591 Backup System Setup To a DLC slave: calibration command
This command is a calibration command. This command will back up the current system
setup to any one of the two DLC slaves from the master indicator. This command goes
hand in hand with calibration command
592
.
The information included in the backup image of the system data is the calibration
information and the action tables. This command is of use in the following scenarios:
q
After a typical calibration session, it is recommended to back up the calibration and
action table information, for possible disaster recovery scenarios.
q
It might be useful to provide a user with a pre-configured DLC in the field in order to
speed up the installation process, by just issuing a restore command to configure the
system.
q
The user would like to revert to a backup due to a setup failure or corruption of system
data during installation or maintenance.
To exit this command press the [CLEAR] key.
594 Reload Scale Allocation: calibration command
This command is a calibration command. This command is typically used for field DLC
replacements. This command can be used to download the latest scale allocation to a DLC.
This is handy when performing a field replacement of a DLC unit. This command will
download the original setup to the new DLC. This command assumes that a valid
calibration and scale allocation is available to be downloaded to the new DLC. Once down
loaded the user can save the settings by exiting calibration mode -command (99).
It is important to note that the backup will be generated from the last saved calibration
and action table information as stored in the M2000D indicator
. The user should first
exit calibration mode to make sure that the information is saved to backup memory
.
The user should then enter calibration mode and issue command 591 to backup to one
of the DLC slaves in question.
All DLCs are factory calibrated to give the same counts per millivolt input for all DLC
cells. This allows the user to replace a faulty DLC in the field without having to
recalibrate the scale. The user simply install the new DLC and in calibration mode
execute command 594 to download the previously stored calibration data to the new
DLC. Exiting calibration mode (99) will save the calibration data in the new DLC
slave.
