15.2 Calibration with external weight / calibration options
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.

.
