Pressure Error
The Press. Error is set as a tolerance around a nominal test pressure value.
(Figure 41 on page 94) Enter one number in pressure units and Sprint LC
sets both the high and low pressure error values. In a pressure decay test,
Sprint LC monitors pressure error during the fill and stabilization phases
of a pressure decay leak test.
When testing, if the pressure is not within this tolerance, a reject is
indicated and P ERR is shown in the status box on the run display.
Pressure Error is a safety function to make certain that each test is
conducted within an established tolerance for test pressure.
Coupling
Coupling time is the delay provided for external devices such as
pneumatic seals or fixtures to fully activate. This gives setup personnel
added control over how the coupling valve(s) will turn on and off.
See page 60-61, and 56 for a pneumatic diagram.
To access the coupling sub-parameter menu, highlight the parameter line
called Coupling, then press the GoTo (INCREMENT) keypad to move to the
next menu and adjust coupling times. The pop-up menu for setting the
coupling time is shown on the next page.
Coupling time is the duration the valve will
be energized. Use the
INCREMENT
and
DECREMENT
keypads to enable the valve.
