Temperature compensation provides compensation for any changes to the
instrument's output signal due to variations in sample gas temperature. The
Model 49i can be operated with or without temperature compensation.
When temperature compensation is on, the display shows the sample gas
temperature (measured by a thermistor on the Interface board). When
temperature compensation is off, the display shows the standard
temperature of 0.0 °C.
• In the Main Menu, choose Instrument Controls > Temperature
