Gently insert the pin probe (male) at the terminal test port from the terminal side. Do not force the tips into the terminals.

WARNING:

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.
Do not puncture the insulation on a wire. Punctures can cause or eventually lead to poor or intermittent electrical connections.
