How to test a safety capacitor?

For safety capacitors above 0.01 μF, the R × 10k range of the multimeter can be used to directly test the capacitor for the charging process and internal short circuit or leakage. The capacity of the capacitor can be estimated according to the amplitude of the pointer swinging to the right during the test.
