Uson SPRINT LC - Flow Test Stabilization

Page 115
Flow Test Stabilization
Stabilize phase is not available in a flow test, so when
setting up a flow test, make sure the test time is long
enough for the product to reach a steady flow rate.
FIGURE 55
If the air pressure at the end of test time is
above the maximum pressure error value,
Sprint LC stops the test and if dump is
active, vents the air to atmosphere (Figure
55). Sprint LC displays P ERR in the
status box on the run display.
