    …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 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.
