3. OPERATION

After the last point of the test sequence has been executed, PPCH vents and
operation returns to the main run screen.
Regardless of whether the sequence was set up for next increment on time
delay or on ENTER, pressing [ENT] always causes the sequence to proceed to the
next increment. This feature can be used to skip one or several increments if desired.
To interrupt the sequence at any time,
press
[ESC]
. Pressure control ceases
immediately and the display goes to:
Abort Quick AutoTest
1no 2yes
Select
<2yes>
to cause the sequence to abort and return to the MAIN RUN
screen. Select
<1no>
to cause the sequence to resume where it left off.
All Quick Sequences end with a VENT command after the last point. To avoid
the VENT, press [ESC] rather than [ENT] after the last point.
3.3.6.2
QDUT AUTOTEST
OPERATION
The QDUT AutoTest AutoRanges the PPCH (see Section 3.3.4) based on the
span and tolerance of a DUT before running a test sequence. QDUT AutoTest
also calculates DUT in or out of tolerance conditions and collects data while
running the test. See Section 3.4.5 for information on QDUT AutoTest data files.
To run a QDUT Test, press
[AutoTest]
and select
<2QDUT>
.
The display is:
Run current QDUT
AutoTest: 1yes 2no
This selection provides the choice between running the last QDUT Test,
including AutoRanging the PPCH based on the previously entered DUT
characteristics or setting up a new QDUT Test definition. Select
<1yes>
to rerun
the last QDUT Test (see below in this Section). Select
<2no>
to define a new
QDUT Test.
When
<2no>
is selected from the Run Current QDUT Test menu, the set-up/edit
routine is accessed. The information needed to AutoRange PPCH based on the
DUT characteristics is then collected (see Section 3.3.4).
The first display is the selection of the
pressure control mode in which the test is
to be run (see Section 3.4.6).
Control: 1dynamic
2static 3monotonic
Select the pressure control mode that is to be used by the PPCH when running
the test points.
The next display is the selection of the
measurement mode of the DUT (see
Section 3.3.3). If only gauge mode is
available, this display is skipped.
DUT measurement mode
1abs 2gage
Select the measurement mode of the DUT that is being tested. If the desired
measurement mode is not available, the QRPTs available to PPCH do not support the
measurement mode or it is turned off.
