, efficiency, losses, excess air and dew point are calculated values. They can only be
calculated if realistic values for the basic parameters like O
2
and the temperatures are
available. It must be ascertained that:
O
2
< 20,7 % and T.Gas - T.Air > 0 °C
are given. 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 <Save> to transfer the
values in the intermediate memory (caution: store
separately gas analysis, CO, O2 check and draught
measurements). They will be kept there for a later printout
and, if need be, for a final data record storage.
Measurement stored in intermediate memory
4.1.3 Printing measured values
There are two ways to print measurements:
1. Print of the measurements stored in intermediate memory
To print the measured values stored in the previous step, press the <Print> key. The
complete content of the intermediate memory will be printed.
2. Printing the currently displayed values, including storage in intermediate memory
To print the measured values currently displayed, press the key <F2>. At the same time the
measured values are stored and overwrite existing intermediate stored values.
Hint
Use the option "Print the currently displayed values" to adjust the time of optimal
measurement results and to print them immediately.
