    The TED 200-T is designed to monitor up to 100 % oxygen concentration in medical gas mixtures. Because it is microprocessor-based, the TED 200-T has a unique combination of features and is very easy to use through a touch panel designed for minimal operator interface.

  • Page 8: Theory Of Operation

    Anesthesia • Respiratory Therapy • Neonatal Care. Theory of Operation The TED 200-T can be divided into two major functional groups: • the T-7 Sensor and • Signal Processing. The analyzer uses Teledyne Electronics Technologies Class T-7 oxygen sensor. The current output from the sensor is fed into the electronic signal processor, where it is used to calculate the oxygen gas concentration and display it on the LCD screen.

  • Page 9: Signal Processing

    Using a microprocessor allows for easier setting of alarms, auto- matic calibration, and self-diagnosis. When the battery runs low or the unit needs recalibration, the TED 200-T tells you so. The oxygen level is calculated and then displayed on the liquid crystal display (LCD) on the front panel.

    CAL, ALARM TEST and OFF keys must be pressed twice in order to activate them. The ON/OFF key needs to be pressed once in order to turn on the TED 200-T, but must be pressed twice to turn it off.

    TEST key once. The display should show BATTERY HRS LEFT as 999. 2.1.2 Sensor Installation or Replacement Note: The T-7 oxygen sensor must be installed before the TED 200-T can be operated. For sterilization procedures, see page 2.8: Sterilization. Note: When a new sensor is installed, typically, the unit is suitable for use immediately after installation.

    3. Plug the other end of the coiled cable into the receptacle located on the right- hand side panel of the TED 200-T. This jack will only fit one way, so do not force it.

  • Page 15: Alarms

    It is very important that air (21 % oxygen) calibration be performed every time the batteries are disconnected or replaced in the TED 200-T. The microprocessor cannot perform its task properly without this data. After 10 seconds a reading of 20–22% oxygen will be displayed. CAL IN 100% will flash for a period of 5 seconds, during which time the reading of 20–22 will con-...

  • Page 16: Use

    Note: Prior to use, always test the batteries and alarms; check calibration, the sensor for leaks and damage, and the alarm settings. The TED 200-T can be used to monitor gas mixtures for oxygen in two basic modes: 1. In breathing circuits or other instances where gases are flowing in tubing circuits.

    T-7. Exposing the sensor to air or gases that do not contain anesthetic agents for a period of time equal to or greater than the exposure interval will eliminate the reading error in most cases. Teledyne Analytical Instruments...

  • Page 18: Care After Use In Nitrous Oxide

    A vacuum must not be drawn on the sensor during the sterilization process. The TED 200-T itself cannot be liquid sterilized or autoclaved. The surface of the case may be wiped with isopropyl alcohol and allowed to air dry. In extreme cases, a mild detergent may be used.

  • Page 19: Do's & Don'ts

    Use cleaning agents or liquids in the cable receptacles or around the battery compartment. • Place the TED 200-T unit itself in a water vapor-saturated environment. • Expose the LCD to excessive sunlight. • Expose the TED 200-T to a condensing water environment such as a mist tent.

    Should the remaining battery life reach 24 hours, the alarms will activate and the screen will display LOW BATTERY. Note: The TED 200-T is designed to automatically check its battery life once per hour. When setting the HI/LO alarms or checking the batteries, the unit will freeze the oxygen reading momentarily.

  • Page 22: Sensor

    If the batteries are still not replaced, the LED and beeper will drain the remaining power and go completely dead. If the TED 200-T will not be used for a period of 30 days or more, the batteries should be removed prior to storage.

    This is why it is important to calibrate the TED 200-T oxygen sensor at regular intervals. It is recommended that the unit be calibrated prior to each use or every 8 hours.

    The information obtained from the TED 200-T should never be used to make adjustments to the primary life- support system, but should only be used as an indication that the primary device may require service and/or calibration.
  • Page 31 Appendices The BATT TEST control of the TED 200-T immediately determines if the batteries need replacing. The TED 200-T should momentarily be removed from the application area and be checked for calibration and sensor integrity. If the TED 200–T can be calibrated, the unit can be assumed to be in good working order and capable of providing readings to specification.
