To calibrate the ambient air temperature:
1. In the TEOM Data screen, select the
Service
button to display the
Service screen, then select the
Calibration
button to display the
Calibration screen (Figure 5-32).
2. Select the
Ambient Calibration
button to display the Ambient
Calibration screen (Figure 5-36).
3. Determine the current temperature (°C) at the ambient temperature
sensor using an external thermometer, [°C = 5/9 x (°F - 32)].
4. If the measured value is within ± 2° C of the temperature displayed in
the
Ambient Temperature:
field of the button, no further action is
necessary. Select the
< Back
button to return to the Calibration
screen. If the value is not within ± 2° C of the temperature displayed in
the
Ambient Temperature:
field of the button, select the Ambient
Temperature: button. A keypad will display. Enter the actual
temperature as measured by the external thermometer and press the
Enter
button. The Ambient Temperature Calibration screen will
display with the new entered value. Select the
< Back
button to return
to the Calibration screen.
