This manual provides the user with the basic information necessary to operate an RPM3/HPMS
A30000/A6000-AF Reference Pressure Monitor with High Pressure Mounting System. It also
includes a great deal of additional information provided to help you optimize use of the instrument
and take full advantage of its many features and functions.
Before using this manual, take a moment to familiarize yourself with the Table of Contents structure.
All first time users should read Chapter 2. Chapter 3 provides a comprehensive description of
general RPM3/HPMS operating principles. Section 3.1.7 describes the automated Sequence
function used to run calibrations and verifications of typical instruments under test. This is the way
the instrument is typically used. Chapter 4 is for remote operation from an external computer.
Chapter 5 provides maintenance and calibration information. Chapter 6 is a quick troubleshooting
guide. Use it to troubleshoot unexpected RPM3/HPMS behavior based on the symptoms of that
behavior. Certain words and expressions have specific meaning as they pertain to this product. The
Glossary is useful as a quick reference for exact definition of specific words and expressions as they
are used in this manual.
RPM3/HPMS A30000/A6000-AF is usually delivered as part of an HGC-30000-AF system which
includes an OPG1 hydraulic pressure generator/controller. The OPG1 has its own Operation and
Maintenance Manual.
FOR THOSE OF YOU WHO “DON’T READ MANUALS”, GO DIRECTLY TO SECTION 2.3 TO SET UP YOUR
RPM3/HPMS AND THEN 2.4 FOR POWER UP AND VERIFICATION. THIS WILL GET YOU RUNNING
QUICKLY WITH MINIMAL RISK OF CAUSING DAMAGE TO YOURSELF OR YOUR NEW RPM3. THEN…
WHEN YOU HAVE QUESTIONS OR START TO WONDER ABOUT ALL THE GREAT FEATURES YOU
MIGHT BE MISSING, GET INTO THE MANUAL!

1. INTRODUCTION
1.1 PRODUCT OVERVIEW
RPM3/HPMS A30000/A6000-AF is the combination of an RPM3 A5000/A6000-AF reference
pressure monitor and an HPMS High Pressure Mounting System. The combination of an
RPM3/HPMS A30000/A6000-AF and an OPG1-AF oil pressure generator make up the
HGC-30000-AF hydraulic gauge calibrator. The OPG1-AF has its own Operation and Maintenance
manual.
RPM3 A30000/A6000-AF is a stand-alone, microprocessor driven, reference pressure monitor
intended to accurately measure oil pressure in a variety of pressure calibration, measurement and
testing applications. It has been designed to provide very high performance and extensive features
combined with maximum versatility and ease of use. RPM3 A30000/A6000-AF is a special version of
the standard DHI RPM3 product configured specifically for the USAF HGC-30000-AF hydraulic
gauge calibrator.
The HPMS mounts the RPM3 at a convenient viewing angle and contains the hardware to isolate the
RPM3’s low pressure transducer (A6000) when the high pressure transducer (A30000) is in use.
RPM3 A30000/A6000-AF uses two high accuracy reference pressure transducers (RPTs) and an on-
board barometer to measure pressure.
RPM3 A30000/A6000-AF is controlled locally by the operator using its front panel display, keypad
and foot pedal or remotely by a computer using ASCII character command strings over its RS-232
and IEEE-488 interfaces.
RPM3 A30000/A6000-AF has six pressure measurement ranges from 0 to 2 000 psi (7 MPa) to 0 to
30 000 psi (200 MPa) in gauge and absolute measurement modes.
RPM3/HPMS A30000/A6000-AF is usually delivered as part of an HGC-30000-AF system which
includes an OPG1 hydraulic pressure generator/controller. The OPG1 has its own Operation and
Maintenance Manual.

1.2.2 PRESSURE MEASUREMENT SPECIFICATIONS
RPM3 A30000/A6000-AF is configured with two reference pressure transducers (RPT).
Each transducer has three ranges. The RPTs are of the absolute pressure type with an
evacuated, permanently sealed reference. Absolute RPTs measure both absolute and
gauge pressure. Gauge pressures are defined by offsetting atmospheric pressure
dynamically with compensation for atmospheric changes using an on board barometer.

reference pressure transducer. When using an absolute RPT for gauge mode
measurement add ±2.5 Pa (0.00035 psi) to the precision specification to take into
account the resolution and short term stability of the on-board barometer used for
dynamic atmospheric pressure compensation.
2Stability: Maximum change in zero and span over 180 days for typical transducer used
under typical conditions. As stability can only be predicted and varies from transducer to
transducer, stability for a specific RPT should be established from experience.
3Measurement Uncertainty: Combined precision, stability, temperature effect.

The on-board barometer is NOT used as a source of absolute accuracy. It is used
only to measure changes in atmospheric pressure for dynamic compensation of the
atmospheric pressure offset when using an absolute reference pressure transducer
to make gauge pressure measurements (see Section 3.4.1, Gauge Mode with an
Absolute RPT, Dynamic Compensation for Atmospheric Pressure).

2.2 SITE REQUIREMENTS
The RPM3/HPMS A30000/A6000-AF is typically delivered as part of an HGC-30000-AF hydraulic
gauge calibrator that includes an OPG1-30000-AF that has its own Operation and
Maintenance Manual. See the OPG1-30000-AF Operation and Maintenance Manual for information
on site requirements for the HGC-30000-AF.
Install RPM3/HPMS A30000/A6000-AF on any stable surface at a convenient height. Consider the
placement of the FOOT SWITCH which may need to be accessed frequently while
running calibrations.
Support facilities required for RPM3/HPMS A30000/A6000-AF include an electrical power source of
85 to 264 VAC, 47 to 440 Hz.
2.3 INITIAL SETUP
2.3.1 PREPARING FOR OPERATION
To prepare RPM3/HPMS A30000/A6000-AF for check out and operation:
•Remove the plastic plug from the RPM3/HPMS A30000/A6000-AF rear panel
TEST connection.
•Remove the protective plastic sheet from the RPM3 front panel display.
