AI Customer ServiceIn this video, we will show you how to test a capacitor without using a multimeter. Whether you don''t have a multimeter on hand or simply prefer a different
AI Customer ServiceThis test method is not suitable for capacitors with a capacitу of less than 0.25 μF. They are checked with a special device – an LC meter. In the absence of a function for determining capacitance, the capacitor is checked as follows: Charge it from a DC source. The source voltage is about half that of the capacitor.
An analog (pointer) tester is more suitable for this method: a smoothly deflecting arrow reflects the change in resistance in real-time. The capacitor is checked in a discharged state; otherwise, electric shock or damage to the multimeter is possible. The discharge method depends on the capacity:
In summary, the best solution to test a capacitor without desoldering it actually for the circuit board is either using an ESR meter or smart tweezers. Both work the same and are fine to use. But the ESR meter is preferred for through-hole capacitors, and the latter one is preferred to test SMD capacitors.
You have a capacitance meter or multimeter with a capacitance feature and by using it you can verify the capacitance value of a capacitor. And sometimes you can use the same meter to identify a bad cap if the capacitance value is not in the tolerance range of the manufacture provided data. i.e.
You just cannot test a bad capacitor inside or outside a circuit board by measuring its capacitance value with a capacitor meter or a multimeter. Because in such a situation mentioned devices lead you into false reading, and you may not be able to actually tell if the capacitor you tested was actually a bad or right one. Why?
After that, the leads of the Capacitor should be connected to the Multimeter probes and the readings on the Multimeter must be observed. In the beginning, the resistance will be low and then will gradually increase for a good Capacitor. For a shorted Capacitor, the resistance will low at all times.
