1. Switch the unit ON using "0/I" ON/OFF key.
2. Place the sensor in 100% oxygen.

3. The CALIBRATE button is located on the top of the unit. Turn the button
by pressing down on it and twisting. Rotate until the display reads 100%.
4. Remove the sensor from 100% oxygen. If the flow diverter is attached,
remove it and expose the sensor to room air. The LCD should display 20–
22%.
5. A calibration check may be conducted at any time to assure proper opera-
tion. Remove the diverter and expose the sensor to room air, and verify that
the reading is 20–22%. Expose the sensor to 100% oxygen (preferably using
the diverter and tee adapter in a flow circuit) and verify that the reading is
99–101%.

The TED 60T can be used to analyze gas mixtures for oxygen in two basic modes:
1.) In breathing circuits or other instances where gases are flowing in tubing
circuits.
2.) In confined volumes such as incubators or tents.
When measuring for oxygen in breathing circuits, the diverter must
