Pressurized Line Leak Detection
0.1 gph (0.38 lph) Line Leak Test Scheduling
•
Disabled - No manual or automatic 0.2 gph testing is allowed.
•
Repetitive - After a dispense, a 3.0 gph (11.3 lph) test is run, followed by a 0.2 gph test. The test blockout
period (selected in Precision Test Duration setup) is then observed. Following the test blockout period, the test
sequence repeats after the next dispense. This selection also enables manual 0.2 gph testing.
•
Monthly - At the beginning of every month until a test has passed. This selection also enables manual 0.2 gph
testing.
•
Manual - 0.2 gph tests run only when manually started.
Disabled is the default setting. Press STEP for Disabled, or press CHANGE to select other choices, then press
ENTER. Press STEP to continue.
0.1 gph (0.38 lph) Line Leak Test Scheduling
NOTE: The 0.1 gph Line Leak Test is an optional feature. This message will not appear unless the
0.10 Repetitive
PLLD
or
0.10 On Demand PLLD
software module key is installed in your system.
This feature allows the user to choose the scheduling frequency of the 0.1 gph tests

:
•
Disabled (default) - No manual or automatic 0.1 gph testing is allowed.
•
Repetitive -After a dispense, a 3.0 gph test is run, a 0.2 gph test is run, followed by the 0.1 gph test. The test
blockout period (selected in Precision Test Duration setup) is then observed. Following the test blockout period,
the test sequence repeats after the next dispense. This selection also enables manual 0.1 gph testing. (Note:
The Repetitive option is not available when the
0.1 On Demand PLLD
software module key is installed.)
•
Auto - 6 months after the last passed 0.1 gph test. Also enables manual 0.1 gph testing.
•
Manual - 0.1 gph tests run only when manually started.

Passive 0.1 gph Line Leak Testing
If pipe type selection was either User-Defined or APT P175SC, and the 0.1 gph line leak test scheduling selection
was Auto, the following message will appear:
Use this option if the user desires the most current passing results for 0.1 testing without increasing exposure to
false alarms.
This option does not interfere with the 6-month automatically scheduled 0.1 gph test.
1. When CSLD is available, all 0.2 gph and 0.1 gph line leak testing is subject to test blockout periods. These blockouts are imposed to allow
CSLD ‘pump off’ time to collect tank leak test data. Precision tests are run on an every other day basis. In addition, if the last precision test
result is a pass, there will be a minimum of 60 hours before the next test will be attempted. If necessary, the 60-hour blockout period can be
extended in the Precision Test Duration setup [page 5-15].
