CALIBRATION MODE *
* These functions are available ONLY for models provided with servomotor and internal
calibration mass.
The balance effects mass measurements making use of gravity (g). Differences in geographical
areas and in altitude will vary gravity acceleration (g).
Therefore, in order to have precise measurements, the balance must be adjusted to local
environment. This adjustment is accomplished by calibration function.
There are 4 calibration modes available :
1. Autocalibration
2. Internal calibration
3. External calibration
4. Technical calibration
1. AUTOCALIBRATION
The balance autocalibrates through internal calibration weight every 30 minutes, after checking by
microprocessor that other weighing operations are not being effected. In this mode, in addition to a
calibration every 30 minutes, it is possible to effect calibration with internal calibration weight by
pressing CAL key at any time, being sure there is no weight loaded on the pan.
2. INTERNAL CALIBRATION
The balance autocalibrates through internal calibration weight ONLY on user’s request by pressing
CAL key. Calibration every 30 minutes is excluded.
3. EXTERNAL CALIBRATION
The balance calibrates through external calibration weight (NOT provided on models with internal
calibration weight).
4. TECHNICAL CALIBRATION
This function allows re-storing of internal calibration weight value whenever intervention of
assistance-checking-service require it.
ATTENTION : this procedure must be effected using only calibration weight in class E2.
NOTE: for balances NOT provided with servomotor and internal calibration weight, ONLY
EXTERNAL calibration mode is available.
