5.8.1.2 Formatting and viewing audit log records
The audit log records have neatly formatted columns for easy readability. If the record types listed in Table 15 on page 103
contain irrelevant/not applicable column values, they are represented as “---” in the corresponding record column. A typical
audit log file record appears as follows:
Rec# Date Time Source ID Name Auth Old New
1 12/11/2008 2:13:19 Meter --- Power --- --- Power-on
2 12/11/2008 2:13:22 --- 1 Alarm --- --- Tripped
Similarly, a parameter change record would appear
as follows:
Rec# Date Time Source ID Name Auth Old New
1 12/11/2008 5:11:58 1 25798 RxW width 0 1024 2048
The user may view the meter’s audit log file on the PC screen or may save it as either a text file or a Microsoft Excel file. To get
the full benefits of the Sentinel LCT8 audit trail feature, we recommend using the Microsoft Excel file option, which is available
only if Microsoft® Excel 2000 or later is installed on the PC. Additional formatting may be applied in the Microsoft Excel file for
enhanced readability.
5.8.2 Error logs
The Sentinel LCT8 error log records system error events in
a user-readable log file and stores that file in persistent
memory. The error event is also recorded in the audit log
file, whenever the meter changes from a No error state to an
error state or vice versa.
The meter can store up to 250 error event records in the
error log file. When the file size reaches this limit, any new
record will overwrite the oldest existing record in the file. This
is called a circular log , and it ensures that the user is always
viewing the 1000 most recent event records.
The error log file is not viewable on the Sentinel LCT8
display, and the contents of the file stored in the meter’s
memory cannot be altered. However, the error log file can
be downloaded to a PC using the Panametrics PanaView
SEN898 software. The log file saved to the PC opens as a text
file, and a typical error log file record appears as follows:
