Users Manual

A Data Set is opened for each instrument in a group instrument and each data set is created by appending 1 of 25 letters in the alphabet. If more than 25 letters are required, then this message appears. To delete old Trend Link files, see "Deleting Old Trend Link Files" in Chapter 5 of this manual.

Cannot change Configuration while logging!

You tried to copy channels to an instrument that was logging.

Copy channels only to instruments that are not logging.

Cannot create data file!

You are trying to start logging into a directory that does not exist or into a "read only" file.

Correct the data file name and directory path or use File Manager to check the data file properties.

Cannot create file [File Name]!

Your output file for a conversion utility (Utilities menu) cannot be created.

Enter a valid file name and directory path for the output file.

Cannot create Trend Link Data Set directory [Directory]. Check directory permissions or free disk space.

Trend Link is unable to create the Data Set directory for your Trend Link data file.

Check that the directory permission is not set to Read-Only, check the path for your data file to make sure the directory path allows access, and verify you have sufficient disk space for the new directory.

Cannot create Trend Link Data Set dummy file [File Name]!

Trend Link is unable to create the Data Set *.set file for your Trend Link data file.

Verify that the Data Set directory permission is not set to Read-Only, check the path for your data file to make sure the directory path allows access, and verify you have sufficient disk space for the new files.
