The following sections contain general information applicable to all test 
procedures. Specific information relating to the performance of tests 
using the Free Measurement Procedure may be found i

8: „Operation 

- The Free Measurement 

Procedure‟. 

Information necessary to conduct country specific tests (MOT, AU, APK 
etc.) will be provided in separate documentation. 

 
 

 

 

7.1  Testing Tips

 

• 

Read and follow the procedures in this manual. 

• 

Keep the probe tip openings clean and free from debris. 

• 

Do not place the probe tip in liquids or allow liquids to be drawn into 
the analyser sampling system. Contamination will affect the accuracy 
of any future tests. 

• 

Do not insert the probe into an exhaust pipe until the vehicle engine is 
at normal operating temperature. This allows time for the exhaust 
system to vaporize any residual moisture. 

• 

Never move the analyser by pulling on the probe, sample hose or 
power cord. 

• 

Never drive over the probe, sample hose or power cord. 

• 

Never place any liquids on the analyser that could spill and run into 
the ventilation holes. 

• 

Clean any spilt liquids (gasoline, brake fluid, cleaning solvents etc) 
from the exterior of the analyser immediately in order to protect the 
finish. 

• 

In order to ensure accurate test results, perform a daily Leak Check 
(Vacuum) as described i

9

.2: „Leak Check (Vacuum)‟ 

below. This 

check should also be performed after probe changes or filter service. 

• 

Prolonged use of the analyser in conjunction with a dynamometer and 
a hot running vehicle under load may damage the sample probe and 
affect readings. An alternative sample probe (P/N: 7009-1869-00) is 
available for use in these circumstances.
