YPP6830 Explosion-Proof Pulse Input Rate/Totalizer
View Data Log (LOGVIEW)
The Log View menu allows on-screen browsing of the
data log points stored in the meter. Data points may
be navigated by viewing the log number, date and
time, total, or grand total amounts. A known log may
be jumped to immediately, avoiding a lengthy search
for data. All logs may be deleted with the ERASE
command, requiring confirmation.
Once the log records are displayed, use the Up and
Right arrows to change the log entry being viewed.
The Enter key changes the displayed information for
the same log.
Backlight (BAKLITE)
The Backlight menu is used to enable or disable the
backlight. This feature is particularly important for the
battery-powered models with momentary backlight.
This feature is not available for models with a loop
output powered backlight.
Analog Output Calibration
(AO CAL)
This feature is only used at the factory for calibration
of the 4-20 mA analog output, if the meter has this
option. It is not recommended to access this menu
without instruction from technical support.
Backup & Restore (BACKUP)
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
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 Backup feature (load?) restores all
parameters to the programmed values stored in
backup restore memory. The Load Backup 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 41.
The Reset Defaults 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 41.
•
Once meter parameters have been saved to
memory by the backup restore feature there is no
recovering of the previously saved settings.
•
Once parameters have been loaded into the meter
from the backup restore feature there is no
recovering of the previously programmed settings.
