Note: A span gas concentration above 1000 <strong>ppm</strong> dictates the selection of the PERCENT option.19. Advance the reverse shade cursor using the ARROW keys to highlight the desired GAS CONCENTRATION.20. Press the ENTER key to select the highlighted menu option.GAS CONCENTRATIONPERCENTPPM21.

Press the ENTER key to advance the underline cursor right or press the MENU key to advance the underline cursor left toreach to the desired digit of the alarm value.23. Press the ARROW keys to enter the alarm value.24. Repeat until the complete SPAN value has been entered.25. Save the adjustment value by pressing the ENTER key or abort by pressing the MENU key.26. Allow approximately 60 seconds for the calibration process while the processor determines whether the signal output orreading has stabilized within 60% of the full scale low range. Both the Zero Calibrate and Span Calibrate functions result inthe following displays:PASSEDCALIBRATIONORFAILEDCALIBRATION27. If the calibration is successful, the analyzer returns to the SAMPLING mode after 30 seconds.28. If the calibration is unsuccessful, return to the SAMPLING mode with span gas flowing through the analyzer, make sure thereading stabilizes and repeat the calibration before concluding the equipment is defective.29. Before disconnecting the span gas line, place the SAMPLE/BYPASS valve in the BYPASS position.22
30. Disconnect the span gas line.31. Connect a purge gas line of either zero or sample gas with a low oxygen concentration.32. Allow the purge gas to flow for 1-2 minutes to purge the air trapped in the span gas line.33. Place the SAMPLE/BYPASS valve in the SAMPLE position.34. Allow the purge gas to flow in order to purge the sensor of the oxygen trapped inside from the calibration gas and bringthe analyzer online to desired the measurement range.35. Caution: Wait until the reading is stable before proceeding with sampling. The wait time will vary depending onthe amount oxygen introduced to the sensor during calibration and/or when the gas lines were switched.36. Once the reading is stable, place the SAMPLE/BYPASS valve in the BYPASS position.37. Disconnect the purge gas line.38. Connect the sample gas line.39. Allow the sample gas to flow for 1-2 minutes to purge the air trapped in the sample gas line.40. Place the SAMPLE/BYPASS valve in the SAMPLE position.41. Wait until the reading is stable and proceed to sampling.Procedure Air Calibration – Without Integral Pump:1. Review the above Span Calibration procedure and the following instructions before proceeding:(a) Range selection and menu operation – note steps #7-9, #29-30 and #32-33 do not apply.(b) Section 6 Maintenance – instructions for removing the sensor explain how to expose the sensor to ambient air.2. Access the interior of the analyzer by removing the four (4) screws securing the front panel of the analyzer.3. Caution: Do not remove the gaskets from the enclosure. Failure to reinstall the gasket will void the NEMA rating.4. Remove the sensor from the sensor housing as described in section 6 Maintenance.5. Hold the sensor and upper sensor housingwith cable between your thumb and firsttwo fingers.6. The thumb should be on the front of thesensor and to the side – do not coversensing area.7. Ensure the PCB at the rear of the sensormakes contact with the pins inside thesensor housing with the connecting cableand rest the back of the sensor housingwith the connecting cable against the firsttwo fingers.8. With the sensor exposed to ambient air inthe manner described above – resume the procedure and perform steps #10-28.9. Reinstall the sensor as described in section 6 Maintenance.10. Remember steps #29-30 and #32-33 do not apply because for air calibration the SAMPLE/BYPASS valve should already bein the SAMPLE position.11. Perform step #31.12. Skip to step #34 and perform the remainder of the procedure.13. Replace the front cover of the analyzer and ensure that the gasket is replaced to maintain CE approval and NEMA 4 rating.14. Tighten the four (4) screws to secure the front cover.Procedure Air Calibration – with Integral Pump:1. Review the above Span Calibration procedure and the following instructions before proceeding:(a) Range selection and menu operation – note steps #6-10, #29-30 and #32-33 do not apply.2. Select a source of good ambient air.3. Ensure the step #5 is performed and the SAMPLE/BYPASS valve is in the SAMPLE position.4. Open the FLOW VALVE completely – to prevent the pump from drawing a vacuum on the sensor.5. Disconnect any tubing connected to the inlet fitting located on the left side of the analyzer.6. Toggle the PUMP ON/OFF switch to the ON position to operate the integral sampling pump and draw the ambient air spangas into the analyzer.7. With the integral pump operating – resume the above procedure and perform steps #10-28.23
