PPC3™ OPERATION AND MAINTENANCE MANUAL

RPM4 has its own, independent overpressure function. When a Q-RPT on an
RPM4 is active, both the PPC3 and the RPM4 may execute overpressure
routines in response to an overpressure condition of the RPM4. See the
RPM4 Operation and Maintenance Manual for information on the RPM4
overpressure function.
3.4.5 <5ATEST>
PURPOSE
To view the data files that are created when QDUT AutoTests are run (see Section 3.2.6.2).
PRINCIPLE
PPC3 supports QDUTAutoTests (see Section 3.2.6.2). When a QDUT AutoTest is run, the
PPC3 pressure accepted by the operator at each point is logged. The logged pressure and
an identifying header are stored in a data file. The data file can be viewed immediately
following the last point of the sequence by selecting <3data>. In addition, the last data files
recorded can be viewed anytime using [SETUP], <5ATest>.
Data File Protocol
Up to ten QDUT AutoTest data files are buffered, ten at a time, in PPC3 memory. When a new
test is completed, its data file goes to the front of the queue and the oldest data file is deleted.
Data files are identified by a header whose first line is the full scale of the DUT and the
number of test points in the QDUT AutoTest sequence. The second line is the date
(YYYYMMDD) and time (HH:MM:SS) at which the last point of the sequence was accepted.
Following the data file header, each test point is recorded including the pressure setting of
the PPC3 with head, AutoZ and range status as well as an indication of whether the reading
was out of tolerance and the test point number over the total number of test points in the
QDUT sequence.
OPERATION
To access the QDUT AutoTest data file viewing function press [SETUP], <5ATest>.
The first display is the data file header which can be used to toggle through data files:
1. Full scale of the QDUT AutoTest sequence with pressure unit
of measure and measurement mode.
2. Number of test points completed / total number of test points
in the sequence definition.
3. Date (YYYYMMDD) and time the last point was completed.

Use the forward and backward cursor control keys or to scroll through the headers of the
other QDUT AutoTest data files available. PPC3 stores up to ten data files in order of
execution with a new data file pushing all the files back and deleting the oldest one. When
the header of the data file you would like to view appears, press [ENT] or the down cursor
control key to view the first point of the identified sequence.
