CO , efficiency, losses, excess air and dew point are calculated val-
2
ues. They can only be calculated if realistic values for the basic pa-
rameters like O
certained that:
are given. The dew point can only be calculated accurately if, in the
menu "Adjustments", the current barometric air pressure value has
been inputted. If the gas temperature falls below the dew point (be-
tween 25 and 65 °C), so efficiency will be calculated with condensa-
tion 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 electro-
chemical reaction to the sensors. This time period lasts approx. 1 to
1.5 minute. For recording, printout and evaluation, wait until the val-
ues do not change anymore. If deviations higher than 2 ppm still
occur by the gas values, they can be due to unstable pressure condi-
tions 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
measurements). 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 in-
termediate recording, so press <F2> (the complete content of the
intermediate memory will be printed).
