Page 4: Introduction
1 INTRODUCTION The ZDT Oxygen Analyzer is designed for continuous Remote alarm indication is provided by two relay outputs. monitoring of oxygen content in applications using 'in situ' Relays are programmed to activate when the oxygen level ZFG2 probes. moves either above or below a pre-defined set point. The second alarm relay can also be used as a 'general alarm' Operation and programming of the ZDT Analyzer is via four which activates in the event of an instrument or system fault. -

7 PROGRAMMING… Note. Before commencing a gas calibration procedure the analyzer and probe must be switched on and allowed to operate for at least one hour to allow the system to stabilize thermally. 7.1 Single-point Calibration The calibration sequence involves standardizing the analyzer and the oxygen probe, using air as the test gas. Until a calibration sequence has been completed successfully, the existing slope remains unaffected. -
