6.11 Checking the balance verification settings
For the adjustment, the balance must be switched over to service mode.
In the service mode the parameters of the balance can be modified.
The service parameters may not be modified, as this could damage the
balance settings.
In calibrated scales the service mode is locked individually for each switch.
To disable the access lock, destroy the seal and actuate the switch.
Attention:
After destruction of the seal the balance must be re-verified by an authorised agency
and a new verification wire/seal mark fitted before it can be reused for applications
subject to verification.
