOT

1
1 – 20

Read Motion – Defines the number of sequential samples outside the motion band for
which a reading is regarded as unstable; defined in conjunction with MOTBAND and
RD-STA parameters. When the weight is changing rapidly and exceeds the motion band
for the defined number of samples, the averaging filter is turned off.

For Legal for Trade applications RD-MOT must be set to 1 or 2 to ensure
suitable motion detection.

OVRLOA

FS

Overload. Determines the point at which the display blanks and an out-of-range error
message is displayed. Maximum legal value varies depending on local regulations.

DSPRAT

0.1SEC
0.25 SEC
0.5 SEC
0.75 SEC
1 SEC
NONE

Display rate. Sets the update rate for displayed values. Values are in seconds (SEC).

No display filtering.

SMPRAT

5HZ
10HZ
20HZ
40HZ

Sample rate. Selects measurement rate, in samples per second, of the analog-to-digital
converter. Lower sample rate values provide greater signal noise immunity.

DIGFIL

ON
OFF

Enables or disables the Adaptive Digital Filtering.
The Adaptive Digital Filter averages the newest A/D value with the previous averaged
values, using a weighted average. The weighted average is based on the selected
DFSENS value, the time the system has been stable, and the amount of weight change.

DFSENS

LIGHT
MEDIUM
HEAVY

Digital Filter Sensitivity Light/Medium/Heavy is the amount of influence the current A/D
cycle has on the running averaged value. The Light setting has the most influence, so
small changes in applied load will immediately impact the displayed value.
The Heavy setting will result in an output that is much more stable and will settle more
quickly than that of the Light setting. However, small changes in weight data (on the order
of a few grads) on the scale base will not be seen as quickly. If the difference in typical
subsequent weight values on your scale will be only a few grads, use the Light setting so
the indicator will respond quickly to the applied weight. If your application is a truck scale
where the changes in subsequent weight values will be on the order of 100s of grads, the
heavy setting will be more appropriate.

DFTHRH

0 – 999999

Digital Filtering Threshold controls the response of the filter and should be set above the
noise disturbances in the system. The value entered is in display graduations. When a
new sampled weight value is acquired, the filter compares the new value to the previous
(filtered) output value. If the difference between the new value and the previous output
value is greater than the DFTHRH parameter, the filter is flushed out and the newly
acquired sample value is used. This allows the indicator to update quickly to an applied
weight change.
