ABOUT THIS MANUAL
ABOUT THIS MANUAL
This manual provides the user with the information necessary to operate various PG7000 Piston Gauges. It also includes a great deal of additional information provided to help you optimize PG7000 use and take full advantage of its many features and functions.
This manual covers four PG7000 models: PG7102, PG7202, PG7302 and PG7601. The four models have many features and characteristics in common as well as individual differences. When discussing features that are common to all four models, they are referred to collectively as PG7000. When providing information pertaining to a specific model, that model is referred to by its specific model number.
Before using the manual, take a moment to familiarize yourself with the Table of Contents structure. All first time PG7000 users should read Sections 1 and 2. Section 3 provides a comprehensive description of general PG7000 operating principles. Section 4 covers remote communication with an external computer. Section 5 provides maintenance and calibration information. Section 6 is a quick troubleshooting guide. Use the information in Section 6 to troubleshoot unexpected PG7000 behavior based on the symptoms of that behavior.
Certain words and expressions have specific meaning as they pertain to PG7000s. The Glossary (see Section 7) is useful as a quick reference for the definition of specific words and expressions as they are used in this manual.
FOR THOSE OF YOU WHO “DON’T READ MANUALS”, GO DIRECTLY TO SECTION 2.3 TO SET UP YOUR PG7000. THEN GO TO SECTION 2.4. THIS WILL GET YOU RUNNING QUICKLY WITH MINIMAL RISK OF CAUSING DAMAGE TO YOURSELF OR YOUR PG7000. THEN… WHEN YOU HAVE QUESTIONS OR START TO WONDER ABOUT ALL THE GREAT FEATURES YOU MIGHT BE MISSING, GET INTO THE MANUAL!

1. INTRODUCTION
PG7000 Piston Gauges are reference level pressure standards that operate on the piston gauge principle. 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.
A PG7000 piston gauge consists of the PG7000 Platform, one or several piston-cylinder modules and a mass set. A PG7000 system also includes the means to generate and adjust pressures and to interconnect the system components and a device being calibrated or tested. The system may also include COMPASS® software to assist in executing test sequences, acquiring test data and producing test reports.
There are four PG7000 Platforms: Model PG7102, PG7202, PG7302 and PG7601. These have common PG7000 presentation and features. They are distinguished by their normal operating medium (oil or gas) and the capability to define pressures relative to a vacuum reference.
•PG7102 - Gas operated with gas lubricated piston-cylinder modules (PC-7100/7600 modules)
-Maximum pressure is 11 MPa (1 600 psi)
-Does not support definition of pressure against a vacuum reference
•PG7202 - Gas operated, liquid lubricated piston-cylinder modules (PC-7200 modules)
-Oil operated piston-cylinder modules (PC-7300 modules)
-Its maximum pressure is 110 MPa (16 000 psi) when operated with a PC-7200 module
-Its maximum pressure is 200 MPa (30 000 psi) when operated with a PC-7300 module
-Does not support definition of pressure against a vacuum reference
•PG7302 - Oil operated (PC-7300 modules)
-Maximum pressure is 500 MPa (72 500 psi)
•PG7601 - Gas operated, gas lubricated piston-cylinder modules (PC-7100/7600 modules)
-Maximum pressure is 11 MPa (1 600 psi)
-Supports definition of pressure against a vacuum reference
PG7000 platforms, piston-cylinder modules and mass sets are designed to maximize metrological performance and ease of operation. They include many features that enhance the fundamental precision and stability of pressure measurements as well as simplifying use and reducing the operator influence on the measurements. Extensive monitoring and controlling capability and advanced local and remote user interfaces are integrated into PG7000 Platforms.
Operator interaction with PG7000 and its extensive capabilities is accomplished through the display and keypad of the PG Terminal or from a computer via a standard RS232 or IEEE-488 interface.

2. INSTALLATION
A typical PG7000 system includes the PG7000 Platform (see Section 2.1.1.1), a mass set, (see Section 2.1.1.2), one or more piston-cylinder modules (see Section 2.1.1.3) and other accessories (see the accessory Operation and Maintenance Manual or Instruction Sheet).
The mass loading bell is a metrological element that is part of the mass set.
Like all of the masses, it is preferable not to handle it with bare hands.
Protective gloves are provided in the accessory kit of each PG7000 Platform.
The PG7000 Platform is shipped in a reusable, molded shipping and storage case.
Open the PG7000 shipping and storage case (it is the large, 66 cm x 53 cm x 47 cm case).
Remove the PG Terminal and accessories from upper packing insert. Inspect and inventory the accessories (see Section 2.1.2).
Remove the upper packing insert.
Carefully lift the PG7000 Platform from its position in the lower packing insert. Note the orientation so that the same orientation will be used when PG7000 is repacked.
Reinstall the upper packing insert into the shipping and storage case and store in a safe place.

PG7000™ OPERATION AND MAINTENANCE MANUAL
2.1.1.2 |
MASS SET |
|
|
The stability over time of PG7000 pressure measurements is a function of the stability of the masses loaded on the piston. Precautions should be taken in handling the masses to minimize influences that may change their mass. This includes always wearing protective gloves when handling the masses to avoid contaminating them with body oils and perspiration. Protective gloves are provided in the accessory kits of PG7000 Platforms.
The mass set accessories are shipped in a separate corrugated container. Open the corrugated container and inspect and inventory the accessories.
The PG7000 masses are shipped in reusable, molded shipping and storage cases. The PG7000 masses should be removed from their shipping cases and inventoried when actually setting up the PG7000 system.
The piston-cylinder modules are shipped in PVC bullet cases that are packed in corrugated containers with custom foam inserts.
Open the corrugated containers and remove the piston-cylinder modules and accessories.
The bullet cases screw open by turning the lid counterclockwise.
When reinstalling an oil (PC-7300) or liquid lubricated (PC-7200) piston-cylinder module in its bullet case, be sure to empty out any liquid that may have collected in the hole in the bottom of the case. Excess liquid will not compress, making it difficult to fully close the case and could result in damaging it.
Check that all items are present and have NO visible signs of damage. supplied is provided in Section 2.1.2.1 for PG7000, Section 2.1.2.2 Section 2.1.2.3 for piston-cylinder modules.
A parts list of items for mass sets, and
Each PG7000 Platform is delivered complete with accessories as listed by part number in Tables 1 through 4.

1: These mass sets, on certain piston-cylinder sizes, can cause the maximum working pressure of the PG Platform to be exceeded. Do not exceed the following maximum working pressures:
•PG7201: 11 MPa (1 600 psi)
•PG7202: When using PC-7200 piston-cylinder modules: 110 MPa (16 000 psi)
When using PC-7300 piston-cylinder modules: 200 MPa (30 000 psi)
•PG7302: 500 MPa (72 500 psi)
The mass loading bell and piston make up part of the total mass load but are not included with the mass set. Piston-cylinder modules are purchased and delivered separately. The mass loading bell is delivered with the PG7000 Platform.
