3.1 OVERVIEW

COMPASS for PPC/RPM is an application program intended to automate the test and calibration process to the extent supported by your calibration hardware and appropriate for the DUT being calibrated. COMPASS supports autom ated operation of DHI PPC and RPM transfer standards but can als o be used with any type of pres sure standard from any manuf acturer. This feature allows COMPASS to be used systematically to provide consistent data formats and report generation for all of your pressure calibrations.
COMPASS sets up and maintains files on devices under test (DUT) (see Section 6) and testing procedures (see Sec tion 7) to assoc iate with DUTs . These files are recalled to run tests. Tests are run using the hardware th at has been configur ed (see Section 8.2) in COM PASS. While running a tes t, data is acquired and stored in a standard ASCII comma or tab delimited data file (see Section 12). Within COMPASS, data files m ay be viewed (see Section 9 .2), used to generate plots (see Sec tion 9.4) and used to generate reports (see Section 1) which can be customized with user edited templates. COMPASS operations foll ow conventional Windows protocol for file management, menu and message formatting, graphics and editing.
Devices under test (DUT) and test pr ocedures are def ined and recorded in *.dut and *.ts t files. To run a test, first a *.dut f ile m ust b e create d (see Secti on 6.2) to def ine the DUT that wil l be test ed and a *.ts t file must be created (se e Section 7.2) to pro vide COMPASS with the exac t testing procedure f or that DUT. The hardware configurat ion, including the pressure referenc e device, the electrical measuring dev ice (if present) and the computer ’s IEEE 488 card (if present) used to run the t est is specified with a Hardware Configuration Tool ( see Section 8.2). Once “DUT” and “test” files have been set up, and the hardware configuration has been defined, tests can be run (see Section 5.2).
Many operationa l preferences relating to how test are i nitialized and ru n, and how data is g athered and stored are configurabl e with user options (see Sectio n 8.3). The use of these configura ble preferences results in a test environment that is customizable to meet the testing needs of a diverse group of end users.
As a test runs, the data is c oll ected in a “ l og” f ile ( s ee Sect ion 12 .2) . When the test completes, the r es u lts of the test are copied f rom the “ log” f ile in to “da ta” f iles . “Data” f iles are des igned to be eas il y exported t o other applications by the u ser for further analysis or report ge neration. In addition, COMPASS includes integrated analysis and reporting func tions which allo w full custom ization of repo rts (see Sec tion 1). Any number of custom report formats can be creat ed and employed. Re ports can then be edit ed, printed or saved. A plottin g function allows vario us auto-sc aled err or plots fo r test results t o be view ed and printed (see Section 9.4).
Detailed inform ation and assis tance on COMPASS application a nd functions ar e available i n this manual and with on-line help (accessed by pressing [F1] or selecting [H

3.1.1 BASICS SUMMARY

In summary, the following steps and sections s hould be refer red to while trying to s et up and run a test for the first tim e. Subseque nt tests will onl y require a sel ection of the desired DUT and test file. The Run T est section of this manual has a m ore detailed explanation of the requirements to run a test in COMPASS (see Section 5.2). Several COMPASS exam ples and frequently asked ques tions are in t he Qu ick Tips section of this m anual ( see Section 1 3). These sections are also very useful in gett in g star te d.
Select [DUT], [Create] to create a DUT (see Section 6.2). A DUT that outputs an electrical signal suc h as V, m V or m A will most lik ely use a dig ital m ultimeter . This DMM should be set up in the program configuration (see Section 8.2).
Select [Tools], [Configure Hardware] to update the program configuration (see Section 8.2). This includes setting up the press ure reference as well as any other peripheral devices required by a DUT. This option should be used t o set up a DMM, multiplexer and s elect the system IEEE 488 i nterface card. Once these selec tions are made there is no need to access the configuration unless a change in one of these devices occurs. M ake sure the des ired selec tions are m ade on the [CONFIGURATION] tab of the hardware configuration.
Select [Test] , [Create Test] to create a test that will define the pr essure sequence and other aspects of the testing procedure (see Section 7.2).

