medicalManual.RevD.qxd 9/9/04 4:18 PM Page 8 1.2 Component Identification 1.4 MAX-250+ Oxygen Sensor 1.3 Component Description The MAX-250+ oxygen sensor offers stability and extra life. The MAX-250+ is a galvanic, partial pressure sensor that is specific to oxygen. It consists of two electrodes (a cathode and an anode), a teflon membrane and an electrolyte. Oxygen diffuses through the teflon membrane and immediately reacts at a gold cathode.
medicalManual.RevD.qxd 9/9/04 4:18 PM Page 10 2.1.3 Automatic Calibration • If you are unsure about the displayed O2 percentage. (see Factors influencing accurate readings.) After the unit is turned on it will automatically calibrate to room air. The display should be stable and reading 20.9%. A simple calibration may be made with the sensor open to static Ambient air.
medicalManual.RevD.qxd 9/9/04 4:18 PM Page 12 4. Allow the oxygen to saturate the sensor. Although a stable value is usually observed within 30 seconds, allow at least two minutes to ensure that the sensor is completely saturated with the calibration gas. 5. If the MAXO2® + is not already turned on, do so now by pressing the analyzer “ON” button. 6. Press the Cal button on the MAXO2® + until you read the word CAL on the analyzer display. This can take approximately 3 seconds.
medicalManual.RevD.qxd 9/9/04 4:18 PM Page 14 CAL Err St: O2 Sensor reading not stable Wait for displayed oxygen reading to stabilize, when calibrating the device at 100% oxygen. Carefully, bring the two halves of the case together while positioning the wires so they are not pinched between the two case halves. The gasket separating the halves will be captured on the back case half.
medicalManual.RevD.qxd 9/9/04 4:18 PM Page 16 Reconnect the oxygen sensor to the connector on the printed circuit board. Carefully bring the two halves of the case together while positioning the wires to ensure they are not pinched between the two case halves. Make sure the sensor is fully inserted and in the proper orientation. Reinsert the three screws and tighten until the screws are snug. Verify the unit operates properly.
