CO2, efficiency, losses, excess air and dew point are calculated val-
ues. They can only be calculated if values for the basic parameters
like O2 and the temperatures are available. Make sure that:
O2 < 20.5 % and T.Gas - T.Air > + 5 °C
The current barometric pressure must be typed in (in the
<Adjust-
ments> menu) for the dew point to be calculated accurately. If the gas
temperature falls below the dew point (between 25 and 65 °C), then
efficiency will be calculated with condensation gain. In this case, a (K)
is displayed after <Efficiency>.
Correct measurement values are displayed after a short delay. This is
necessary so the gas has time to reach the sensors and to build-up a
stable electrochemical reaction for 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 with the gas values, it may be due to unstable pressure
conditions in the
exhaust channel.
If the measurement values are stable, press the key
<Record> (disk symbol) to transfer the values in the
intermediate memory (caution: store gas analysis,
CO, O2 check and draft measurements separately).
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 needs to be made as the measurement is
taking place, simply press
<F2> (the complete content of the interme-
diate memory will be printed).
