Note: The optional combustion-air thermocouple provides a convenient way to measure the burner’s combustion-air temperature when its temperature is not the same as room air. If this thermocouple is not used, then a separate mea-surement of the combustion-air temperature must be made using the probe’s thermocouple during the analyzer’s warm-up period.

The unit should be allowed to stabilize at room temper-ature for at least 2 hours before proceeding with calibration. To maintain accuracy as listed in the Technical Character-istics Section of this manual, the standards used must be at least four times as accurate as the stated accuracy of the Fyrite Pro.
