contactor starts with a safe, controlled condition and a clear question: is the suspected problem in the coil command, the mechanical movement, or the current path? A multimeter can help separate those paths, but it cannot certify a contactor or replace the model datasheet, the panel drawing, or the site\u2019s energy-control procedure. Testing is therefore a sequence of observations. Isolate the equipment, identify the terminals from the actual drawing, compare the expected contact state with the observed state, and record the result with the model and circuit context.
