Weighing Functions
If the adjustment weights and adjustment digits of a SIWAREX FTA are known
then the adjustment procedure does not have to be performed. These are simply
sent to the SIWAREX FTA with the DR3 data record and the scale is immediately
operational (after an official calibration run on the scale, sending the DR3 is no
longer possible).
The SIWATOOL FTA supports you in quickly performing an adjustment.
Possibility 1:
After commissioning and after the adjustment, all data records of the scale are
read from SIWAREX FTA and are stored as scale file ScaleX.FTA.
Identical scales can now be put into operation immediately. Connect the PC with
the new scale and activate the "Send all data records" function. This also transfers
the adjustment weights and the adjustment digits - the characteristic curve is
defined immediately. The same applies for exchanging a SIWAREX FTA of course.
Possibility 2:
Use the SIWAREX FTA - function "Theoretical Adjustment" and determine the
characteristic curve of the scale from the technical data of the load cells alone.
In that case, proper construction of the scale is necessary.
Note
Normally, defining two operation points is sufficient to determine the characteristic
curve of the scale. Other operation points must only be defined on non-linear
systems - New digital values (adjustment digits 2, 3, 4) are assigned with other
calibration weights (e.g. 70%, 80%, 100% of the measurement range).
