Backup & Restore (BACKUP)
The features are used to save and restore programmed settings. Programming can
be restored to a known saved good configuration, or to factory defaults. This is useful
to restore meters whose programming has been altered in unknown ways, or to
quickly restore known good settings if mistakes are made during reprogramming.
The save feature (SAvE?) saves all current parameter settings into the memory of the
backup restore. The backup restore feature is loaded with factory default settings
until a new configuration is saved.
The load feature (load?) restores all parameters to the programmed values stored in
backup restore memory. The load feature will not affect the current password
settings, or allow the editing of permanently locked parameters due to the enabling of
the non-resettable grand total feature. See Non-Resettable Grand Total described on
page 75.
The default feature (deflt) restores all parameters to the factory default values.
Factory default reset does not change the saved backup restore settings, override
passwords, or edit parameters locked by a permanent non-resettable grand total.
See Non-Resettable Grand Total, as described on page 75.
The meter saves all parameter settings and no reprogramming is necessary
when power is lost and restored to the meter. The total and grand totals are
saved during a power loss. Only the maximum and minimum displays are
reset when power is lost.
CAUTION
Once meter parameters have been saved to memory by the
backup restore feature there is no recovering the previously
saved settings.
Once parameters have been loaded into the meter from the
backup restore feature there is no recovering the previously
programmed settings.
