is performed daily.

Where: Calculated Inventory = Opening Delivery - Metered Sales + Manual Adjustment
Physical Inventory = Fuel amount in the tank at the close of the day.
The system default is 1.00% of total meter sales (throughput) plus 130 gallons (492 litres) offset. In the
U.S. the EPA has set this default as criteria not to be exceeded. Alarm Threshold must be between 0.00
and 9.99 percent.
Allowable selections: 0.00 to 9.99
Default: 1.00
