Fine Tuning
After entering the basic parameters into a program, it is possible to fine-
tune the setup. A few tips:
If external fixtures are not being used, set coupling time to zero.
If product blows out of external fixtures, make sure a sufficiently
long coupling time is chosen.
If gross failures occur when testing a flexible product, try
increasing fill time.
Add fill and stabilize time to slow the decay rate and make it more
consistent.
If the test doesn’t need a dump valve to vent product pressure after
testing, set the dump parameter to off.
In a flow test, set test time long enough for the product under test
to fill with pressure and produce a stable flow rate.
If repeated P ERR messages show up in the status box, try
widening the pressure error tolerance or adding more fill time.
Put Sprint LC to Work
When everything is programmed and checked out, Sprint LC is ready to
work and start testing products. A few tips:
Explain controls and run display messages to operators.
Keep external connections to the product under test as straight,
rigid, and direct as possible. Flexible connections can cause
inconsistent readings.
Put Sprint LC in a place where the pressure regulator and other
controls on the back won’t get moved around or damaged.
