  • Page 15: Introduction

    INTRODUCTION INTRODUCTION 1.1 BASIC CONCEPTS The Gas Delivery Unit (GDUnet) can be used in three different applications: • As a gas delivery unit in an Instrument Management System (IMS) - see paragraph (a). • As a gas delivery unit in a workshop system - see paragraph (b).
  • Page 16 (b) The GDUnet as a gas delivery unit in a workshop system. A workshop system is used by an instrument technician to service, repair and calibrate / test instruments annually, or more frequently if required.
  • Page 17: Calibration Gases

    The GDUnet is connected to cylinders of calibration gas to ensure that a consistent standard can be maintained against which the instrument can be checked. The GDUnet can connect up to 8 gas cylinders (a 4 gas cylinder version is also available). 1.2.1 Recommended Types The instrument should be calibrated in the gas it will be used in, rather than using calibration factors, i.e.
