    ABOUT THIS MANUAL This manual provides the user with the information necessary to operate and maintain a PG7601-SYS-AF gas operated piston gauge system. Before using the manual, take a moment to familiarize yourself with the Table of Contents structure. All first time PG7601-AF users should read Section 2 and 4. Section 5 covers remote communication with an external computer.

  • Page 15: 1. Introduction

    Pressure is defined by balancing it against the force exerted by a known mass accelerated by gravity on the effective area of a piston-cylinder. PG7601-SYS-AF covers the pressure range of 7 to 7000 kPa (1 to 1 000 psi) in absolute and gauge modes with semi-automated operation and state of the art measurement uncertainty.

    PG7601-SYS-AF™ OPERATION AND MAINTENANCE MANUAL PISTON GAUGE PLATFORM AND TERMINAL (PG7601-AF) The heart of the PG7601-SYS-AF is the PG7601-AF gas operated piston gauge and its piston-cylinder modules and mass set. The PG7601-AF operates on the principle of the piston gauge in which pressure is defined by balancing it against a known force on a known area (see Figure 4).

In normal operation, the PPC3-7M-AF pressure controller operates automatically under the control of the PG7601-AF platform and the PPC3-7M-AF front panel is not used. The exception is when the pressure controller is used manually and controlled by the operator through its front panel direct pressure control keys (see Section 4.2.2.2).

    40 to 60 hours of operation. If symptoms of contamination develop rapidly with operation after cleaning, there is almost certainly a source of contamination within the PG7601-SYS-AF system. This source must be eliminated to reduce piston-cylinder cleaning frequency. Usually, the source is the return of unclean gas from DUTs that have contaminated the system or the test gas supply (which contains humidity or lubricating oil).
