1. Close ball valve ‘A’ (this will stop gas flowing from the generator to the oxygen analyzer).
2. Allow the oxygen analyzer process arrangement to depressurize before introducing the calibration gas.
3. Once depressurized (this will be shown on the pressure gauge), connect your calibration gas to the
sample point located on the enclosure (page 9). Once connected open ball valve ‘B’ and introduce calibra-
tion gas at 7.25 -145 psi (0.5 - 10 bar). Allow the display to stablize before moving on to the next step.
4. Follow the Sensor Calibration Procedure (page 18).
5. Once calibrated, close ball valve ‘B’, remove the calibration gas and re-open ball valve ‘A’ allowing gas to
flow from the generator.
6. Follow generator start up procedure (page 13)

sensor (if fitted) should be calibrated every 3 months or you should
seek a local calibration authority to discuss further. (See pages 16 - 18 for instructions)
