AccuChart Calibration Warning
Insufficient data collection rate -
Warning will be posted on days that
record fewer than 8 transactions.
More dispensing needs to occur.
Noisy data -
Warning will be posted after a calibra-
tion is generated, and the RMS Error
of the data exceeds a maximum
threshold.
Verify Meter Map.
Data too regionally concentrated -
Warning will be posted when there is
a severe imbalance in the amount of
data collected above and below the
mid-height of the tank.
Schedule more deliveries if insufficient
data in top half of tank. Schedule fewer
deliveries if insufficient data in bottom
half of tank.
Initial tank parameters suspicious -
Warning will be posted after a calibra-
tion is attempted, but optimization is
incomplete.
Manually verify tank diameter, capacity
and end shape.
Station too busy -
Warning will be posted on days that
record fewer than 2 calibration
records.
Temporarily halt dispensing to introduce
more idle periods.
Insufficient Data Collected -
Warning will be posted if data suffi-
ciency is too low on the day before
end of calibration period.
Extend the calibration period before it
expires. Alternatively let the calibration
expire and then restart calibration.
Annual Leak Test Fail Alarm
System failed an annual in-tank leak
test.
Rerun in-tank leak test. If second test
fails, call for service.
Annual Test Needed Alarm
System failed to perform an annual
test (0.1 gph [0.38 lph]) in the pro-
grammed number of days.
Schedule a 0.1 gph (0.38 lph) test.
Annual Test Needed Warning
System failed to perform an annual
test (0.1 gph [0.38 lph]) in the pro-
grammed number of days.
Schedule a 0.1 gph (0.38 lph) test.
Cold Temperature Warning
Probe temperature drops below -4°F
(-15.6°C).
Probe returns to normal operation after
probe temperature rises above 0°F (-
17.8°C).
CSLD Rate Increase Warning
An excessive amount of fluid leaked
into the tank during a test period.
Call for service following the procedures
established for your site.
Delivery Needed Warning
Product level dropped below pro-
grammed limit.
Call for a delivery.
Density Warning
The tank density is either greater than
the tank density low limit plus 1.00
KG/M
3
(0.062 LBS/FT
3
), or is less
than the tank density high limit minus
1.00 KG/M
3
(0.062 LBS/FT
3
).
Verify fluid density. Retest when product
density is within the tank density low and
high limits.
