are high enough to cause possible injury to operators who unload
the product by hand.
7. Press the NEXT keypad to highlight Max Burst. Maximum burst is
the high setpoint Sprint LC uses to decide whether the test was a
pass or fail. Use the INCREMENT and DECREMENT keypads to set the
value for maximum burst pressure.
8. Press the NEXT keypad to highlight Min Burst. Minimum burst is
the low setpoint Sprint LC uses to decide whether the test was a
pass or fail. Use the INCREMENT and DECREMENT keypads to set the
value for the minimum burst pressure. The minimum burst
pressure cannot be set higher than the maximum burst pressure
setpoint.
9. Press the NEXT keypad to highlight Burst Event. Burst event is the
minimum pressure drop the product must cause from the peak
pressure value to have Sprint LC determine that a burst occurred.
10. Press the ENTER/BACK keypad to highlight Next Program. Use the
INCREMENT and DECREMENT keypads to set the number of the next
program to link. If not linking to another program, set the next
program to zero.
11. Press the ENTER/BACK keypad when everything is set up and ready.
After pressing ENTER/BACK, Sprint LC returns to the setup menu.
12. Turn the LOCKOUT keyswitch to run position, attach a product to
the test port, then start the burst test. Adjust the flow control on the
back panel to set the ramp rate. The pressure should increase
slowly enough for Sprint LC to catch the burst even before test
time ends, yet not so slowly that throughput is affected.
