It is best to calibrate the MAXO2 analyzer to a known documented oxygen concentration at a pressure and flow similar to your clinical application. Calibrating the MAXO2 analyzer at lower concentrations with a known oxygen value is also acceptable and may provide additional accuracy if the calibration gas is closer to the environment in which the MAXO2 analyzer will be used. A “known” value of oxygen is defined as an oxygen source which has a traceable certificate and / or USP certification.

Note: Before beginning calibration the MAX-250 sensor must be in thermal equilibrium. You may also need to be aware of other factors which affect device calibration values. For more information, refer to “Factors Influencing Calibration”, section 2.2.4 in this manual.

2.2.2 To Calibrate the MAXO2 Analyzer

1)Connect the sample hose to the barbed fitting on the bottom of the unit.

2)Attach the other end of the sample hose to the source of the known oxygen concentration and initiate flow of the calibration gas to the unit (2 liters per minute is recommended).

3)Using the ON/OFF key, make sure the unit is in the power on mode.

4)Allow the oxygen reading to stabilize. This will normally take about 30 seconds or more.

5)Press the LOCK/UNLOCK key to unlock the keypad. “UL” will appear on the display for about 1 second and then the "%" sign will disappear from the display.

6)Press the CALIBRATE key on the keypad. The word "CAL" will appear on the display for about 1 second and then the "%" sign will start to flash.

7)Use the and arrow keys to adjust the displayed oxygen concentration to the level of the known concentration. Pressing the arrow keys changes the value in .1% increments. If the keys are held down for more than 1 second the display will scroll at a rate of .4% per second.

Note: If 10 seconds elapse between key actuations, the system will store the latest calibration value and will revert to normal operation. If this occurs inadvertently, simply repeat the calibration procedure.
