AuditTrail Log
Function
AutoComplete
The “AutoComplete” function facilitates the input of the user name. You only
have to enter so many letters as the analyzer requires to identify the name.
This function can be switched off in the AuditTrail menu because the automatic
display of the user name reduces system security, which then might not be
sufficient for FDA documentation.
Accessing the diag menu
To protect all data against unauthorized query, it is also possible to protect the
diagnostics level with a passcode (this will also affect the Favorites menu).
As delivered, access to the diagnostics level is free.
AuditTrail log
The AuditTrail log is an additional – protected if required – recording of all data
on the AuditTrail card (SmartMedia card). The log is recorded in the currently
selected language.
The data can be encrypted (to protect against unauthorized query) and
secured with a checksum (to prove the authenticity of the data). The encryption
can be switched on or off in the AuditTrail menu of the Administrator level.
A four-digit line numbering (0000 ... 9999 P 0000 ..., cyclic) ensures uninter-
rupted recording. The audit trail log cannot be deleted by the Protos.
A buffer storage is provided to store the recorded data while the AuditTrail card
is being replaced, for example. An error message "Fail AuditTrail card" is gener-
ated when the buffer is full. The oldest entries in the buffer will be recorded.
They are then missing in the log (the corresponding line numbers will be
missing).
When an empty AuditTrail card is inserted, the buffer storage and the current
entries are transferred to the empty card.
