5.2 Maintenance
5.2.1

Freedom from leaks of sampling system

To ensure accurate exhaust gas measurements it is es-
sential that there are no leaks in the sampling system
(exhaust gas sampling probe, hoses, coarse filters). It is
therefore advisable to conduct the leak test every day.
5.2.2

Exhaust gas sampling probe

Keep the opening at the tip of the exhaust gas sampling
probe clean. In the event of HC residue and conden-
sate, detach the exhaust gas sampling probe from the
hose and blow compressed air through it in the direc-
tion opposite to intake direction.
5.2.� Sampling hose
Check for damage. In the event of HC residue or con-
densate, detach the hose from the analyzer and blow
compressed air through it in the direction opposite to
intake direction.
