by an authorized repair center .
If an inlet temperature probe (optional) is connected into the T2 socket during its countdown, the measured temperature
from the inlet probe will be used as the inlet temperature .
If an inlet temperature probe is not connected to the analyzer during countdown the measured temperature from the flue
probe will be used as the inlet temperature .
If neither probe is connected during countdown the analyzer’s internal ambient temperature will be used as the inlet
temperature .
