Page 22: Effect Of Pressure
This is why it is important to calibrate the TED 191 Portable Oxygen Monitor at regular intervals. It is recommended that the instrument be calibrated prior to each use or every 8 hours. -
Page 23: Effect Of Humidity
For example, if an 80% oxygen gas mixture is humidified to saturation at room temperature, the resulting gas mixture will contain only 77.5% oxygen. Your TED 191 Portable Oxygen Monitor accurately measures decreases in the oxygen concentration due to the dilution effects of moisture added to gas mixtures. -
Page 24: Effect Of Temperature
ECTION EMPERATURE The Teledyne Electronic Technologies changes in the range of 0 - 40ºC (32 - 106ºF). Since the thermistor that compensates for these changes is located in the rear of the sensor assembly, it is important that gas mixtures, flowing over the front of the sensor, be at room temperature. -
Page 25: Discrepancy In
LEVEN EADINGS The TED 191 is intended to be used as a secondary oxygen monitor, meaning that it is intended to verify the accuracy of and check the oxygen concentration leaving another oxygen mixing device or primary life support system (i.e a blender or anaesthesia machine). Whenever there is a significant difference in the oxygen readings between the primary and secondary monitors, the discrepancy must be resolved immediately. -
