Therefore, it is necessary to apply to the seller who sold the equipment. • Keep package in case the balance should be sent back to the factory for service.

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.
