Before using the core flow search it must be switched-on:
Positioning the probe in the core flow:
Insert the probe pipe slowly into the stack and position your probe pipe
when you have reached the maximum flue gas temperature that is dis-
played (see temperature maximum value on the display
–
in this case
45°C).
Maximum temperature has been reached when the arrows (left picture)
disappear, max. (Right picture) appears in place of the arrow, and the
beeper signal stops. Moving away from the max. Temperature will result
in the bars moving away from the max. Temperature (1 bar is equivalent
to 1°C). Once the right core flow has been achieved, the probe is fixed
with the probe cone screw.

Measured value display
After the core flow search you will see the measurement values on the
display.
Measurement values can be organized on three pages, each page dis-
playing 6 measurement values.
The order of the display is operator settable.
There are direct measured values available such as Oxygen and Temper-
ature as well as calculated values such as dew point, efficiency and CO
2
.
You will also find the same measurement value in different calculated
values such as CO in ppm or CO in mg/kWh.
Values that cannot be displayed are indicated with dashes. Possible rea-
sons for value not being displayed are:
•
Electro chemical sensor was detected as defective during zeroing.
•
External temperature sensors are not connected.
The measurement value T-
Gas is usually read at the connector “T
-
G
as/AUX” (depending on configuration) or if not available from the con-
nector “T1”.
