• Preset Test Pressure is the pressure you set using the
pressure regulator on Sprint iQ’s rear panel. The pressure
value is the “ideal” or target test pressure.
• Actual Test Pressure is the pressure the product is
subjected to during a test. The actual pressure could be
different from the preset test pressure due to variations in
product and small changes in the test system. For this
reason, you set the pressure error tolerance to allow for a
range of acceptable test pressure. The pressure error
tolerance is the acceptable difference between the actual
test pressure and the target test pressure.
4.1.1.3 Pressure Error
Pressure error is important because:
• it tells Sprint to stop the test if the pressure goes too far
above the preset test pressure.
• it tells Sprint to stop the test if the pressure doesn’t get
close enough to the preset test pressure.
In a pressure decay test, the pressure error is set as an equal plus
and minus tolerance around a nominal test pressure value. Enter
the number in pressure units and Sprint iQ sets both the high and
low pressure error values. Sprint iQ monitors pressure error
during the fill and stabilization phases of a pressure decay leak
test.
In a flow test, pressure error is checked at the end of test time to
allow for the necessary pressure drop caused by the flow.
