8 In-Tank Leak Tests
The In-Tank Leak Test Setup function allows you to establish and enter the method, timing, and duration of
automatic leak tests.
If you are using the In-Tank Leak Test feature for underground storage tank regulatory compliance, be sure the leak
test limits you establish and enter comply with the test type, accuracy, and frequency requirements as defined by
the regulatory authorities governing your site. In addition, set the in-tank leak test time for a period when no fueling
from or bulk delivery to the tank will occur. Such activity during an in-tank leak test will result in inaccurate test
results.
NOTE: In-Tank Leak tests may also be conducted, as needed, from the Operating mode.
Selecting the In-Tank Leak Test Setup Function
To select In-Tank Leak Test Setup, press FUNCTION until you see the message:
Press STEP to continue.
Leak Test Method: All Tank/Single Tank
If necessary, press STEP until you see the message:
You can choose to run In-Tank Leak Tests for all tanks simultaneously, using the same setup information, or you can
choose to set up and run leak tests for single tanks. If you choose Single Tank, you may run overlapping tests
simultaneously, even though you enter separate setup information for each tank.
NOTE: If you choose ALL TANK and plan to choose CSLD as the test frequency, then all tanks in the system must
be equipped with 0.1 gph (0.38 lph) magnetostrictive probes, and you must have the CSLD software module key
installed in this system. If you choose Single Tank, you must enter test setup information for each tank individually.
To run tests with the same setup information for all tanks, press STEP. The system displays the message:
To run tests with different setup information for each tank, press CHANGE in response to the LEAK TEST
METHOD message, so the system displays SINGLE TANK. Press ENTER and press STEP. The system now
displays:
Whether you choose ALL TANK or SINGLE TANK, the procedure for specifying setup information is almost
identical. The only difference is that the SINGLE TANK method requires you to specify multiple test setups, one for
each tank.
