Perform the measurement in the core stream of the exhaust gas
channel (probe placed in the highest gas temperature area).
Core stream
search
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.
CO , efficiency, losses, excess air and dew point are calculated

values. They can only be calculated if realistic values for the basic
parameters O
ascertained that:
O < 20,5 %

are given. The dew point can only be calculated accurately if, in the
menu "Adjustments", the current barometric air pressure value has
been entered. This value cannot be determined by the ecom-
pro
J2KN
. 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.
