;
;
(no active
program);
-
followed by the software version (e.g.:
);
-
followed by the hardware code (e.g.:
);
-
serial number (e.g.:
);
Check that the display shows the weight and that when loading the load cells there is an increase in
weight. If there is not check and verify the connections and correct positioning of the load cells.
-
If the instrument has already been theoretical CALIBRATED (plant system identification tag
present on the instrument and on the cover: load cell’s rated data already entered):
▫
Reset to zero (see section TARE WEIGHT ZERO SETTING)
▫
Check the calibration with sample weights and correct the indicated weight if necessary (see
section REAL CALIBRATION (WITH SAMPLE WEIGHTS)).
-
If the instrument HAS NOT BEEN CALIBRATED (missing plant system identification tag)
proceed with calibration:
▫
If load cells data are unknown, follow the procedure in section REAL CALIBRATION (WITH
SAMPLE WEIGHTS)
▫
Enter the rated data of load cells following the procedure given in section THEORETICAL
CALIBRATION
▫
Reset to zero (see section TARE WEIGHT ZERO SETTING)
▫
Check the calibration with sample weights and correct the indicated weight if necessary (see
section REAL CALIBRATION (WITH SAMPLE WEIGHTS)).
-
If you use the analog output, set the desired analog output type and the full scale value (see
section ANALOG OUTPUT).
-
If you use serial communication, set the related parameters (see section SERIAL
COMMUNICATION SETTING).
-
Set instrument’s clock with current date and time (see section DATE AND TIME SETTING)
Required settings for the first batching:
-
Access the Batching Constants menu and set the minimum weight value (see section MINIMUM
WEIGHT);
-
Access the Formulas menu and set the formula 01 (see section FORMULAS PROGRAMMING);
-
Start the batching by pressing the START button or by closing the START contact.
