Flow Setpoints
Besides pressure error tolerance, flow testing requires two independent
setpoints for flow rates— minimum and maximum flow. To pass a flow
test, the product must be within the pressure tolerance and also within both
flow setpoints at the end of test time. Figures 52 and 53.
If both the pressure error and flow tolerance are exceeded during a test,
Sprint LC shows
P ERR in the status box because pressure error has
priority over flow tolerance.
FIGURE 56
If the air flow measured by the mass flow
sensor is below the minimum setpoint at the
end of test phase (Figure 56), Sprint LC
turns on the reject light and shows
LOW in
the status box on the run display.
If dump is active, the dump valve opens and
pressure is vented to atmosphere.
