  • Page 12: Base Line And System Calibration

    Model 8700 Operator’s Manual v2.9 BASE LINE AND SYSTEM CALIBRATION 5.1 BASE LINE Connect power and nitrogen to the instrument complying with the earlier instructions and turn on the power switch. Note: A base line check should be carried out when first commissioning the instrument, or after a period without use.
  • Page 13 Model 8700 Operator’s Manual v2.9 Click the “BASE LINE” button. The following “‘BASE LINE’ STARTER” screen will appear. Click on a ‘COM’ port button with a green square next to it, where an installed unit is found that is not in use. The ‘baseline screen’ will appear as shown below: For the commissioning of a new instrument it will take a considerable length of time to establish a true low value of the base line.
  • Page 14 Model 8700 Operator’s Manual v2.9 Click the “START” button to begin a baseline. Click the ‘YES’ button to confirm. When the BASE LINE routine is started, nitrogen flows through the instrument to evacuate any residual oxygen. The flow is automatically set to high. The gas will bypass the sensor for a time equal to the PURGE TIME parameter set by the user, the bar located beneath PURGE MFC indicates the percentage of purging completed (see diagram below).
  • Page 15 Model 8700 Operator’s Manual v2.9 When the PURGE TIME is within the last minute of purging the progress bar will turn yellow and the flow rate is adjusted automatically and controlled to 10 cc/min. After the PURGE TIME expires, then the BASE LINE process begins. The O ppm will now be plotted in 1-minute intervals on the graph.
  • Page 16 Model 8700 Operator’s Manual v2.9 A window will appear asking the user to confirm the BASE LINE. Click “YES” and the instrument now has a re-established BASE LINE. At this point, the user may either click the STOP button or allow the BASE LINE to continue in order to verify the result has stabilised.

  • Page 18: System Calibration

    Model 8700 Operator’s Manual v2.9 5.3 SYSTEM CALIBRATION The Model 8700 is calibrated at the factory prior to delivery. It is not necessary to perform a calibration during commissioning of the instrument but a calibration check is recommended every 9 – 12 months. When it becomes necessary to calibrate the instrument a package or a calibration gas can be used.

  • Page 19: Starting The Calibration

    Model 8700 Operator’s Manual v2.9 5.5 STARTING THE CALIBRATION NOTE: For gas calibration only, make sure you position the valve (CALIBRATE/NORMAL) at the rear of the instrument to the CALIBRATE position. Double click the 8700 program icon to start the software. At the main menu, click on the CALIBRATE button.
  • Page 20 Model 8700 Operator’s Manual v2.9 For GAS calibration enter the ppm value of the calibration gas in the O2 (ppm) box; for PACKAGE calibration enter the OTR value of the package in the OTR box. Enter the purge time in the box in the PURGE MONITOR area; a suggested time would be 30 minutes.
  • Page 21 Model 8700 Operator’s Manual v2.9 After the PURGE TIME expires, then the CAL process begins. The OTR will now be plotted in 1- minute intervals on the graph. The OTR value will change on the graph and, after time will become stabilised.

The ‘Purge Settings’, box is where you set the amount of time you wish to purge the sample under test.
  • Page 28 Model 8700 Operator’s Manual v2.9 If the TIMED TEST box is checked, then the user must enter the TEST DURATION desired. When the instrument is used for quality control where repeated tests are performed, the operator will know from previous experience how long a test takes to conclusion. This time may be entered here.
  • Page 29 Model 8700 Operator’s Manual v2.9 It is a laborious task to enter the description of the bottles or packages, to set the cycle time and to determine the purge time. This may need to be done frequently and where the instrument may be used for quality control there is a feature where it is easy to save and recall these settings.

  • Page 30: Notes On Settle To Proceed And Auto Stop

    Model 8700 Operator’s Manual v2.9 7.0.1 Notes on Settle to Proceed and Auto Stop As has been noted before, a single oxygen sensor is used to measure the oxygen transfer rate (OTR) of up to 11 samples. A central valve switches the path for the carrier gas, exposing the sensor to one sample at a time.
