Determination Of Measured Values - Ecom EN3 Instruction Manual

4.1.3 Determination of measured values

CO2, efficiency, losses, excess air and dew point are calculated values. They
can only be calculated if realistic values for the basic parameters like O2 and
the temperatures are available. It must be ascertained that:
O2 < 20,7 % und 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 chan-
nel.

Measurement stored in
intermediate memory
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 (cau-
tion: store separately gas analysis, CO, O2 check and draught measure-
ments). They will be kept there for a later printout and, if need be, for a final
data record storage.
