TC Reference
This field lets you enter the temperature compensation (TC) Reference temperature for all volume
calculations. This temperature is determined by your location. In the U.S., the reference temperature used
to calculate TC volume is normally 60°F. In other countries, this value may differ. Canada, for example,
uses 15°C.
NOTES:
1. All leak calculations are based on the reference temperature you enter.
2. If BIR is being used and the meters reporting the sales are temperature compensated, the value
you enter must match the meters' reference temperature value. Also, in BIR setup, Temperature
Compensation must be set to Enabled.
Allowable Selection: -40 to 120°F or -40 to 48.8°C (depending on System Units selection)
Default: 60°F or 15.5°C
CSLD Evap. Reid Vap. Pressure Chart
This field appears only when the Tank Test Method selection is set to CSLD, the Climate Factor selection
is set to Extreme and the CSLD Evap. Compensation selection is set to Enabled in the Tank Setup -
Environmental Tests tab screen.
You will need to enter a Reid Vapor Pressure (RVP) value for at least 1 month of the year. The RVP
monthly values for your geographical area can be obtained from your local Petroleum Distributor.
Allowable range of valid RVP entries: 0 to 15.
Default: 00.0.
Periodic Test Needed Warning
The console monitors the amount of time since the last passed 0.2 gph (0.76 lph) tank test. By enabling
the Periodic Test Warning, you can have the system provide a warning when a tank test has not been
passed, or conducted, in a specified number of days (0 to 30), and activate an alarm if a test has not
been passed after a warning, or a specified number of days.
Allowable Selection: Enabled/Disabled
Default: Disabled
Days Before Periodic Warning
Allowable Selection: 0 - 30
Default: 25 days
Days Before Periodic Alarm
Allowable Selection: 0 - 30
Default: 30 days
Annual Test Needed Warning
The console monitors the amount of time since the last passed 0.1 gph (0.38 lph) tank test. By enabling
Annual Test Warning, you can have the system provide a warning when a 0.1 gph (0.38 lph) tank test has
not been passed or conducted in a specified number of days (0 - 365) and activate an alarm if a test has
not been passed after a warning, or a specified number of days.
Allowable Selection: Enabled/Disabled
