The analyzer will block readings while the pump is off and display ‘----‘ on all
gas channels.
It is recommended that the analyzer sample fresh air for 60 seconds before the
pump is turned off.
4.7 Regular Checks During Sampling
Care must be taken at all times not to exceed the analyzers operating
specifications, in particular ensure the following:-
•
DO NOT PLACE THE ANALYSER IN THE ENGINE BAY.
•
Do not expose the analyzer to temperatures outside its normal operating
range.
•
DO NOT PLACE THE ANALYSER ON A HOT SURFACE.
•
Ensure that liquid in the water trap does not go over the level indicator.
Note! The indicator only works while the trap is vertical. Water condenses
in the probe line and can quickly fill the water trap when the probe is
moved.
Take care,
watch the water trap closely and empty any water when
it is noticed.
•
Make sure that the in-line particle filter is clean and does not become
blocked. If this filter is allowed to become dirty then damage may occur
inside the analyzer.
Check the following for water:
•
Probe line, water trap and particle filter
When the blockage is cleared the analyzer should resume normal operation. If it
not possible to clear the problem then internal damage may have occurred and
the unit should be returned to a service center.
TIP
: After testing hang the sample hose so that both ends are free to drain
any condensate.
