((Temperature, Relative Humidity, CO2)
                                          TELAIRE
                 (Temperature, Relative Humidity, CO2)

Launching and Placement of Sensors

   1. Connect the TELAIRE to an outlet using the AC Adapter included.

   2. Connect the TELAIRE to the HOBO RH/TEMP/2xExternal meter
      using the voltage output cable which is a short, black cable with a
      phone-type jack on the end.                             AC Adapter
      Plug into channel 3 on the HOBO meter.

   3. Connect the TELAIRE to the computer using the RS232(HOBO)
                                                                              Connect RS232(HOBO)
      cable supplied.
                                                                                   Cable here
   4. Turn on the meter by pressing the blue POWER button. There will be a 2 second delay. Ten
      seconds will pass before the CO 2 readings are displayed. Wait for one minute until the WARM-UP
      indicator disappears from the upper left hand corner of the meter display.

   5. The device is affected by elevation level. To find the elevation of your school, please follow the
      instructions in the “How To Find Your Elevation” packet that is found in the appendices, Tab 7.
      When you have found your elevation, please continue to step 6.

   6. Follow these steps to enter your approximate elevation. 1) Press MODE button once.
      ELEVATION will begin blinking 2) Press ENTER 3) Press MODE to toggle between meters and
      feet. You probably want to select feet. 4) Use the UP and DOWN arrow buttons to adjust the
      elevation. Elevation can only be moved in increments of 500 so round your elevation to the nearest
      appropriate number. For example: The elevation for the address found on the previous pages is
      894.3 feet. I would log it into the Telaire as 1000 feet. 5) Press enter to save the elevation.

    7. Click on LOGGER and click on LAUNCH.
   8. Change the INTERVAL (Duration) to 30 mins.
   9. Click on the Enable/Disable Channels button.
   10. Check Temperature, Humidity and check the box for
       Channel 3 and select Voltage. Click on Apply.
   11. Click on the Delayed Start box. Type in the date and
       time you would like the meter to start recording.
       Click on START.
   12. Detach the meter from the computer and install according
       to installation instructions. (See next page)

   13. Make certain that the meter is still attached to the power source
       either an extension cord or the outlet itself.
   14. Leave the meter in place until the end of the monitoring period.
       Turn off the meter by pressing the blue POWER button.

Installation of Sensor

   1. Affix the HOBO RH/TEMP/2xExternal meter to the back of the Telaire using the duct tape

       enclosed.

   2. Use the following guidelines to place your Telaire/Hobo for optimal CO 2 reading.

       Here are some general rules of thumb for getting the best CO 2 readings:

             Do not place them near doors or windows because this can prevent you from detecting the

              actual CO2 level in the classroom.

             Avoid areas like water coolers where people might breathe directly on the sensor.

             4 to 6 feet off the floor is best.

             It can also be a good idea to put the sensor close to the air conditioning system's return air

              duct (the air flow will help you get the best readings)

          (John Welch, Telaire)

          With this assumption, if there is good air mixing, the CO2 will evenly disperse in the room.

          Consequently, the reading at the different points of the room should be virtually the same.

   3. Make sure that the Telaire meter is either plugged directly into an outlet or into an extension cord

       for the duration of the test.

   4. Leave the Telaire in place for seven days. On the 7 th day, follow the data instructions found in the

       Downloading and Saving Data section- Tab 4.