Identifies the DUT that is currently being displayed in the test point log and in the run time plot. DUTs are identified by serial number/ID. If multiple DUTs are being tested, a drop­down menu to select an individual DUT or <All> is available.
Selecting <Pre Test> causes information on the leak test and/or cycling (exercising) conducted at the beginning of the test to be displayed i f these were included in the test definition.
The data for each test point is recorded and displayed in the test point log. If the DUT error for the current test point exceeds the DUT tolerance, the computer beeps (if audible feedback is enabled) and the row containing the t est point is highlighted (only the most recent out of tolerance test point is highlighted). The status column for this point will include a <T> for out of tolerance.
When testing multiple DUTs, selecting a single DUT in the <Current Display> selector causes the complete test log for the DUT to be shown; selecting <All> causes the current point for all the DUTs to be shown. The change f rom a single t o all DUTs c an be made at any time.
<Test Point> is the number of the pressure point in the pressure point sequence. <Reference Pressure> is the reading from the reference pressure device. <DUT output> is the output recorded from the DUT. <DUT Pressure> is the pressure
calculated from the output using the output and pressure spans from the “DUT” file. If the DUT output is pressure, DUT output and DUT pressure are identical.
<Error> is the difference between the DUT pressure and the ref erence pressure (DUT pressure – reference pressure).
The <Status> column reports the status of the test point.
<OK> indicates that the test point executed normally and the DUT error was in tolerance. <T> indicates that the DUT error was out of tolerance. <S> indicates that data was taken from the reference when the reference was not ready

5.2.1.5 REFERENCE VERIFICATION
The reference verif ication sc reen is pr esented identif ying the sour ce of r eference pressures to be used in ru nning the test. If COMPASS can communicate with the reference remotely and the reference has multiple ranges, the reference range selection tool and h ead adjustment is also included . If this step is turned OFF, the screen is not shown, the recommended range is automatically accepted and the current head (if the reference supports head corrections) is accepted. See the Reference Pressure Device Operations and Maintenance Manual for details on head corrections.
The reference shown is the reference currently selected in [T
ools], [Config
Hardware], [CONFIGURATION]. To change references, abort the test and go to
ools], [Config Hardware], [CONFIGURATION] to set up and/or select a
[T
different reference (see Section 8.2.1). If COMPASS is able to communicate remotely with the reference, the range
selection tool is disp la yed. T his too l rec omm ends the range tha t COM P ASS has determined to be the optimum range based on the span and pressure measurement mode of the DUT . A different range may be selec ted by clicking on the corresponding button.
If COMPASS is able to communicate remotely with the reference and the reference supports automated pressure head corrections the current head correction height is displayed and m ay be edited to reflect the correc t height for the current setup. The head correction un its and/or medium cannot be change d using this pop-up. To change these, abort the test and m ake the changes using the reference device’s front panel function keys then restart the test. See Reference’s Operatio n and Mainte nance Manua l for com plete information o n the head correction function).
Erroneous data may be logged if the reference device’s characteristics are
modified manually without restarting the test. Always restart the test if pressure reference device changes are made using the reference device’s front panel.

5.2.1.6 SETUP DUT(S)
The setup DUT( s) screen is pr esented. T his screen is intended to a llow input of DUT identification and communication details if necessary.
See Section 6.2 for information on DUT profiles vs. definition files and DUT
data acquisition type.
Do not use the following characters in the serial number or identification
fields: \,/, :, *, ?, “, <,>, |, a comma or tab character. These characters will cause problems when importing the “data” file or creating the “data” file directory.
The setup DUT(s) screen’s appearance and operation vary depending on whether the DUT file being run is a DUT definition or a DUT profile and on th e DUT’s data acquisition type (see Section 6.2):
If the DUT file is a DUT definition file and the DUT data acquisition type is
manual, the screen sets up for a single DUT. The screen serves only for DUT
verification as the DUT ide ntification comes from the *.dut file and there are no communications to verify. If the setup DUT step is turned OFF, setup DUT is omitted entirely.
If the DUT file is a DUT definition file and the DUT data acquisition type
is DMM, RS232 or IEEE 488, the screen sets up for a single DUT.
DUT communication details c an be verif ie d, c han ged a nd tested. If the setup DUT step is turned OFF, s etup DUT is omitted ent irely. This f eature can be removed only when a DUT definition is used with DMM data acquisition or the default interface parameters (see Section 8.3.3) will work with the current DUT.
If the DUT fi le is a DUT p rofil e file , the scr een se ts f or entr y of up to 5 0 DUTs . The screen requires entry of a DUT serial number for each DUT to be t es ted. Serial number entr y in the DUT position is the means b y which COMPASS determines how many DUTs to include in the test run and the position of the DUTs. Identification is not a requ ired field. If the DUT data acquisiti on type is DMM, RS232 or IEEE 48 8, DUT comm unication det ails for each DUT individually can be verified, changed and tested. If the setup DUT step is turned OFF, the setup DUT sc reen will still ap pear and r equire serial num ber entry to identify the DUTs to be tested.
To check communications with the DUT(s), click the <Communications Test> button. COMPASS attempts to comm unicate with all DUTs that have had a serial number entered using the command specified in the DUT file and the current comm unications settings. If communication is successful, the DUT output is update d in the <D UT O utp ut> column. If communication fails, an error message is displayed.
