Carry out a reference measurement with a "new" line, if it seems to be nec-
essary.

Replace the sampling lines (Viton hoses) regularly.
Recommended replacement intervals: every 1 000 … 2 000 operating hours.
The material number depends on the length of the sampling line

Information
Heavier soot deposits can occur when using new sampling lines for the first time
straight from the factory and this can also reduce the recorded FSN values.
The lower the measurement values, the higher, the requirement for repeatability,
and reproducibility.
The greater is the influence of the soiling along the entire sampling path.
