PPC2+?” An HP34970A is a DMM/Multiplexer unit manufactured by Hewlett Packard that can contain up to 60 relay channels which can be individually routed to an internal multimeter. Fluke and Keithley also manufacture similar instruments. To read a voltage on channel 1 of this instrument requires the command “MEAS:VOLT:DC? (@101)”.

® COMPASS FOR PPC/RPM™ USER’S MANUAL the DC voltage measurement. Issuing the command “READ?” following a measure command will output another reading using the same channel and reading configuration. It is a short cut to issuing another measurement command. This example demonstrates how to set up a DMM and multiplexer configuration.

The <Data Acquisition> column displays “DMM+Multiplexer” to denote the fact that the multiplexer is part of the configuration of the DMM data acquisition DUT. Press <OK> to start the test. COMPASS will step through the test point sequence gathering data from the PPC2+ and all 8 DUTs (see Section 5.2.2).
Page 103: How Do I
14. QUICK TIPS 14.1 HOW DO I? Set up and run a test? Create a *.tst file to define the test procedure (see Section 7.2). Create a *.dut file to define a device under test (see Section 6.2). Configure the test hardware to be used to run the test (see Section 8.2.1). Run test (see Section 5.2).
Page 104 ® COMPASS FOR PPC/RPM™ USER’S MANUAL Repeat the same test several times without having to pause or restart the test? Specify multiple test cycles in the *.tst file that defines the test procedure. In the [Sequence] tab of test definition (see Section 7.2.6) specify a number greater than one under <Number of Test Cycles>. The test pressure sequence will run for the number of times specified without initializing between runs.
Page 105 14. QUICK TIPS Set up and use a combination DMM/multiplexer in a single unit such as the HP34970A? There are two possibilities: 1. Treat the single device as if it were a separate DMM and multiplexer. You actually set it up “twice”, once in the <DMM>...

15. CALCULATIONS 15.1 OVERVIEW COMPASS operation includes certain internal calculations. Most of these calculations are related to analyzing the data taken during a test run. The internal calculations performed by COMPASS are documented in the sections that follow. The calculations have been verified both by comparison of the program code content to the defined formulas and by parallel manual calculation.
Page 108: Tolerance
® COMPASS FOR PPC/RPM™ USER’S MANUAL − ×100 % Re ading 15.4 TOLERANCE The determination of whether a point is in or out of tolerance depends on the type of tolerance selected, and the DUT and reference pressures. Tolerance values may be in %DUTspan, %Reading or a combination of the two (see Section 6.2).
Page 109: Hysteresis
15. CALCULATIONS If the test point sequence is made up of corresponding ascending and descending (or vice-versa) points, linearity is calculated by taking the average between corresponding DUT pressures, drawing a straight line between the minimum and maximum DUT pressures and determining the maximum deviation of any average DUT pressure from this line.

16. DDE SUPPORT 16.1 OVERVIEW COMPASS for PPC/RPM can be monitored using Windows Dynamic Data Exchange (DDE). This feature gives users the ability to write programs that monitor COMPASS tests and take specific actions during the test process. The monitoring program should not attempt to change the behavior of COMPASS using the DDE interface.

17. TROUBLESHOOTING 17.1 OVERVIEW COMPASS for PPC/RPM is a sophisticated software package with many advanced features that can be misused and/or misunderstood. Before assuming that unexpected behavior is caused by a software or hardware defect, the operator should use this manual in conjunction with the documentation of other instruments used with COMPASS to determine the appropriate behavior.

18. APPENDIX 18.1 GLOSSARY Averaging Time The time over which reference and DUT readings are made when taking data at a pressure point. COMPASS makes as many readings as possible during the averaging time and then averages the readings to arrive at the reference and DUT reading for the pressure point. Control Time Out The amount of time, when setting a pressure point in a test using automated pressure control, that COMPASS will wait for a ready condition.
Page 116 ® COMPASS FOR PPC/RPM™ USER’S MANUAL Measurement Mode Whether pressure is being measured relative to absolute zero or vacuum (absolute mode) or relative to atmospheric pressure (gauge mode). Measurement mode of the DUT refers to whether the DUT is configured to measure absolute pressure or gauge pressure.
