6. Gently contact the pin probe (male) at the terminal test port from the terminal side. Do not force the tips
into the terminals.
NOTE:
ο¬
ο¬
For accurate results, always use the pin probe (male).
To prevent damage to the connector terminals, do not insert test
equipment probes, paper clips, or other substitutes as they can
damage the terminals. Damaged terminals cause a poor connection
and an incorrect measurement.
ο¬
Do not puncture the insulation on a wire. Punctures can cause or
eventually lead to poor or intermittent electrical connections.
