Supply Air
: Sprint’s standard fitting is a 1/8 inch female NPT
bulkhead. Air must be clean, dry, and free of oil. Unless
the tester is a custom, the maximum supply pressure must
not exceed 150 psig.
Test Parameter Menu
: This menu is the first menu
highlighted when the Keyswitch switch is turned to
Program mode. This is the primary menu for entering the
values that define the test and how it is to be conducted.
Target
: A pre-programmed number that Uson stores in
firmware used to calibrate Sprint iQ’s pressure and flow
sensors. The target value is matched to a pressure or flow
standard to create a lookup table for sensor linearity
adjustment.
Test Circuit
: The pneumatic tubing, fittings, valves, and
sensors that make up the internal air passages. The volume
of gas trapped inside the pressure decay test circuit is
about 6.5 cubic centimeters on the LC-PO single channel
model.
Test Cycle
: A test cycle is all Sprint-controlled testing
activities that occur from the time the START switch is
pressed to the time the operator removes the tested
product. One test cycle can have multiple tests by linking
programs in Sprint’s parameters screen. Multiple tests in
one cycle is sometimes called a test series.
Test Phases
: Each testing mode (decay, flow, and burst) has
individual phases or intervals of testing. Pressure decay
has four possible time intervals that can be set: coupling,
fill, stabilization, and test. A flow test has three phases:
coupling, fill and test. A burst test has just two possible
phases: coupling and test.
