CO , efficiency, losses, excess air and dew point are calculated values.

They can only be calculated if realistic values for the basic parameters
like O and the temperatures are available. It must be ascertained

that:
are given. The dew point can only be calculated accurately if, in the
menu "Adjustments", the current barometric air pressure value has
been inputed. If the gas temperature falls below the dew point (between
25 and 65 °C), so efficiency will be calculated with condensation gain.
In this case a (K) is displayed after „Efficiency".
Correct measurement values are displayed first after a short delay,
necessary for the gas transport and the build-up of a stable
electrochemical reaction to the sensors. This time period lasts approx.
1 to 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.
If the measurement values are stable and
the results can be printed out, press the
key <Record> (disk symbol) to transfer
the values in the intermediate memory
(caution: store separately gas analysis,
CO, O check and draught measu-
2
rements). They will be kept there for a
later printout and, if need be, for a final
data record storage.
If a printout of the values should be made simultaneously to the
intermediate recording, so press <F2> (the complete content of the
intermediate memory will be printed).
