test results between a known good part and a borderline failure. If
the same part is tested repeatedly and the leak result is
inconsistent, you probably need to increase the stabilization time.
The smaller the leak, the longer the time.
Test Time
In a pressure decay test, test time is the period when Sprint iQ
takes measurements to determine the amount of pressure drop
from a stabilized pressure. The instant the test enters test phase,
Sprint iQ takes the first pressure reading and stores this value P1.
At the end of test phase, Sprint iQ takes a final reading and holds
this value as P2. The difference between P1 and P2 is the total
test pressure loss over the test time. Test time must be long
enough to distinguish between good and bad parts. The smaller
the leak the longer the time.
Vent Ti m e
Set vent to specific time or 0 for off. When active, vent opens a
valve at the end of test time to vent the product and Sprint iQ’s
test circuit. If the operator or automated equipment removes the
products and vents the pressure, then vent is generally
unnecessary (unless test pressures are more than 50 psig) and this
parameter should be set to off. Vent is valuable when multiple
tests are linked and you need to vent pressure before starting the
next step in the series. When set to auto Sprint iQ activates the
dump valve and monitors the pressure until the pressure drops
below 0.5 psig, then closes the valve to be ready for the next test.
