DATABASE MANAGEMENT

REV. B 02/03 PN 51680-1

HUMPHREY FIELD ANALYZER II - 

i series

The Merge Database function is designed to add tests from a backup source to the tests on the

hard disk database (the destination). One disadvantage of the Restore Database function is that

it erases all the patient tests on the hard disk and replaces them with the patient tests from

the magneto-optical or backup floppy disks. If some tests are not on the magneto-optical or

backup floppy disks, these test results will be lost.

The merge database feature has the added advantage of helping prevent the loss of patient data

by the inadvertent use of an outdated or improperly labeled backup magneto-optical disk or

backup set of floppy disks. No tests are deleted from the hard drive.

Merging two databases can be a lengthy process. If your backup source contains 10,000

patient tests, it may take up to 75 minutes to merge the backup database with the current hard

drive database.

Note: If your HFA II suffered a hard disk failure that could not be repaired by the

previously described methods, you will not be given the opportunity to use the Merge

option. You will need to use the Replace procedure.

To merge a backup database with the current hard disk database:

1

 From the File Functions screen, select BACKUP/RESTORE.

2

 Choose the Source of the backup database (Magneto-optical or Floppy), and the

Destination (Hard Drive). Select PROCEED.

3

 A pop-up window will

appear giving you the

option to replace the current

hard drive database with a

backup database, or merge the

two databases.  Choose MERGE.
