Draft / pressure measurement on combustion test
The draft is measured using the
DELTA
smart
in combination with the extrac-
tion probe either before or after gas measurement.
While inside the measurement window you press the context menu key and
then select the draft/pressure key. During this phase the gas pump stops
working, and gas measurement values are frozen.
In the draft/pressure screen the measured values will be displayed. These val-
ues can be carried over as either draft or pressure value into the gas measure-
ment screen. (The difference between these 2 values are basically the pre-sign
and name before the value
–
a draft in the stack will be displayed as positive
draft)
NOTE
To avoid false readings
The position of the analyzer during pressure sensor ze-
roing is important.
►
During zeroing the analyzer should be in the meas-
urement position.
With the return key you switch back to the gas measurement and the
measured draft value will be visible (unmodifiable) in a different color.
