Programming
Sprint iQ goes into test phase only if test pressure is
within the pressure error tolerance.
6. During test time, the coupling is released and the test part
is opened to atmosphere. Sprint iQ compares the pressure
drop to the set limits. IF the pressure decay (or pressure
loss) is greater than the reject minimum at the end of test
time, the pass indicator lights up. The fail light turns on if
the pressure is less than or equal to the reject minimum.
Messages in the status box stay on until the next test.
7. If the vent parameter is set a time other than zero, the vent
valve vents the product to atmosphere. If another test is
linked to the occlusion test, Sprint iQ goes to the next
linked test in the series as long as the product passed all
tests.
8. At the end of all linked tests, the operator (or automated
machinery) removes the product and Sprint iQ is ready to
begin the next test.
Test Time Occlusion Test Pass
The product is pressurized while the clamping fixture seals the
open end of the product. The pressure drops below the reject limit
within the established test time after the sealing device opens and
allows the product to flow to atmosphere.
The significant pressure drop in the product indicates that the
product under test flows freely to atmosphere and thus is not
blocked.
Test Time Occlusion Test Fail
If the flow path were to be blocked, the product would fail
because the air loss from the product would not be enough for
pressure to drop more than the reject minimum in the test time.
Occlusion Test without Seal
The occlusion test can also be set up to work like this:
