6.Select the desired Auto Rollover type and its associated value. The data file may be automatically rolled over when it reaches a specified size, when a time interval elapses from the last rollover, or at a particular time each day.

To safeguard your data when recording in the Trend Link format, you must perform a rollover or stop logging data before your disk completely fills up. The default low disk space value of 1000K will typically be enough to safeguard your data. Use a larger value when rapidly logging large quantities of data from several instruments in the Trend Link format.

7.Click OK to return to the Data File Configuration dialog box.

8.For a Trend Link File, click Deadband from the Data File Configuration dialog box to open the Deadband Values dialog box.
