Setup>Tank Chart>AccuChart
This screen lets you setup the AccuChart auto
m
atic calibration feature for a tank.
Make sure the following is done before you start an AccuChart calibration:
• The tank has a chart created in Tank Profile which will be used in the AccuChart calibra-
tion.
• The dispenser
m
eters are calibrated so the syste
m
has accurate dispense
m
easure
m
ents
to use in the AccuChart calibration process.
Select any tank fro
m
the icon list on the botto
m
of the screen to enter its AccuChart settings.
Update
S
chedule
-
Describes how AccuChart calibration charts are updated and assigned to tanks Method:
Immediate
- The active chart is updated every ti
m
e AccuChart generates a chart. Because
the chart i
mm
ediately beco
m
es active, the console calculation of product volu
m
e will also
change based on the data in the newly active chart.
Charts
m
ay be created
m
ultiple ti
m
es during the calibration period, so the calculated product
volu
m
e
m
ay also change
m
ultiple ti
m
es.
If you enable AccuChart warnings, the console will post warnings if charts have not been
generated during the calibration period.
Periodic
- Select up to four target dates on which the console will activate a generated
chart. If a chart is available on one of the target dates, the console activates the chart. You
can view available charts in “Setup>Tank Chart>Charts”.
If there are
m
ultiple charts available, the console will activate the chart with the best data
sufficiency. See the Actions>Help>Diagnostic>AccuChart>Data Sufficiency topic for
m
ore
infor
m
ation.
If you enable AccuChart warnings, the console will post alar
m
s if the console has not gener-
ated any charts during the calibration period. On the final target date the console will also
post a warning if there are no new charts available for this tank.
Complete
- The last chart generated by AccuChart at the end of the calibration period
beco
m
es the active chart. Data Sufficiency is not considered; only the date the chart was
created.
If you enable AccuChart warnings, the console will post warnings if charts have not been
generated during the calibration period.
Never
- The console never auto
m
atically
m
akes an AccuChart-generated chart the active
chart for this tank.
Apply Date 1 - Date 4 Fields
[Field available only if the Update Schedule field is set to
Period
]
Touch to enter four target dates for periodic generation of an active chart by the console.
The reco
mm
ended periodic selection period is 14 days apart (for exa
m
ple, 14, 28, 42 and
56).
Calibration Period
Touch to enter the nu
m
ber of days to calibrate the tank (typ-
ically 30 - 120 days).
The calibration period depends on tank activity. A low-
throughput tank (e.g., one that has a "high test" fuel)
m
ay
require a longer calibration period than a quick-throughput
tank (e.g., one that has "regular" fuel).
NOTE
:
If, at one day prior to the end of your calibration
period selection, AccuChart has insufficient data to create a
tank chart, it posts a warning (if the Enable AccuChart Warn-
ings field below is set to Enabled), allowing you the opportu-
nity to extend the calibration period.
Days Left to Calibration Completion
[Read-only field] The nu
m
ber of days re
m
aining to co
m
plete
the calibration (after you initiate a calibration using the Start
button), including the start date of the calibration.
Exclude Days
Touch to re
m
ove specific days fro
m
the calibration period.
For exa
m
ple, you
m
ay want to exclude the days the site had
m
aintenance perfor
m
ed, such as when
m
eter calibration
occurs.
NOTE
:
If you need to exclude
m
ore than 25% of the calibra-
tion period, we reco
mm
end you stop the tank calibration.
Delete any created charts and restart the calibration.
Enable AccuChart Warnings
Touch to enable or disable AccuChart warnings. When
enabled, the syste
m
produces a warning when AccuChart
has not co
m
pleted a calibration because of insufficient data.
See Diagnostic>AccuChart>Calibration Feedback for
m
ore
infor
m
ation.
Min Operating Level%
Touch to enter the desired
m
ini
m
u
m
operating height of the
fuel (as percentage of tank dia
m
eter) for valid calibration
results. It should be greater than or equal to 10%. The
default is 10%.
Max Operating Level%
Touch to enter the desired
m
axi
m
u
m
operating height of the
fuel (as percentage of tank dia
m
eter) for valid calibration
results. It should be less than or equal to 95%. The default is
95%.
NOTE
:
The difference between the Min Operating Level% and
the Max Operating Level% should be at least 50% and should
include the
m
idpoint of the tank (50%). The 50% setting can-
not be the endpoint of the range between the Min and Max
Operating Level%. For exa
m
ple, you can enter a range of
25% to 85%, but you cannot enter a range of 5% to 50%.
Start
Touch Actions
then the Start
on the Actions popup

enu. If you select at the pro
m
pt to start the calibration, a
new AccuChart calibration is started and the following is
done:
• Sets the Start of Calibration field to the current date.
• Sets the Days Left To Calibration Co
m
pletion field to the
nu
m
ber of days in the calibration period. This field displays
in the Diagnostic > AccuChart > Data Sufficiency screen.
• Clears all AccuChart alar
