The position of the measured and calculated values (gas analysis)
on the display pages is free selectable.
Proceed as follows to modify the succession:
- press
<F1> to activate the first line on the display
- select the measured or calculated value with the cursor keys
- press
<F1> to activate the next line and so on until the last line
CO

, efficiency, losses, excess air and dew point are calculated val-
ues. They can only be determined if realistic values are available for
the basis values like O
2
and temperatures. It must assured that:
O
2
< 20,5 % and
T. Gas - T. Air > + 5 °C
The dew point can only be determined with accuracy if in the menu
"Adjustments" the current barometric air pressure is entered. This
value cannot be determined by the instrument.
If the gas temperature falls below the dew point (between 25 and 65
°C), Eta will be calculated with condensation. In the display (C) ap-
pears behind Eta.
Correct measurement values are displayed after a short delay of ca.
60 to 90 seconds which are necessary for the gas transport and the
built-up of a stable electrochemical reaction of the sensors. For re-
cording, printouts and evaluation wait until the values get stable. If
the gas values still fluctuate more than 2 ppm, so the reason can be
unstable draught conditions in the exhaust pipe.
If the measurement values are stable and the results recordable, so
press
<record> (disk symbol) to transfer the values in an intermedi-
ate memory (caution: store gas analysis, CO and O
2
measurements
separately).
