
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.
