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.
