Pressure : The relative force of a compressed air or gas.
Sprint iQ is generally configured to use PSIG, which is
the force of compressed gas relative to barometric
pressure.
Pressure Transducer : An electro-mechanical device (also
called a sensor) that converts pneumatic pressure into
electrical signals. Sprint’s pressure transducers are
rugged, accurate, repeatable, and have a very low internal
volume.
Programming : Entering values to setup the tester. Also
called setup or data entry.
Program : Data (such as test pressure, test time, and reject
levels) entered by the user and stored in nonvolatile RAM.
A program is setup in Sprint’s parameters screen. When
multiple programs are linked, the programs become a test
cycle. See also Stored Programs.
PSIG : Pounds per Square Inch Gauge. A unit of measurement
for air pressure measured with respect to local
atmospheric pressure.
PSN Ratio : Pneumatic Signal/Noise Ratio. The larger the
PSN Ratio, which is the Cal Value divided by the Comp
Value, the more repeatable the test will be. The PSN Ratio
can be in the range of .2 to .25 if +/- 10% test repeatability
is sufficient.
Ramp Up : To slowly increase pressure by routing test
pressure through the flow control valve located on the
back of Sprint. Various ramp rates can be established by
adjusting Sprint’s built-in flow control.
Reject Minimum and Reject Maximum : The amount of
pressure change allowed in a test. These values are set in
the Reject Limit menu under the Test Parameters menu.
