    15 minutes and refer to the Material Safety Data Sheet. CAUTION Only use AMI oxygen sensors with AMI Analyzers. Sensors from other manufacturers will degrade analyzer performance, result in accuracy errors and void the warranty.
  • Page 22 SENSOR REPLACEMENT Turn the 3-WAY SELECTOR Valve to the OFF position. Remove the CELL CAP by turning it counterclockwise. Remove the expired sensor. Open the bag containing the new oxygen sensor. (Note: do not remove the stainless steel shorting clip yet) Using the plastic handle, quickly install the sensor into the sensor pocket and carefully push it all the way to the back.

  • Page 23: Calibration

    CALIBRATION Every MODEL 210BX unit undergoes rigorous internal quality tests prior to shipping. This Note: includes a complete electronics and in-depth gas test. For the best accuracy, calibrate your Analyzer monthly using a calibration gas standard. We recommend selecting a percent level of oxygen near your measurement range of interest in a background of nitrogen (example: 5.0% O...

  • Page 26 DISPLAYING THE CURRENT SPAN FACTOR Up Arrow Button Press the UP ARROW BUTTON. IMPORTANT: The SPAN FACTOR is an indication of sensor life. The span factor is accurate only after an accurate callibration has been completed. The SPAN FACTOR of a new oxygen sensor is in the range of 400 to 600. Over time, as the oxygen sensor ages, each calibration should require an adjustment with the UP ARROW BUTTON to correct for any degradation of the electrochemical sensor output (note: the degradation is approximately 1% of the reading per month).
