E-DWT-H OPERATION AND MAINTENANCE MANUAL

 PRINCIPLE
RPM4-E-DWT supports AutoTest automated tests (see Section 3.1.3). When an
AutoTest is run, the RPM4-E-DWT pressure measurement accepted by the
operator at each point is logged. The logged pressure measurements 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
<1data> . In
addition, the last ten data files recorded can be viewed anytime by selecting
[SETUP] , <5ATest> , <1data> .
Data File Protocol
Up to ten data files are buffered, ten at a time, in RPM4-E-DWT memory. When
a new AutoTest run is completed, its data file goes to the back 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 AutoTest. The second line is the date
(YYYYMMDD) and time (HH:MMa) at which the last point of the sequence
was accepted.
Following the data file header, each test point is recorded including the pressure
reading of the RPM4-E-DWT 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 Sequence.
 OPERATION
To access the AutoTest results data file viewing function press [SETUP] ,
<5ATest> , <1data> .
The first display is the data file header which can be used to toggle through
data files:
1. Full scale of the AutoTest with pressure unit of
measure and measurement mode.
2. Number of test points executed/total number
of points in the AutoTest.
3. Date and time that the last point in the
AutoTest was executed.

Press [+/-] or [
→
] to scroll through the headers of the other AutoTest data files
available. RPM4-E-DWT stores up to ten AutoTest 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 AutoTest data file you would like to view appears,
press
[ENT] to view the first point of the identified AutoTest data file.
The display is:
1. RPM4-E-DWT reading logged for the test
point.
2. Head, AutoZ and Q-RPT indicator (same as in
the RPM4-E-DWT main run screen) (see
Section 3.6.1).
3. Indication that this is an AutoTest data file
view screen.
4. <FA> indicating that the AutoTest was a File
AutoTest or <QA> indicating a Quick
AutoTest. This is preceded by <OT> if the
test point was out of tolerance (definition of
out of tolerance is Set point – RPM4-E-DWT
reading > DUT tolerance).
5. Number of this test point over total number of
points in the AutoTest.
