    DIAGNOSTICS, VERIFICATION, AND TROUBLESHOOTING Performing a Slow-Close Test The CT-7000 S3 offers a unique “Slow-Close” test feature. This test measures the distance a breaker’s contact travels from the fully opened position to the point of contact or “touch” position, and the contact wipe or penetration distance. The test requires the operator to manually jack the breaker’s contact from the fully open position to the fully closed position.
