This manual is intended to provide the user with the basic information necessary to operate an
RPM4/HPMS A70M/A20M reference pressure monitor with high pressure mounting system. It also
includes a great deal of additional information provided to allow you to optimize the use of the instrument
and take full advantage of its many features and functions.
Before using the manual, take a moment to familiarize yourself with the Table of Contents structure:
Sections 1, 2 and 3 should be read by all first time RPM4 users. Section 3 is most important for those
using the local front panel interface but should be read over by all users to familiarize themselves with
general RPM4 operating principles. Section 4 is for remote operation from an external computer. Section
5 provides maintenance and calibration information. Section 6 is a quick troubleshooting guide. Use it to
troubleshoot unexpected RPM4 behavior based on the symptom of that behavior. Certain words and
expressions have specific meaning as they pertain to RPM4. The Glossary, Section 9, is useful as a
quick reference for exact definition of specific words and expressions as they are used in the manual.
For those of you who “don’t read manuals”, go directly to Section 2.3 to set up your RPM4/HPMS and
then go to Section 2.4 for power-up and verification. This will get you up and running quickly with a minimal risk
of causing damage to yourself or your new instrument. THEN… when you have questions or start to wonder
about all the great features you might be missing, get into the manual!
RPM4/HPMS A70M/A20M-AF is usually delivered as part of an PGC-10000-AF system which includes a
PGC1-10000-AF pneumatic pressure controller and a GB-152-AF gas booster. The PGC1 and the GB-152 have
their own Operation and Maintenance Manuals.
Manual Conventions
(CAUTION) is used in throughout the manual to identify user warnings and cautions.
(NOTE) is used throughout the manual to identify operating and applications advice and additional
explanations.
[ ] indicates direct function keys (e.g., [RANGE]).
< > indicates RPM4 screen displays (e.g., <1yes>).
