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 PPCH-G with head, AutoZ and range status as well as an indication of whether the
reading was in or out of tolerance and the test point number over the total number of test
points in the QDUT sequence.
OERATION
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.
6000.0 psi g 11/11

Use the forward and backward cursor control keys to scroll through the headers of the other
QDUT AutoTest data files available. PPCH-G 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.
The display is:
1.
PPCH-G pressure logged for the test point.
2. Head, AutoZ and active Q-RPT indicator (same as in the
PPCH-G MAIN RUN screen).
3.
Indication that this point was out of tolerance. Indicates
<IN>
if point was in tolerance. Definition of out of tolerance is
(Nominal point – PPC pressure > DUT tolerance * DUT FS).
4. Number of this test point / total number of points in the
sequence.
6000.5 psi g hzX1H
View data OUT 2/11
Press
[ENT]
to move to the next data point or use the up and down cursor control keys to
scroll backwards and forwards through the test points. The data file header is between the
first point and the last point.
Press
[ESC]
to exit the data file. Confirmation is required to exit the data view function.
3.4.6
<6CONTROL>
PURPOSE
To set the automated pressure control mode for the active range, customize control
parameters for the active control mode, activate default control parameters.
PRINCIPLE
The CONTROL function allows the active control mode for the current range to be set to
dynamic (standard or hi volume), static, monotonic or ramp. The control mode set is specific
to the active range and is saved with that range when ranges are changed. For a complete
description of the operation and purpose of the different control modes see Section 3.2.2.
