Volumetric Line Leak Tests
The Volumetric Line Leak Detection (VLLD) system performs fully automatic test routines after each dispense
cycle. In addition, Volumetric Line Leak Detectors may be programmed for testing at a specified time or date.
The Line Leak Test Setup function lets you set the test method, schedule, and test rate for programmed automatic
line leak tests. Programmed tests continue to run according to the schedule you enter until you change the
parameters or disable the test.
NOTE: Line leak tests also may be started at any time from Operating Mode.
Selecting the Line Leak Test Setup Function
To select Line Leak Test Setup, press FUNCTION until you see the message:
Press STEP to continue.
Leak Test Setup Method: All Lines/Single Lines
If necessary, press STEP until you see the following message:
You can run line leak tests using the same test conditions (frequency, start time, and test rate) for all lines, or you
can establish different test conditions for each line.
To specify the same test conditions for all lines, press STEP. The system displays the following message:
To specify different test conditions for each line, press CHANGE in response to the LEAK TEST METHOD
message, so the system displays SINGLE LINE. Press ENTER and press STEP. The system now displays the
message:
Whether you choose ALL LINES or SINGLE LINE, the procedure for specifying a set of test conditions is
identical. The only difference is that the SINGLE LINE method requires you to specify multiple test conditions, one
for each line.
NOTE: The screen examples shown in this procedure assume that you have selected the ALL LINES method. If
you choose SINGLE LINE, the line number (e.g., LINE 1) appears in place of “ALL LINES” in each message.
