Temperature Compensation Coefficient
The Temperature Compensation Coefficient is used to compensate for the effects of
ambient temperatures on the zero stream. The temperature compensation coefficient can
be set by to different means, “Auto Set” which, is automatically calculated based on a
span gas reading at a previously stored temperature and the current temperature, and
“Adjust” which, is a manual adjustment made by adjusting the displayed temperature
compensation coefficient to reach the expected concentration value.
To display the Temperature Compensation Coefficient Screen:
