14.5 Function for 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 centre or notified body.
In legally verified balances 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. Therefore,
balance calibration causes lost of legal verification and, in consequence, the
necessity of renew legal verification in the nearest notified body or in place where
the balance is used.
Before proceeding with calibration of legally verified balance, adjustment switch
should be set to
ON
position using thin screwdriver (the balance will display the
message
Calibration switch ON!
and generate a sound). When calibration process,
described on next page, is finished, the balance will display the message
Calibration switch ON!
. Adjustment switch should be set to
OFF
position using
thin screwdriver (the balance will move to weighing).
