PPC2+ BG0002 Operation and Maintenance Manual
ABOUT THIS MANUAL
This manual is designed to be used in conjunction with the PPC2+ Operation and Maintenance Manual (Document Number 550091). It contains information specific to the BG0002 model of PPC2+ Pressure Controller/Calibrator.
PPC2+ BG0002 is identical in conception and most features to other PPC2+ models. PPC2+ BG0002 is a specialized PPC2+ model designed to optimize very low gauge pressure performance. This manual covers the aspects of PPC2+ BG0002 that differ from other PPC2+ models.
To operate a PPC2+ BG0002, use the PPC2+ Operation and Maintenance Manual (Document Number 550091) and follow the instructions and information. Refer to this manual for details on BG0002 specifications, installation and set up, pneumatic schematic differences, and [SPECIAL], <5Valves> operation. PPC2+ BG0002 is normally used in conjunction with accessory package PK-PPC-BG-DVU (P/N 401699). This package is delivered with its own instruction sheet.
Manual Conventions

PPC2+ BG0002 Operation and Maintenance Manual
1. INTRODUCTION
1.1 PRODUCT OVERVIEW
PPC2+ BG0002 is a special model of the PPC2+ line of pressure controller/calibrators. PPC2+ BG0002 is identical to other PPC2+ models except for:
1)Use of a special low pressure “bi-directional gauge” reference pressure transducer (RPT).
2)This model has only one RPT. It does not support dual RPTs.
3)Inclusion and control of two additional internal control valves (a TEST(+)/TEST(-) bypass and a TEST(-) vent) with local and remote control capabilities for both.
4)Special recalibration recommendations for the very low pressure, bi-directional gauge RPT.
PPC2+ BG0002 is normally used in combination with accessory package PK-PPC-BG-DVU (P/N 401699) which includes two thermally isolated volumes installed in the test line to improve control stability. This package is delivered with its own instruction sheet.
Once a PPC2+ BG0002 has been put into service, its operation is identical to other PPC2+ models.
This manual is intended to be used as a supplement to the PPC2+ Operation and Maintenance Manual (Document Number 550091). To operate a PPC2+ BG0002, use the PPC2+ Operation and Maintenance Manual and refer to this manual for aspects specific to the BG0002 model. These are primarily the operating specifications, installation and use recommendations, recalibration recommendations.
