4.13.11 Ambient Air Temperature Screen

(Model 110/120/125)

The AMBIENT reading is the combustion-air temperature in either °F or

°C that is used for efficiency calculations. This temperature is measured

by either the T-AIR thermocouple on a continuous basis ( Model 125), or by

the T-STACK thermocouple during start-up (Model 110/120/125). If neither

thermocouple is installed when the analyzer is turned ON, then this

temperature reading comes from a temperature sensor located inside the

analyzer. Refer to Section 4.2.1.
