4.8.1 Low Flow
During sampling or at any time the pump is running the screen may display LOW FLOW. This is an indication
of the following:
• The particle filter needs replacing (a visual check is also necessary)
• Probe or tubing is blocked.
• Internal filters are blocked (Contact service agent)
WARNING!
Under severe conditions of low flow the PUMP will stop and an audible tone will be heard.
The following screen shows the action to be taken:
Check the following for water:-
• Probe line, water trap and particle filter
When the blockage is cleared the instrument should resume normal operation. If it is not possible to clear the
problem then internal damage may have occurred and the unit should be returned to a service center.
4.9 Normal Shutdown Sequence
DO THIS EVERY TIME YOU USE THE ANALYZER
Remove the probe from the vehicle exhaust - TAKE CARE ! THE PROBE WILL BE HOT - and allow it to cool
naturally. Do not immerse the probe in water as this will be drawn into the analyzer and damage the pump
and sensors.
Once the probe is removed from the exhaust allow the readings to return to zero and press
the analyzer will count down from 30 to switch off.
If you have not finished but press by mistake, you can press to return to normal operation
and not switch OFF.
