DT220 Users Manual version 1.a Configuration Parameters
15
Scale Parameter 1.1: A/D speed (120 samples/second)
The (optional) A/D “Load Cell Module” can operate at speeds from 30 samples/second to
960 samples/second. The default of 120 samples/second bi-polar is optimal for most
applications. Speeds of 480 and 960 are for special applications only (consult factory).
Scale Parameter 1.2: Digital Filter (12)
The digital filter removes scale vibrations and other noise signals from the weight
display. The filter range is between 0 and 20. A setting of 0 provides no filtering; a
setting of 20 provides maximum filtering. The higher the filter number, the longer the
settle time of the weight display. For example:
Filter Setting Settle Time @ 120s/s
3 0.3 sec
6 0.6 sec
9 1.2 sec
12 2.5 sec
15 5.0 sec
Use the smallest filter setting that provides satisfactory display stability.
Scale Parameter 2: Full Scale Graduations (10,000)
Enter the number of graduations at full scale. The full-scale graduations are calculated
using the count-by, decimal position, and full-scale weight.
Full Scale Graduations = Full Scale Weight / count-by.
For example, if Full Scale Weight = 600.0 and count-by = 0.2 then Full Scale
Graduations = 600.0 / 0.2 = 3000.
Scale Parameter 3: Overload Graduations (10,200)
Enter the number of graduations at which the scale is in overload status. The DT220
displays “Error: Over Weight” when the scale weight exceeds overload. For example, if
the Full Scale Graduations is 10,000 grads and the scale is rated for 2% overload, then
Overload Graduations = 10,000 + (10,000 x 0.02) = 10,200.
Scale Parameter 4.1: Count-by (1)
Enter the primary units count-by. For example, if the scale is configured for:
100 kg x 0.02kg then enter 0.02
Scale Parameter 4.2: Alternate Count-by (0.5)
Enter the alternate units count-by.
