Perform the measurement in the core stream of the exhaust gas
channel (probe placed in the highest gas temperature area).
A trend indication for T.Gas easies the core stream search. As long
as the display shows a + symbol, the measured temperature
increases, it means the probe tip moves towards the core stream. If
a - symbol is displayed, pull the probe out of the core stream and the
temperature sinks. If no temperature change is shown for at least 3
seconds, so the trend indication will be deleted.

values. They can only be calculated if realistic values for the basic
parameters O

ascertained that:

, the current barometric air pressure value has
been entered. This value cannot be determined by the

. If the gas temperature falls below the dew point (between
25 and 65 °C), ETA will be calculated with condensation. In the
display (C) appears behind ETA.
Correct measurement values are displayed first after a short delay,
necessary for the gas transport and the build-up of a stable
electrochemical reaction at the sensors. This time period lasts
approx. between 1 and 1.5 minute. For recording, printout and
evaluation wait until the values do not change anymore. If deviations
higher than 2 ppm still occur by the gas values, they can be due to
unstable pressure conditions in the exhaust channel.
