G5 Weighing Instrument

8. Maintenance

General

This chapter describes the maintenance functions when handled from the local display.

The Maintenance menu includes a number functions used for diagnostics,
maintenance and program upgrade purposes. The Maintenance menu is found under
the Main menu.

File Handling

File handling is used for copying, moving (renaming) and deleting files.

Files can be copied and moved between folders in the instrument and between a USB
memory and the instrument (both to and from the USB memory). File can be renamed
while coping or moving.

It is possible to delete files stored in the instrument and on a USB memory.

The file handling has access to the ‘user tree’ directory structure in the instrument. The
default folders are ‘InstrBackup’, ‘LogFiles’, ‘Misc’ and ‘Recipes’. The folder
‘InstrBackup’ is used as default when creating or restoring backup and the folder
‘LogFiles’ is used to store various types of log files.

If there are problems with file copy or file move it might be because of insufficient
memory. Try removing unnecessary files in the user tree.

Create Backup

Parameter values are stored in a file that can be used to restore to same or other
instruments of the same type. The user can select to save the back-up file either in the
instrument or on a connected USB memory. The file name can be edited. Note that
additional information, which is saved in the backup file, can be given before the
backup file is created.

Restore Backup

Restoring a previously stored parameter backup to the instrument. Any additional
information in the backup file is displayed before a backup file is restored. Backup files
can be fetched from internal memory or from a USB memory.

Set Default

Restore of the instrument settings to the default values that can be found in the
Technical manual. Note that default values may differs from the setting that where in
the instrument at delivery.

All Zero correction values, Levels, Setpoints, Accumulated weights, Batched weight
etc. will be set to zero when executing a default set-up.

Instrument Restart

With the Instrument Restart function it is possible to force the instrument to make
complete restart (corresponding to a power down – power up cycle). This must be used
with great caution. The user must make sure that no hazardous situation will occur.
