12.2 Core flow search
Before using the core flow search it must be switched-ON:
OK .
The core flow search will help you to find the optimal measurement point in the stack. The core
flow can be identified by the maximum flue gas temperature.
In high reaction time the analyzer displays the trend of the flue gas temperature. Insert the probe
pipe slowly into the stack and position your probe tube when you have reached the maximum flue
gas temperature that is displayed.
Temperature rising Approaching the maximal flue gas tem-
perature
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 displayed (see temperature maximum value on the display –
in this case 69°C).
Maximum temperature has been reached when the arrows (left picture) disappear, max. (right pic-
ture) appears in place of the arrow, and the beeper signal stops. Moving away from the max. tem-
perature 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.
