4. Trapped pressure inside the test circuit is held through the
Stabilize step and then measured by Sprint iQ’s pressure
sensor [PS] during the Test step.
5. If the part exceeds the programmed leak tolerance
(pressure drop over time or quantified leak rate), Sprint
iQ’s display shows why the part failed and displays the
pressure loss or leak rate in user defined units of measure.
6. At the end of Test step, pressure trapped in the part is
vented to atmosphere through [V1] by opening [V2]
during the Vent step, and Sprint iQ is ready to make the
next test.
Vacuum Decay Testing
Sprint iQ can be equipped with either:
• a built-in venturi vacuum generator that produces the
negative pressure needed to leak test parts of typically
small volume (< 1 liter) which must be subjected to
vacuum up to 25 inHg/ 12.5 psig.
• an external vacuum pump capable of producing the
negative pressure needed to test parts of larger volume (>
