Before a launch, the main goal is to confirm system readiness and safety. The pre-launch check verifies that all launcher subsystems are operating correctly, safety interlocks are engaged, software and firmware are nominal, and essential supports like power, cooling, hydraulics, radar, and communications are functioning with no faults. Doing this before mission start and again after any fault or maintenance helps prevent accidents by catching issues early and ensuring the system is in a known, safe state before any firing or action is authorized.

Calibrating radar and adjusting interceptors in real time would be tuning or alignment during operation, not a pre-launch readiness check. Recording a maintenance log after the mission ends is post-mission documentation. Weather considerations are important for planning, but they are separate from the readiness verification performed just before launch.
