Appendix B
Fast Fill
The Sprint LC tester described in this Appendix has an extra valve and
regulator to help fill the part quickly. They can also be used to fill the part
to a higher pressure to stress the part or to help reduce the stabilize time.
The fast fill option is typically used on
larger parts that require more time to
fill and stabilize. The new regulator is
typically a small SMC brand regulator
mounted on the air input port on the
back of Sprint LC. A Fast Fill timer is
added to the Test Params sub-
parameter menu before the Fill Time.
See page 47 in the Sprint LC Owners
Guide concerning the Test Params sub-
parameter menu.

Fast Fill Setup
A higher pressure is set with the fast fill regulator and time is set in the
Fast Fill phase to fill the part more quickly. The time is limited so that the
timer runs out as the pressure gets close to the set test pressure. Care
should be taken not damage a part with too much pressure. During the fill
time the standard pressure regulator finishes filling the test pressure to the
set value.
Over Pressure Setup
A higher pressure can also be used to stress the test part or to reduce the
time it takes to stabilize the test pressure. In this case the time is extended
long enough to reach the full pressure set by the fast fill regulator. In the
fill time the standard regulator then vents the excess pressure to
get to the test pressure.
