Note: an already processed PLU cannot be modified, if its bound process (see
below) has not been previously closed.
2.3
Carrying a Product Dynamic Calibration Out
Before processing a new PLU, the operation of DYNAMIC CALIBRATION needs
to be carried out. It is a learning process through which the machine compensates
the lack of accuracy inherent in the mechanic detection system of the item in
motion.
To carry a dynamic calibration of a product out, follow the procedure below:
Access the “ARCHIVES” menu
Access the “PLU” menu
Select the product object of dynamic calibration. If the product has not been
created yet, create the product as in the previous item.
Press “CALIBRATION DYNAMIC”.
Enter the product actual weight and confirm pressing ENTER
Now the instrument starts the conveying system and shows a red writing in the
path area meaning the number of detections to go to go through with the
operation.
Let the product pass the needed times. If once while passing by the product
cannot be weighed, the number of detections to go does not decrement.
At the end of the operation, the dynamic calibration value is stored in the selected
PLU and opening the “CTRL” parameters under item “CALIBRATION DYNAMIC”.
The procedure can be deleted anytime tapping “STOP. CALIBRAT.”.
In the moment of dynamic calibration, the parameters which variation interval can
limit the validity of the dynamic calibration value are stored in the PLU.
In particular, NOMINAL WEIGHT and TEMPERATURE are stored.
At the beginning of a process, the machine carries a check out to make sure the
current value of said parameters is between the validity interval of dynamic
calibration. If it is not, the PLU process is prevented and the dynamic calibration
procedure is required again.
For new PLUs the dynamic calibration procedure is always required.
Note: it is also possible to execute again the dynamic calibration procedure on a
PLU already processed, with a bound process; the process is updated with the
new value of dynamic calibration. In this case, as it is not possible to access the
PLU, the new dynamic calibration value can be read only accessing the area
“MODIFY DATA” from the process page.
