Soot Measurement; Oil Trace; Gas Analysis: Data Processing - Ecom EN3 Instruction Manual

4.6.1 Soot measurement

The soot dot measurement is to be performed with the optional heated pistol
grip probe which heating function prevents the filter paper to become wet
because of the humidity issued by the combustion condensate. The filter
paper slot is hereby heated up to approx.
70 °C. Switch hereto the probe heating of the pistol grip probe while selecting
„Adjustments / Internal / Probe heating / <F1>".
Insert a filter paper in the paper slot. Select the line „1st Soot meas.". Press
<Enter> to start the measurement. The display shows the volume to be
sucked and the pump starts sampling. If the soot dot analysis are made with
a manual pump the sucking procedure can be interrupted while pressing
<F4> (result value can immediately be entered).
Once 1,63 litre has been sucked in, the instrument will instruct to input the
opacity degree. Release the filter paper from the probe slot. Compare the
greyness with the opacity scale. Input the result using the numerical keys
and press <Enter>. Repeat this procedure until all 3 soot dot analysis are
completed. The mean value will be calculated and automatically stored.

4.6.1 Oil trace

The result of the oil trace check will be documented as follows:
•
Place cursor on line "Oil trace"
•
Consign the result with <Enter> ("No", "Yes" or "- - - ")
Once all inputs have been entered, press <ESC> to exit the menu. The
measurement is now complete.
