15.3 Calibration with external weight / calibration options
Calibration with external weight should be performed if balance accuracy after internal calibration is not
satisfactory (in case of ALN/G). 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).
