3.8 Performing Diagnostic Tests
3.8.1. Performing a Slow-Close Test
The DigiTMR S2 offers a unique feature called a “Slow-Close” test. This test can measure the
distance of a breaker’s contact travel from the fully open position to the contact “touch”
position and 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.
Contact channels 1, 2, and 3 and the transducer channel 1 are used for the “Slow-Close” test.
The DigiTMR S2 measures the contact touch and contact wipe for each contact channel.
Contact touch is the distance measured from the contact fully open to the first position where
the contact channel is electrically closed. Contact wipe, or penetration, is the distance
measured from the contact position first electrically closed to the final closed, latching position.
