9.6.4 Test Leads
Inspect all test leads weekly for any cuts, kinks or abrasions and
replace any faulty pick-ups or leads.
When routing leads across an engine, ensure that they do not
come into contact with any moving engine components or hot
surfaces such as exhaust manifolds etc.
Trigger clamps should be kept free from oil, grease and other
contaminants and should be cleaned to minimise false triggering
and, therefore, false measurements.
9.6.5 O2 Cell
The unit will indicate when the O2 cell requires replacing by
showing the “Pre-warning change O2 cell” and “Change O2 cell”
warning messages. Refer to 9.5: „Check and/or Install the O2
Cell‟ for further information.
