The timers shown in the settings menu will vary according to the test type. Refer to the test type setup
section for details on each specific test type. This example is for Pressure Decay or Vacuum Decay.
Fast Fill
: (Option) Fast fill allows the device under test to be filled via a second regulated source,
typically at a higher pressure for increase air volume. The time can be used in two ways. If
‘
Timed
’
is
selected the pneumatic output will open for set amount of time. If
‘Auto’
is selected the pneumatic
output will open until the
‘
F Fill
’
Pressure is achieved, or the timer has finished.
Note: If Fast Fill is not installed, set the timer and F Fill Press
to ‘0’
Fill
: The amount of time the pneumatic outputs will be active to fill the test part with regulated pressure
Settle
: The amount of time after the pneumatic outputs have isolated the test part from any incoming
pressure.
Note: This time should be utilized to stabilize the pressure from the temperature effects and expansion
of the part.
Test
: This timer is the amount of time set to observe for decay in pressure. The decay in this step will
be evaluated against the test limits to determine Pass/Fail of the test.
Leak Standard
: (Option) Units equipped with the secondary leak standard port can select this box in
order to include the standard during the test (self-test).
Vent
: The
’Vent’ timer
is used to relieve pressure on the part prior to the operator removing it from the
tester. Selecting ‘Timed’
will vent the pressure for the specifie
d amount of time. Selecting ‘Auto’
will
release the pressure to a safe limit (0.5psi typical). Once the pressure is released, the test is concluded.
