Tank Testing Requirements
Static Tank Testing is available only if the option for Tank Testing is enabled. This option can be ordered when purchasing
the console or after initial purchase by using the part number TS-TT. The software option includes both Static and SCALD
(continuous) leak testing. For TS-5 and TS-608 consoles, Static Tank Testing is included as standard programming.
SCALD is an option.
To perform tank testing, the Tank Testing software must be enabled. To verify that the software is enabled:
Starting at the Home/Status screen, press the 1.
System Application button.
Press the Application Menu button.
2.
Press the Options button. 3.
Under Option, a Tank Testing row will appear. 4.
A “Yes” in the Enabled column indicates that
the software has been purchased and is
enabled.

Test Types
This system is designed to perform two types of static tests to comply with regulatory policies.
0.1 GPH Annual Leak Test • — Detects a rate increase or decrease of product in the tank, other than dispensing
(no testing during dispensing), at a rate greater than 0.1 gallons per hour.
0.2 GPH Monthly Leak Test • — Detects a rate increase or decrease of product in the tank, other than dispensing
(no testing during dispensing), at a rate greater than 0.2 gallons per hour.
Ideal Testing Conditions
Tank and environmental conditions play an important role in passing results. Consider the following items when
scheduling or manually forcing a static leak test:
Variable Explanation
Product Level The level in the tank must submerge at least the lowest RTD (temperature sensor) inside the probe shaft.
Temperature Stability A tank with more product inside is likely to be stable thermally and allow for higher quality results.
Time of Day
This variable ties in with temperature stability. Though not likely, product in the tank may dramatically rise
and fall in temperature from dawn to afternoon and then from dusk to night. Typically, thermal issues affect
Aboveground Storage Tanks more often than Underground Storage Tanks.
Deliveries
A period of time is required to wait without a delivery between the last delivery and testing. The time to wait
is 4 hr 9 min for a 0.2 GPH and 5 hr 18 min for a 0.1 GPH after a delivery (in accordance with third party
testing). This time will allow the product to settle. If the wait time is not observed, then the test may abort or
fail.
Dispensing If dispensing occurs during a test, that test will be aborted.
Test Time
The test should be scheduled or manually forced when the test will not exceed the maximum leak test time.
If the maximum time is surpassed, an Incomplete result is likely to occur. If scheduling or manually forcing a
test, take into account what the sites hours of operation are to avoid a dispense during testing. Doing this will
prevent aborted and incomplete tests.
