2. Plug one end of the coiled cable into the telephone jack receptacle on the end
of the T-7 sensor. The jack will only fit one way, so if it will not fit, rotate it
until it slides in easily.
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.
Note: If the TED 200-T is used for diffusion sampling (i.e., incubators, tents,
etc.), the plastic flow diverter must be removed from the T-7 sensor. If
the sensor is used in breathing circuits, etc, the diverter must be used as
shown in Figure 3.

2.1.3 Calibration

After installation of the batteries the display will show HI ALARM 100 and LO
ALARM 17, an AIR CAL message will flash, and the oxygen reading will be blank.
An air calibration must be performed before an oxygen reading will display.
1. For first time and routine maintenance calibrations, make sure that the sensor
and sensor cable have been installed correctly and that the sensor is in room
air uncontaminated with excess oxygen or other gases. For routine
calibrations, set the LO and HI alarm limits to 17 and OFF, respectively.
