With a full PTB logbook an open calibration lock cannot be closed. In this
case the PTB logbook must first be deleted (see Chap.: 3.3.1)!
2.6.3 Supplier and customer locks
The supplier and customer locks are used to protect all data which are not relevant to
calibration and which, where applicable, need to be changed by the supplier and/or
customer.
The lock function applies both to entries via the keypad as well as for access via the
interfaces. If the respective lock is locked, all attempts to set or read values are
acknowledged with an appropriate error message (see Chap.: 2.5.3).
The parameters protected under the supplier's lock are each identified with "S" in the lists
in the functional description.
All values which are not labelled, (shown with "-") cannot be changed, because they
represent, for example, measurements or constants.
The supplier and customer locks consist of an 8-figure code number.
The locks can only be changed when they themselves are open or a higher ranking lock is
open. The calibration lock has the highest priority. So with the calibration lock open,
parameters can also be changed which are subject to the supplier's lock.
