1.
Indication that this is a screen of the proposed
AutoRange range.
2. Designator and position of the Q-RPT that
AutoRange has selected to cover the QDUT
full scale and measurement mode.
3.
Pressure unit of measure specified in QDUT
setup.
4.
AutoRange full scale pressure in gauge mode
and absolute mode if available.
AutoRange A140M X1H
psi 12000g/12000a
The cursor keys or the
[RPT]
key can be used to toggle through other Q-RPTs
available to cover the QDUT specified range and measurement mode. When the
desired Q-RPT is displayed, press
[ENT]
to accept the proposed AutoRange.
The QDUT AutoTest can now be run. The display is:
1. Indication of minimum and maximum
pressure included in the sequence which is
about to run.
ENTER to run psi g
0.0 to 10000.0
This screen is offered for the user to check, prior to execution, that the correct
sequence is defined and that it does not exceed the range of the device or
system being tested.
Pressing
[ESC]
twice returns to the MAIN RUN screen without sequence
execution (this feature can be used to AutoRange the PPCH-G based on DUT
characteristics without running a specific test sequence). Pressing
[ENT]
causes
sequence execution to proceed.
The display is:
0.000 psi g IH
Prep & ENTER 0/11
Perform any operations that are needed before running the test such as making
connections or exercising the DUT. The PPCH-G direct pressure control keys are
active to allow pressure adjustment (see Section 3.1.3). When ready to begin the
test, press
[ENT]
.
Dynamic pressure control begins to set the first target value of the sequence
(or vent executes if the first increment is zero). The display is:
1. Indication of sequence increment that is
currently being executed / total increments in
sequence. Changes to ENTER once
Ready
condition has been achieved at target value.
48.335 psi g IH
T60.000 D 2/11
Except for the bottom right hand corner, the sequence run display is identical to
the normal MAIN RUN screen (see Section 3.1.1). The bottom right corner
provides information on sequence execution. This information updates as each
sequence increment is executed.
Once a
Ready
condition has been achieved (see Section 3.2.3), use the direct
manual pressure control keys (
[
]
and
[
]
) to adjust the pressure set by
PPCH-G until the DUT reads the cardinal value of the pressure increment.
Once the DUT indicates the cardinal value of the pressure increment, press
[ENT]
. The display is:
