17.1 Scale calibration (CALIb)
Calibration with external weight should be performed if balance accuracy after internal
calibration is not satisfactory. Calibration weight stated in technical data table for the
balance (or of better accuracy) with valid verification certificate should be used then.
Calibration of legally verified balance requires violating a mark used to
protect an access to adjustment switch and results in loosing legal
verification. To renew legal verification of the balance, it is necessary to
contact a service or notified body.
In balances comply with verification
requirements performing
calibration requires changing
adjustment switch position, which is
placed behind protecting mark
(sticker) of a notified body. An
access to the switch is possible
only after removing the mark.
Before proceeding with calibration for balances comply with verification requirements,
adjustment switch should be set to ON position using thin screwdriver (the balance will
display the message Pr ON).
When calibration process, described on next page, is finished, the balance will display
the message Pr ON. Adjustment switch should be set to OFF position using thin
screwdriver (the balance will move to weighing).
