the valve knob fully towards the lit valve indicator LED until it reaches its stop.
Press
[ENT] when ready to proceed with the test.
Note
To abort the test but use the RPM4-E-DWT with the settings for
the DUT that was initialized, press [ESCAPE] from the <SET
VALVE FOR xx RPT> screen. This can be useful for setting up
the RPM4-E-DWT to make DUT adjustments or run tests other
than the one defined by the AutoTest.
The display is:
0.0 psi g Hi
Exercise DUT & [ENT]
The top line is the standard RPM4-E-DWT run screen indicating the current
measured pressure (see Section 3.6.1). Exercise the DUT if desired using the
top line indication of the measured pressure and press
[ENT] when complete.
While displayed, the RPM4-E-DWT can be AutoZeroed (see Section 3.7.10).
AutoZeroing before starting the test is recommended.
The display is:
1. Standard RPM4-E-DWT run screen indicating
current measured pressure.
2. Number of this test point/the total number of
test points in the sequence.
3. Pressure to set for this increment in current
pressure unit of measure and measurement
mode.
0.0 psi g Hi
Set 0.0 1/11
Adjust the pressure to the <Set nnnn> value indicated. Set the pressure so that
the DUT, NOT the RPM4-E-DWT, indicates the <Set nnnn> value.
Once the specified pressure has been set, press [ENT] . If the RPM4-E-DWT
pressure reading is in
Not Ready
(pressure not stable) condition (see Section
3.1.2), the RPM4-E-DWT makes an invalid entry sound and displays <Pressure
NOT READY, TRY AGAIN> . Wait for pressure stability or correct the conditions
that are causing the RPM4-E-DWT reading to be excessively unstable and press
[ENT] again. If the RPM4-E-DWT pressure reading is in
Ready
condition, the
RPM4-E-DWT makes a valid entry sound and the display is:
1. Standard RPM4-E-DWT run screen indicating
current measured pressure.
2. Number of this test point/the total number of
test points in the sequence.
3. <F> to indicate freeze (see Section 3.7.7.6)
followed by the RPM4-E-DWT pressure
reading in current units of measure captured
when
[ENT] was pressed in the previous
<Set> screen. This is the reference pressure
that was applied to the DUT when the DUT
indicated the cardinal point. The frozen
pressure value flashes and <OT> follows the
number if the reading was out of tolerance
(definition of out of tolerance is: Set point –
RPM4-E-DWT reading > DUT tolerance)..

Press [ENT] to accept this test point and proceed to the next test point or [

repeat the point.
Repeat the set pressure, take reading and accept data procedure until all points
in the sequence have been accepted.
After the last pressure point in the sequence
has been accepted the display is:
