SMD aluminum electrolytic capacitor

Micro-capacitor capacitors are easy to judge. The multimeter dials a thousand euros, and the red and black pens are connected to the two poles. The hands are placed one to two, and the greater the amplitude, the better.

The hands do not swing at all, and the capacitor under test is broken. The needle does not return to zero, and the measured capacitance has broken down.
