    1 INTRODUCTION 2 PREPARATION 2.1 Checking the Code Number The Models 4681 and 4686 Oxygen Transmitters are designed for continuous monitoring of Oxygen content in 2.1.1 Wall-/Pipe-mounted Instruments – Fig. 2.1 applications using 'in situ' ZGP2 probes. Operation and programming of each Transmitter is via four tactile membrane switches and a digital display located on the front of the instrument.

    …7 PROGRAMMING Note. Before commencing a gas calibration procedure the analyzer and probe must be switched on and allowed to run 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.
