8. The Enable checkboxes may be used to suspend data collection for one or more logs. A log's
existing records will not be affected when the log is disabled. The fact that a log is disabled will be
reflected in the Log Configuration window by the presence of a red 'x' at the top of that log's item
tree. In addition, the area for that log in the bar graphic will be grayed and marked as 'Disabled'
9. Finally, click Send to Instrument to push the log configuration to the ERX350 Device. A few seconds
will be required for the transfer. A window should appear indicating 'Successfully Configured'.

4.3.2 Reading Audit Trail from the ERX350

Once audit trail logging is configured and some amount of data has been collected, it may be transferred
to the host. The process can be initiated from the Transfer menu or icon
Data window.
You must specify the number of logs to read and the amount of data to transfer. All configured and
enabled logs can be checked in the Log Selection frame. If a log is not configured it cannot be checked.
The amount of data is specified by date/time ranges. The simplest option is Since Last Download. The
host will examine its database for the most recent record for each log for this instrument and construct a
command to the ERX350 for all data it has collected since then. Using this option each time will ensure
that the host database contains a complete set of audit trail records for each log in each instrument.
There are three other options if a specific data range of data is desired.
Note: Note: Reading of audit trail records does not remove them from ERX350's memory. They can be
read any number of times until they are overwritten, as explained above.
